It -complements the GNU General Public License, which is a copyleft -license designed for free software. - -We have designed this License in order to use it for manuals for free -software, because free software needs free documentation: a free -program should come with manuals providing the same freedoms that the -software does. But this License is not limited to software manuals; -it can be used for any textual work, regardless of subject matter or -whether it is published as a printed book. We recommend this License -principally for works whose purpose is instruction or reference. - - -1. APPLICABILITY AND DEFINITIONS - -This License applies to any manual or other work, in any medium, that -contains a notice placed by the copyright holder saying it can be -distributed under the terms of this License. Such a notice grants a -world-wide, royalty-free license, unlimited in duration, to use that -work under the conditions stated herein. The "Document", below, -refers to any such manual or work. Any member of the public is a -licensee, and is addressed as "you". You accept the license if you -copy, modify or distribute the work in a way requiring permission -under copyright law. - -A "Modified Version" of the Document means any work containing the -Document or a portion of it, either copied verbatim, or with -modifications and/or translated into another language. - -A "Secondary Section" is a named appendix or a front-matter section of -the Document that deals exclusively with the relationship of the -publishers or authors of the Document to the Document's overall subject -(or to related matters) and contains nothing that could fall directly -within that overall subject. (Thus, if the Document is in part a -textbook of mathematics, a Secondary Section may not explain any -mathematics.) The relationship could be a matter of historical -connection with the subject or with related matters, or of legal, -commercial, philosophical, ethical or political position regarding -them. - -The "Invariant Sections" are certain Secondary Sections whose titles -are designated, as being those of Invariant Sections, in the notice -that says that the Document is released under this License. If a -section does not fit the above definition of Secondary then it is not -allowed to be designated as Invariant. The Document may contain zero -Invariant Sections. If the Document does not identify any Invariant -Sections then there are none. - -The "Cover Texts" are certain short passages of text that are listed, -as Front-Cover Texts or Back-Cover Texts, in the notice that says that -the Document is released under this License. A Front-Cover Text may -be at most 5 words, and a Back-Cover Text may be at most 25 words. - -A "Transparent" copy of the Document means a machine-readable copy, -represented in a format whose specification is available to the -general public, that is suitable for revising the document -straightforwardly with generic text editors or (for images composed of -pixels) generic paint programs or (for drawings) some widely available -drawing editor, and that is suitable for input to text formatters or -for automatic translation to a variety of formats suitable for input -to text formatters. A copy made in an otherwise Transparent file -format whose markup, or absence of markup, has been arranged to thwart -or discourage subsequent modification by readers is not Transparent. -An image format is not Transparent if used for any substantial amount -of text. A copy that is not "Transparent" is called "Opaque". - -Examples of suitable formats for Transparent copies include plain -ASCII without markup, Texinfo input format, LaTeX input format, SGML -or XML using a publicly available DTD, and standard-conforming simple -HTML, PostScript or PDF designed for human modification. Examples of -transparent image formats include PNG, XCF and JPG. Opaque formats -include proprietary formats that can be read and edited only by -proprietary word processors, SGML or XML for which the DTD and/or -processing tools are not generally available, and the -machine-generated HTML, PostScript or PDF produced by some word -processors for output purposes only. - -The "Title Page" means, for a printed book, the title page itself, -plus such following pages as are needed to hold, legibly, the material -this License requires to appear in the title page. For works in -formats which do not have any title page as such, "Title Page" means -the text near the most prominent appearance of the work's title, -preceding the beginning of the body of the text. - -A section "Entitled XYZ" means a named subunit of the Document whose -title either is precisely XYZ or contains XYZ in parentheses following -text that translates XYZ in another language. (Here XYZ stands for a -specific section name mentioned below, such as "Acknowledgements", -"Dedications", "Endorsements", or "History".) To "Preserve the Title" -of such a section when you modify the Document means that it remains a -section "Entitled XYZ" according to this definition. - -The Document may include Warranty Disclaimers next to the notice which -states that this License applies to the Document. These Warranty -Disclaimers are considered to be included by reference in this -License, but only as regards disclaiming warranties: any other -implication that these Warranty Disclaimers may have is void and has -no effect on the meaning of this License. - - -2. VERBATIM COPYING - -You may copy and distribute the Document in any medium, either -commercially or noncommercially, provided that this License, the -copyright notices, and the license notice saying this License applies -to the Document are reproduced in all copies, and that you add no other -conditions whatsoever to those of this License. You may not use -technical measures to obstruct or control the reading or further -copying of the copies you make or distribute. However, you may accept -compensation in exchange for copies. If you distribute a large enough -number of copies you must also follow the conditions in section 3. - -You may also lend copies, under the same conditions stated above, and -you may publicly display copies. - - -3. COPYING IN QUANTITY - -If you publish printed copies (or copies in media that commonly have -printed covers) of the Document, numbering more than 100, and the -Document's license notice requires Cover Texts, you must enclose the -copies in covers that carry, clearly and legibly, all these Cover -Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on -the back cover. Both covers must also clearly and legibly identify -you as the publisher of these copies. The front cover must present -the full title with all words of the title equally prominent and -visible. You may add other material on the covers in addition. -Copying with changes limited to the covers, as long as they preserve -the title of the Document and satisfy these conditions, can be treated -as verbatim copying in other respects. - -If the required texts for either cover are too voluminous to fit -legibly, you should put the first ones listed (as many as fit -reasonably) on the actual cover, and continue the rest onto adjacent -pages. - -If you publish or distribute Opaque copies of the Document numbering -more than 100, you must either include a machine-readable Transparent -copy along with each Opaque copy, or state in or with each Opaque copy -a computer-network location from which the general network-using -public has access to download using public-standard network protocols -a complete Transparent copy of the Document, free of added material. -If you use the latter option, you must take reasonably prudent steps, -when you begin distribution of Opaque copies in quantity, to ensure -that this Transparent copy will remain thus accessible at the stated -location until at least one year after the last time you distribute an -Opaque copy (directly or through your agents or retailers) of that -edition to the public. - -It is requested, but not required, that you contact the authors of the -Document well before redistributing any large number of copies, to give -them a chance to provide you with an updated version of the Document. - - -4. MODIFICATIONS - -You may copy and distribute a Modified Version of the Document under -the conditions of sections 2 and 3 above, provided that you release -the Modified Version under precisely this License, with the Modified -Version filling the role of the Document, thus licensing distribution -and modification of the Modified Version to whoever possesses a copy -of it. In addition, you must do these things in the Modified Version: - -A. Use in the Title Page (and on the covers, if any) a title distinct - from that of the Document, and from those of previous versions - (which should, if there were any, be listed in the History section - of the Document). You may use the same title as a previous version - if the original publisher of that version gives permission. -B. List on the Title Page, as authors, one or more persons or entities - responsible for authorship of the modifications in the Modified - Version, together with at least five of the principal authors of the - Document (all of its principal authors, if it has fewer than five), - unless they release you from this requirement. -C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. -D. Preserve all the copyright notices of the Document. -E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. -F. Include, immediately after the copyright notices, a license notice - giving the public permission to use the Modified Version under the - terms of this License, in the form shown in the Addendum below. -G. Preserve in that license notice the full lists of Invariant Sections - and required Cover Texts given in the Document's license notice. -H. Include an unaltered copy of this License. -I. Preserve the section Entitled "History", Preserve its Title, and add - to it an item stating at least the title, year, new authors, and - publisher of the Modified Version as given on the Title Page. If - there is no section Entitled "History" in the Document, create one - stating the title, year, authors, and publisher of the Document as - given on its Title Page, then add an item describing the Modified - Version as stated in the previous sentence. -J. Preserve the network location, if any, given in the Document for - public access to a Transparent copy of the Document, and likewise - the network locations given in the Document for previous versions - it was based on. These may be placed in the "History" section. - You may omit a network location for a work that was published at - least four years before the Document itself, or if the original - publisher of the version it refers to gives permission. -K. For any section Entitled "Acknowledgements" or "Dedications", - Preserve the Title of the section, and preserve in the section all - the substance and tone of each of the contributor acknowledgements - and/or dedications given therein. -L. Preserve all the Invariant Sections of the Document, - unaltered in their text and in their titles. Section numbers - or the equivalent are not considered part of the section titles. -M. Delete any section Entitled "Endorsements". Such a section - may not be included in the Modified Version. -N. Do not retitle any existing section to be Entitled "Endorsements" - or to conflict in title with any Invariant Section. -O. Preserve any Warranty Disclaimers. - -If the Modified Version includes new front-matter sections or -appendices that qualify as Secondary Sections and contain no material -copied from the Document, you may at your option designate some or all -of these sections as invariant. To do this, add their titles to the -list of Invariant Sections in the Modified Version's license notice. -These titles must be distinct from any other section titles. - -You may add a section Entitled "Endorsements", provided it contains -nothing but endorsements of your Modified Version by various -parties--for example, statements of peer review or that the text has -been approved by an organization as the authoritative definition of a -standard. - -You may add a passage of up to five words as a Front-Cover Text, and a -passage of up to 25 words as a Back-Cover Text, to the end of the list -of Cover Texts in the Modified Version. Only one passage of -Front-Cover Text and one of Back-Cover Text may be added by (or -through arrangements made by) any one entity. If the Document already -includes a cover text for the same cover, previously added by you or -by arrangement made by the same entity you are acting on behalf of, -you may not add another; but you may replace the old one, on explicit -permission from the previous publisher that added the old one. - -The author(s) and publisher(s) of the Document do not by this License -give permission to use their names for publicity for or to assert or -imply endorsement of any Modified Version. - - -5. COMBINING DOCUMENTS - -You may combine the Document with other documents released under this -License, under the terms defined in section 4 above for modified -versions, provided that you include in the combination all of the -Invariant Sections of all of the original documents, unmodified, and -list them all as Invariant Sections of your combined work in its -license notice, and that you preserve all their Warranty Disclaimers. - -The combined work need only contain one copy of this License, and -multiple identical Invariant Sections may be replaced with a single -copy. If there are multiple Invariant Sections with the same name but -different contents, make the title of each such section unique by -adding at the end of it, in parentheses, the name of the original -author or publisher of that section if known, or else a unique number. -Make the same adjustment to the section titles in the list of -Invariant Sections in the license notice of the combined work. - -In the combination, you must combine any sections Entitled "History" -in the various original documents, forming one section Entitled -"History"; likewise combine any sections Entitled "Acknowledgements", -and any sections Entitled "Dedications". You must delete all sections -Entitled "Endorsements". - - -6. COLLECTIONS OF DOCUMENTS - -You may make a collection consisting of the Document and other documents -released under this License, and replace the individual copies of this -License in the various documents with a single copy that is included in -the collection, provided that you follow the rules of this License for -verbatim copying of each of the documents in all other respects. - -You may extract a single document from such a collection, and distribute -it individually under this License, provided you insert a copy of this -License into the extracted document, and follow this License in all -other respects regarding verbatim copying of that document. - - -7. AGGREGATION WITH INDEPENDENT WORKS - -A compilation of the Document or its derivatives with other separate -and independent documents or works, in or on a volume of a storage or -distribution medium, is called an "aggregate" if the copyright -resulting from the compilation is not used to limit the legal rights -of the compilation's users beyond what the individual works permit. -When the Document is included in an aggregate, this License does not -apply to the other works in the aggregate which are not themselves -derivative works of the Document. - -If the Cover Text requirement of section 3 is applicable to these -copies of the Document, then if the Document is less than one half of -the entire aggregate, the Document's Cover Texts may be placed on -covers that bracket the Document within the aggregate, or the -electronic equivalent of covers if the Document is in electronic form. -Otherwise they must appear on printed covers that bracket the whole -aggregate. - - -8. TRANSLATION - -Translation is considered a kind of modification, so you may -distribute translations of the Document under the terms of section 4. -Replacing Invariant Sections with translations requires special -permission from their copyright holders, but you may include -translations of some or all Invariant Sections in addition to the -original versions of these Invariant Sections. You may include a -translation of this License, and all the license notices in the -Document, and any Warranty Disclaimers, provided that you also include -the original English version of this License and the original versions -of those notices and disclaimers. In case of a disagreement between -the translation and the original version of this License or a notice -or disclaimer, the original version will prevail. - -If a section in the Document is Entitled "Acknowledgements", -"Dedications", or "History", the requirement (section 4) to Preserve -its Title (section 1) will typically require changing the actual -title. - - -9. TERMINATION - -You may not copy, modify, sublicense, or distribute the Document except -as expressly provided for under this License. Any other attempt to -copy, modify, sublicense or distribute the Document is void, and will -automatically terminate your rights under this License. However, -parties who have received copies, or rights, from you under this -License will not have their licenses terminated so long as such -parties remain in full compliance. - - -10. FUTURE REVISIONS OF THIS LICENSE - -The Free Software Foundation may publish new, revised versions -of the GNU Free Documentation License from time to time. Such new -versions will be similar in spirit to the present version, but may -differ in detail to address new problems or concerns. See -http://www.gnu.org/copyleft/. - -Each version of the License is given a distinguishing version number. -If the Document specifies that a particular numbered version of this -License "or any later version" applies to it, you have the option of -following the terms and conditions either of that specified version or -of any later version that has been published (not as a draft) by the -Free Software Foundation. If the Document does not specify a version -number of this License, you may choose any version ever published (not -as a draft) by the Free Software Foundation. - - -ADDENDUM: How to use this License for your documents - -To use this License in a document you have written, include a copy of -the License in the document and put the following copyright and -license notices just after the title page: - - Copyright (c) YEAR YOUR NAME. - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.2 - or any later version published by the Free Software Foundation; - with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. - A copy of the license is included in the section entitled "GNU - Free Documentation License". - -If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, -replace the "with...Texts." line with this: - - with the Invariant Sections being LIST THEIR TITLES, with the - Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. - -If you have Invariant Sections without Cover Texts, or some other -combination of the three, merge those two alternatives to suit the -situation. - -If your document contains nontrivial examples of program code, we -recommend releasing these examples in parallel under your choice of -free software license, such as the GNU General Public License, -to permit their use in free software. diff --git a/dep/libFLAC/COPYING.GPL b/dep/libFLAC/COPYING.GPL deleted file mode 100644 index d159169d1..000000000 --- a/dep/libFLAC/COPYING.GPL +++ /dev/null @@ -1,339 +0,0 @@ - GNU GENERAL PUBLIC LICENSE - Version 2, June 1991 - - Copyright (C) 1989, 1991 Free Software Foundation, Inc., - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License along - with this program; if not, write to the Free Software Foundation, Inc., - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - , 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs.

Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights.

If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - - To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

You must have -libogg 1.1.2 or greater, or there will be seeking problems with Ogg FLAC. - -If you are building on x86 and want the assembly optimizations, you will -need to have NASM >= 0.98.30 installed according to the specific instructions -below. - - -=============================================================================== -Note to embedded developers -=============================================================================== - -libFLAC has grown larger over time as more functionality has been -included, but much of it may be unnecessary for a particular embedded -implementation. Unused parts may be pruned by some simple editing of -configure.ac and src/libFLAC/Makefile.am; the following dependency -graph shows which modules may be pruned without breaking things -further down: - -metadata.h - stream_decoder.h - format.h - -stream_encoder.h - stream_decoder.h - format.h - -stream_decoder.h - format.h - -In other words, for pure decoding applications, both the stream encoder -and metadata editing interfaces can be safely removed. - -There is a section dedicated to embedded use in the libFLAC API -HTML documentation (see doc/html/api/index.html). - -Also, there are several places in the libFLAC code with comments marked -with "OPT:" where a #define can be changed to enable code that might be -faster on a specific platform. Experimenting with these can yield faster -binaries. - - -=============================================================================== -Building in a GNU environment -=============================================================================== - -FLAC uses autoconf and libtool for configuring and building. -Better documentation for these will be forthcoming, but in -general, this should work: - -./configure && make && make check && make install - -The 'make check' step is optional; omit it to skip all the tests, -which can take several hours and use around 70-80 megs of disk space. -Even though it will stop with an explicit message on any failure, it -does print out a lot of stuff so you might want to capture the output -to a file if you're having a problem. Also, don't run 'make check' -as root because it confuses some of the tests. - -NOTE: Despite our best efforts it's entirely possible to have -problems when using older versions of autoconf, automake, or -libtool. If you have the latest versions and still can't get it -to work, see the next section on Makefile.lite. - -There are a few FLAC-specific arguments you can give to -`configure': - ---enable-debug : Builds everything with debug symbols and some -extra (and more verbose) error checking. - ---disable-asm-optimizations : Disables the compilation of the -assembly routines. Many routines have assembly versions for -speed and `configure' is pretty good about knowing what is -supported, but you can use this option to build only from the -C sources. May be necessary for building on OS X (Intel). - ---enable-sse : If you are building for an x86 CPU that supports -SSE instructions, you can enable some of the faster routines -if your operating system also supports SSE instructions. flac -can tell if the CPU supports the instructions but currently has -no way to test if the OS does, so if it does, you must pass -this argument to configure to use the SSE routines. If flac -crashes when built with this option you will have to go back and -configure without --enable-sse. Note that ---disable-asm-optimizations implies --disable-sse. - ---enable-local-xmms-plugin : Installs the FLAC XMMS plugin in -$HOME/.xmms/Plugins, instead of the global XMMS plugin area -(usually /usr/lib/xmms/Input). - ---with-ogg= ---with-xmms-prefix= ---with-libiconv-prefix= -Use these if you have these packages but configure can't find them. - -If you want to build completely from scratch (i.e. starting with just -configure.ac and Makefile.am) you should be able to just run 'autogen.sh' -but make sure and read the comments in that file first. - - -=============================================================================== -Building with Makefile.lite -=============================================================================== - -There is a more lightweight build system for do-it-yourself-ers. -It is also useful if configure isn't working, which may be the -case since lately we've had some problems with different versions -of automake and libtool. The Makefile.lite system should work -on GNU systems with few or no adjustments. - -From the top level just 'make -f Makefile.lite'. You can -specify zero or one optional target from 'release', 'debug', -'test', or 'clean'. The default is 'release'. There is no -'install' target but everything you need will end up in the -obj/ directory. - -If you are not on an x86 system or you don't have nasm, you -may have to change the DEFINES in src/libFLAC/Makefile.lite. If -you don't have nasm, remove -DFLAC__HAS_NASM. If your target is -not an x86, change -DFLAC__CPU_IA32 to -DFLAC__CPU_UNKNOWN. - - -=============================================================================== -Building with MSVC -=============================================================================== - -There are .vcproj projects and a master FLAC.sln solution to build all -the libraries and executables with MSVC 2005 or newer. - -Prerequisite: you must have the Ogg libraries installed as described -later. - -Prerequisite: you must have nasm installed, and nasm.exe must be in -your PATH, or the path to nasm.exe must be added to the list of -directories for executable files in the MSVC global options. - -To build everything, run Visual Studio, do File|Open and open FLAC.sln. -From the dropdown in the toolbar, select "Release" instead of "Debug", -then do Build|Build Solution. - -This will build all libraries both statically (e.g. -objs\release\lib\libFLAC_static.lib) and as DLLs (e.g. -objs\release\lib\libFLAC.dll), and it will build all binaries, statically -linked (e.g. objs\release\bin\flac.exe). - -Everything will end up in the "objs" directory. DLLs and .exe files -are all that are needed and can be copied to an installation area and -added to the PATH. - -By default the code is configured with Ogg support. Before building FLAC -you will need to get the Ogg source distribution -(see http://xiph.org/downloads/), build libogg_static.lib (load -win32\libogg_static.sln, change solution configuration to "Release" and -code generation to "Multi-threaded (/MT)", then build), copy libogg_static.lib -into FLAC's 'objs\release\lib' directory, and copy the entire include\ogg tree -into FLAC's 'include' directory (so that there is an 'ogg' directory in FLAC's -'include' directory with the files ogg.h, os_types.h and config_types.h). - -If you want to build without Ogg support, instead edit all .vcproj files -and remove any "FLAC__HAS_OGG" definitions. - - -=============================================================================== -Building on Mac OS X -=============================================================================== - -If you have Fink or a recent version of OS X with the proper autotools, -the GNU flow above should work. - - -=============================================================================== -Building with CMake -=============================================================================== - -CMake is a cross-platform build system. FLAC can be built on Windows, Linux, Mac -OS X using CMake. - -You can use either CMake's CLI or GUI. We recommend you to have a separate build -folder outside the repository in order to not spoil it with generated files. - -CLI ---- - Go to your build folder and run something like this: - - /path/to/flac/build$ cmake /path/to/flac/source - - or e.g. in Windows shell - - C:\path\to\flac\build> cmake \path\to\flac\source - (provided that cmake is in your %PATH% variable) - - That will generate build scripts for the default build system (e.g. Makefiles - for UNIX). After that you start build with a command like this: - - /path/to/flac/build$ make - - And afterwards you can run tests or install the built libraries and headers - - /path/to/flac/build$ make test - /path/to/flac/build$ make install - - If you want use a build system other than default add -G flag to cmake, e.g.: - - /path/to/flac/build$ cmake /path/to/flac/source -GNinja - /path/to/flac/build$ ninja - - or: - - /path/to/flac/build$ cmake /path/to/flac/source -GXcode - - Use cmake --help to see the list of available generators. - - If you have OGG on your system you can tell CMake to use it: - - /path/to/flac/build$ cmake /path/to/flac/source -DWITH_OGG=ON - - If CMake fails to find it you can help CMake by specifying the exact path: - - /path/to/flac/build$ cmake /path/to/flac/source -DWITH_OGG=ON -DOGG_ROOT=/path/to/ogg - - CMake will search for OGG by default so if you don't have it you can tell - cmake to not do so: - - /path/to/flac/build$ cmake /path/to/flac/source -DWITH_OGG=OFF - - Other FLAC's options (e.g. building C++ lib or docs) can also be put to cmake - through -D flag. - -GUI ---- - It is likely that you would prefer to use it on Windows building for Visual - Studio. It's in essence the same process as building using CLI. - - Open cmake-gui. In the window select a source directory (the repository's - root), a build directory (some other directory outside the repository). Then - press button "Configure". CMake will ask you which build system you prefer. - Choose that version of Visual Studio which you have on your system, choose - whether you want to build for x86 or amd64. Press OK. After CMake finishes - press "Generate" button, and after that "Open Project". In response CMake - will launch Visual Studio and open the generated solution. You can use it as - usual but remember that it was generated by CMake. That means that your - changes (e.g. some addidional compile flags) will be lost when you run CMake - next time. - - Again, if you have OGG on your system set WITH_OGG flag in the list of - variables in cmake-gui window before you press "Configure". - - If CMake fails to find MSVC compiler then running cmake-gui from MS Developer - comand prompt should help. diff --git a/dep/libFLAC/include/FLAC/all.h b/dep/libFLAC/include/FLAC/all.h deleted file mode 100644 index b37a68fc8..000000000 --- a/dep/libFLAC/include/FLAC/all.h +++ /dev/null @@ -1,371 +0,0 @@ -/* libFLAC - Free Lossless Audio Codec library - * Copyright (C) 2000-2009 Josh Coalson - * Copyright (C) 2011-2016 Xiph.Org Foundation - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * - * - Redistributions of source code must retain the above copyright - * notice, this list of conditions and the following disclaimer. - * - * - Redistributions in binary form must reproduce the above copyright - * notice, this list of conditions and the following disclaimer in the - * documentation and/or other materials provided with the distribution. - * - * - Neither the name of the Xiph.org Foundation nor the names of its - * contributors may be used to endorse or promote products derived from - * this software without specific prior written permission. - * - * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS - * ``AS IS'' AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT - * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR - * A PARTICULAR PURPOSE ARE DISCLAIMED.

It is - * highly interconnected; this introduction should give you a top - * level idea of the structure and how to find the information you - * need. As a prerequisite you should have at least a basic - * knowledge of the FLAC format, documented - * here. - * - * \section c_api FLAC C API - * - * The FLAC C API is the interface to libFLAC, a set of structures - * describing the components of FLAC streams, and functions for - * encoding and decoding streams, as well as manipulating FLAC - * metadata in files. The public include files will be installed - * in your include area (for example /usr/include/FLAC/...). - * - * By writing a little code and linking against libFLAC, it is - * relatively easy to add FLAC support to another program. The - * library is licensed under Xiph's BSD license. - * Complete source code of libFLAC as well as the command-line - * encoder and plugins is available and is a useful source of - * examples. - * - * Aside from encoders and decoders, libFLAC provides a powerful - * metadata interface for manipulating metadata in FLAC files. It - * allows the user to add, delete, and modify FLAC metadata blocks - * and it can automatically take advantage of PADDING blocks to avoid - * rewriting the entire FLAC file when changing the size of the - * metadata. - * - * libFLAC usually only requires the standard C library and C math - * library. In particular, threading is not used so there is no - * dependency on a thread library. However, libFLAC does not use - * global variables and should be thread-safe. - * - * libFLAC also supports encoding to and decoding from Ogg FLAC. - * However the metadata editing interfaces currently have limited - * read-only support for Ogg FLAC files. - * - * \section cpp_api FLAC C++ API - * - * The FLAC C++ API is a set of classes that encapsulate the - * structures and functions in libFLAC. They provide slightly more - * functionality with respect to metadata but are otherwise - * equivalent. For the most part, they share the same usage as - * their counterparts in libFLAC, and the FLAC C API documentation - * can be used as a supplement. The public include files - * for the C++ API will be installed in your include area (for - * example /usr/include/FLAC++/...). - * - * libFLAC++ is also licensed under - * Xiph's BSD license. - * - * \section getting_started Getting Started - * - * A good starting point for learning the API is to browse through - * the modules. Modules are logical - * groupings of related functions or classes, which correspond roughly - * to header files or sections of header files. Each module includes a - * detailed description of the general usage of its functions or - * classes. - * - * From there you can go on to look at the documentation of - * individual functions. You can see different views of the individual - * functions through the links in top bar across this page. - * - * If you prefer a more hands-on approach, you can jump right to some - * example code. - * - * \section porting_guide Porting Guide - * - * Starting with FLAC 1.1.3 a \link porting Porting Guide \endlink - * has been introduced which gives detailed instructions on how to - * port your code to newer versions of FLAC. - * - * \section embedded_developers Embedded Developers - * - * libFLAC has grown larger over time as more functionality has been - * included, but much of it may be unnecessary for a particular embedded - * implementation. Unused parts may be pruned by some simple editing of - * src/libFLAC/Makefile.am. In general, the decoders, encoders, and - * metadata interface are all independent from each other. - * - * It is easiest to just describe the dependencies: - * - * - All modules depend on the \link flac_format Format \endlink module. - * - The decoders and encoders depend on the bitbuffer. - * - The decoder is independent of the encoder. The encoder uses the - * decoder because of the verify feature, but this can be removed if - * not needed. - * - Parts of the metadata interface require the stream decoder (but not - * the encoder). - * - Ogg support is selectable through the compile time macro - * \c FLAC__HAS_OGG. - * - * For example, if your application only requires the stream decoder, no - * encoder, and no metadata interface, you can remove the stream encoder - * and the metadata interface, which will greatly reduce the size of the - * library. - * - * Also, there are several places in the libFLAC code with comments marked - * with "OPT:" where a #define can be changed to enable code that might be - * faster on a specific platform. Experimenting with these can yield faster - * binaries. - */ - -/** \defgroup porting Porting Guide for New Versions - * - * This module describes differences in the library interfaces from - * version to version. It assists in the porting of code that uses - * the libraries to newer versions of FLAC. - * - * One simple facility for making porting easier that has been added - * in FLAC 1.1.3 is a set of \c #defines in \c export.h of each - * library's includes (e.g. \c include/FLAC/export.h). The - * \c #defines mirror the libraries' - * libtool version numbers, - * e.g. in libFLAC there are \c FLAC_API_VERSION_CURRENT, - * \c FLAC_API_VERSION_REVISION, and \c FLAC_API_VERSION_AGE. - * These can be used to support multiple versions of an API during the - * transition phase, e.g. - * - * \code - * #if !defined(FLAC_API_VERSION_CURRENT) || FLAC_API_VERSION_CURRENT <= 7 - * legacy code - * #else - * new code - * #endif - * \endcode - * - * The source will work for multiple versions and the legacy code can - * easily be removed when the transition is complete. - * - * Another available symbol is FLAC_API_SUPPORTS_OGG_FLAC (defined in - * include/FLAC/export.h), which can be used to determine whether or not - * the library has been compiled with support for Ogg FLAC. This is - * simpler than trying to call an Ogg init function and catching the - * error. - */ - -/** \defgroup porting_1_1_2_to_1_1_3 Porting from FLAC 1.1.2 to 1.1.3 - * \ingroup porting - * - * \brief - * This module describes porting from FLAC 1.1.2 to FLAC 1.1.3. - * - * The main change between the APIs in 1.1.2 and 1.1.3 is that they have - * been simplified. First, libOggFLAC has been merged into libFLAC and - * libOggFLAC++ has been merged into libFLAC++. Second, both the three - * decoding layers and three encoding layers have been merged into a - * single stream decoder and stream encoder. That is, the functionality - * of FLAC__SeekableStreamDecoder and FLAC__FileDecoder has been merged - * into FLAC__StreamDecoder, and FLAC__SeekableStreamEncoder and - * FLAC__FileEncoder into FLAC__StreamEncoder. Only the - * FLAC__StreamDecoder and FLAC__StreamEncoder remain. What this means - * is there is now a single API that can be used to encode or decode - * streams to/from native FLAC or Ogg FLAC and the single API can work - * on both seekable and non-seekable streams. - * - * Instead of creating an encoder or decoder of a certain layer, now the - * client will always create a FLAC__StreamEncoder or - * FLAC__StreamDecoder. The old layers are now differentiated by the - * initialization function. For example, for the decoder, - * FLAC__stream_decoder_init() has been replaced by - * FLAC__stream_decoder_init_stream(). This init function takes - * callbacks for the I/O, and the seeking callbacks are optional. This - * allows the client to use the same object for seekable and - * non-seekable streams. For decoding a FLAC file directly, the client - * can use FLAC__stream_decoder_init_file() and pass just a filename - * and fewer callbacks; most of the other callbacks are supplied - * internally. For situations where fopen()ing by filename is not - * possible (e.g. Unicode filenames on Windows) the client can instead - * open the file itself and supply the FILE* to - * FLAC__stream_decoder_init_FILE(). The init functions now returns a - * FLAC__StreamDecoderInitStatus instead of FLAC__StreamDecoderState. - * Since the callbacks and client data are now passed to the init - * function, the FLAC__stream_decoder_set_*_callback() functions and - * FLAC__stream_decoder_set_client_data() are no longer needed. The - * rest of the calls to the decoder are the same as before. - * - * There are counterpart init functions for Ogg FLAC, e.g. - * FLAC__stream_decoder_init_ogg_stream(). All the rest of the calls - * and callbacks are the same as for native FLAC. - * - * As an example, in FLAC 1.1.2 a seekable stream decoder would have - * been set up like so: - * - * \code - * FLAC__SeekableStreamDecoder *decoder = FLAC__seekable_stream_decoder_new(); - * if(decoder == NULL) do_something; - * FLAC__seekable_stream_decoder_set_md5_checking(decoder, true); - * [... other settings ...] - * FLAC__seekable_stream_decoder_set_read_callback(decoder, my_read_callback); - * FLAC__seekable_stream_decoder_set_seek_callback(decoder, my_seek_callback); - * FLAC__seekable_stream_decoder_set_tell_callback(decoder, my_tell_callback); - * FLAC__seekable_stream_decoder_set_length_callback(decoder, my_length_callback); - * FLAC__seekable_stream_decoder_set_eof_callback(decoder, my_eof_callback); - * FLAC__seekable_stream_decoder_set_write_callback(decoder, my_write_callback); - * FLAC__seekable_stream_decoder_set_metadata_callback(decoder, my_metadata_callback); - * FLAC__seekable_stream_decoder_set_error_callback(decoder, my_error_callback); - * FLAC__seekable_stream_decoder_set_client_data(decoder, my_client_data); - * if(FLAC__seekable_stream_decoder_init(decoder) != FLAC__SEEKABLE_STREAM_DECODER_OK) do_something; - * \endcode - * - * In FLAC 1.1.3 it is like this: - * - * \code - * FLAC__StreamDecoder *decoder = FLAC__stream_decoder_new(); - * if(decoder == NULL) do_something; - * FLAC__stream_decoder_set_md5_checking(decoder, true); - * [... other settings ...] - * if(FLAC__stream_decoder_init_stream( - * decoder, - * my_read_callback, - * my_seek_callback, // or NULL - * my_tell_callback, // or NULL - * my_length_callback, // or NULL - * my_eof_callback, // or NULL - * my_write_callback, - * my_metadata_callback, // or NULL - * my_error_callback, - * my_client_data - * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; - * \endcode - * - * or you could do; - * - * \code - * [...] - * FILE *file = fopen("somefile.flac","rb"); - * if(file == NULL) do_somthing; - * if(FLAC__stream_decoder_init_FILE( - * decoder, - * file, - * my_write_callback, - * my_metadata_callback, // or NULL - * my_error_callback, - * my_client_data - * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; - * \endcode - * - * or just: - * - * \code - * [...] - * if(FLAC__stream_decoder_init_file( - * decoder, - * "somefile.flac", - * my_write_callback, - * my_metadata_callback, // or NULL - * my_error_callback, - * my_client_data - * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; - * \endcode - * - * Another small change to the decoder is in how it handles unparseable - * streams. Before, when the decoder found an unparseable stream - * (reserved for when the decoder encounters a stream from a future - * encoder that it can't parse), it changed the state to - * \c FLAC__STREAM_DECODER_UNPARSEABLE_STREAM. Now the decoder instead - * drops sync and calls the error callback with a new error code - * \c FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM. This is - * more robust. If your error callback does not discriminate on the the - * error state, your code does not need to be changed. - * - * The encoder now has a new setting: - * FLAC__stream_encoder_set_apodization(). This is for setting the - * method used to window the data before LPC analysis. You only need to - * add a call to this function if the default is not suitable. There - * are also two new convenience functions that may be useful: - * FLAC__metadata_object_cuesheet_calculate_cddb_id() and - * FLAC__metadata_get_cuesheet(). - * - * The \a bytes parameter to FLAC__StreamDecoderReadCallback, - * FLAC__StreamEncoderReadCallback, and FLAC__StreamEncoderWriteCallback - * is now \c size_t instead of \c uint32_t. - */ - -/** \defgroup porting_1_1_3_to_1_1_4 Porting from FLAC 1.1.3 to 1.1.4 - * \ingroup porting - * - * \brief - * This module describes porting from FLAC 1.1.3 to FLAC 1.1.4. - * - * There were no changes to any of the interfaces from 1.1.3 to 1.1.4. - * There was a slight change in the implementation of - * FLAC__stream_encoder_set_metadata(); the function now makes a copy - * of the \a metadata array of pointers so the client no longer needs - * to maintain it after the call.

This level is write- - * efficient in most cases (more on this below), and uses less memory - * than level 2. - * - * Level 2: - * Read-write access to all metadata blocks. This level is write- - * efficient in all cases, but uses more memory since all metadata for - * the whole file is read into memory and manipulated before writing - * out again. - * - * What do we mean by efficient? Since FLAC metadata appears at the - * beginning of the file, when writing metadata back to a FLAC file - * it is possible to grow or shrink the metadata such that the entire - * file must be rewritten. However, if the size remains the same during - * changes or PADDING blocks are utilized, only the metadata needs to be - * overwritten, which is much faster. - * - * Efficient means the whole file is rewritten at most one time, and only - * when necessary. Level 1 is not efficient only in the case that you - * cause more than one metadata block to grow or shrink beyond what can - * be accommodated by padding. In this case you should probably use level - * 2, which allows you to edit all the metadata for a file in memory and - * write it out all at once. - * - * All levels know how to skip over and not disturb an ID3v2 tag at the - * front of the file. - * - * All levels access files via their filenames. In addition, level 2 - * has additional alternative read and write functions that take an I/O - * handle and callbacks, for situations where access by filename is not - * possible. - * - * In addition to the three interfaces, this module defines functions for - * creating and manipulating various metadata objects in memory. As we see - * from the Format module, FLAC metadata blocks in memory are very primitive - * structures for storing information in an efficient way. Reading - * information from the structures is easy but creating or modifying them - * directly is more complex. The metadata object routines here facilitate - * this by taking care of the consistency and memory management drudgery. - * - * Unless you will be using the level 1 or 2 interfaces to modify existing - * metadata however, you will not probably not need these. - * - * From a dependency standpoint, none of the encoders or decoders require - * the metadata module.

We decree that all pointers to data in the object are - * owned by the object and memory-managed by the object. - * - * Use the FLAC__metadata_object_new() and FLAC__metadata_object_delete() - * functions to create all instances. When using the - * FLAC__metadata_object_set_*() functions to set pointers to data, set - * \a copy to \c true to have the function make it's own copy of the data, or - * to \c false to give the object ownership of your data. In the latter case - * your pointer must be freeable by free() and will be free()d when the object - * is FLAC__metadata_object_delete()d. It is legal to pass a null pointer as - * the data pointer to a FLAC__metadata_object_set_*() function as long as - * the length argument is 0 and the \a copy argument is \c false. - * - * The FLAC__metadata_object_new() and FLAC__metadata_object_clone() function - * will return \c NULL in the case of a memory allocation error, otherwise a new - * object.

This is not counted - * toward the length or stored in the stream, but it can make working with plain - * comments (those that don't contain embedded-NULs in the value) easier. - * Entries passed into these functions have trailing NULs added if missing, and - * returned entries are guaranteed to have a trailing NUL. - * - * The FLAC__metadata_object_vorbiscomment_*() functions that take a Vorbis - * comment entry/name/value will first validate that it complies with the Vorbis - * comment specification and return false if it does not. - * - * There is no need to recalculate the length field on metadata blocks you - * have modified.

For more - * info see the \link flac_stream_decoder stream decoder \endlink module. - */ - -/** \defgroup flac_stream_decoder FLAC/stream_decoder.h: stream decoder interface - * \ingroup flac_decoder - * - * \brief - * This module contains the functions which implement the stream - * decoder. - * - * The stream decoder can decode native FLAC, and optionally Ogg FLAC - * (check FLAC_API_SUPPORTS_OGG_FLAC) streams and files. - * - * The basic usage of this decoder is as follows: - * - The program creates an instance of a decoder using - * FLAC__stream_decoder_new(). - * - The program overrides the default settings using - * FLAC__stream_decoder_set_*() functions. - * - The program initializes the instance to validate the settings and - * prepare for decoding using - * - FLAC__stream_decoder_init_stream() or FLAC__stream_decoder_init_FILE() - * or FLAC__stream_decoder_init_file() for native FLAC, - * - FLAC__stream_decoder_init_ogg_stream() or FLAC__stream_decoder_init_ogg_FILE() - * or FLAC__stream_decoder_init_ogg_file() for Ogg FLAC - * - The program calls the FLAC__stream_decoder_process_*() functions - * to decode data, which subsequently calls the callbacks. - * - The program finishes the decoding with FLAC__stream_decoder_finish(), - * which flushes the input and output and resets the decoder to the - * uninitialized state. - * - The instance may be used again or deleted with - * FLAC__stream_decoder_delete(). - * - * In more detail, the program will create a new instance by calling - * FLAC__stream_decoder_new(), then call FLAC__stream_decoder_set_*() - * functions to override the default decoder options, and call - * one of the FLAC__stream_decoder_init_*() functions. - * - * There are three initialization functions for native FLAC, one for - * setting up the decoder to decode FLAC data from the client via - * callbacks, and two for decoding directly from a FLAC file. - * - * For decoding via callbacks, use FLAC__stream_decoder_init_stream(). - * You must also supply several callbacks for handling I/O. Some (like - * seeking) are optional, depending on the capabilities of the input. - * - * For decoding directly from a file, use FLAC__stream_decoder_init_FILE() - * or FLAC__stream_decoder_init_file(). Then you must only supply an open - * \c FILE* or filename and fewer callbacks; the decoder will handle - * the other callbacks internally. - * - * There are three similarly-named init functions for decoding from Ogg - * FLAC streams. Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the - * library has been built with Ogg support. - * - * Once the decoder is initialized, your program will call one of several - * functions to start the decoding process: - * - * - FLAC__stream_decoder_process_single() - Tells the decoder to process at - * most one metadata block or audio frame and return, calling either the - * metadata callback or write callback, respectively, once. If the decoder - * loses sync it will return with only the error callback being called. - * - FLAC__stream_decoder_process_until_end_of_metadata() - Tells the decoder - * to process the stream from the current location and stop upon reaching - * the first audio frame. The client will get one metadata, write, or error - * callback per metadata block, audio frame, or sync error, respectively. - * - FLAC__stream_decoder_process_until_end_of_stream() - Tells the decoder - * to process the stream from the current location until the read callback - * returns FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM or - * FLAC__STREAM_DECODER_READ_STATUS_ABORT. The client will get one metadata, - * write, or error callback per metadata block, audio frame, or sync error, - * respectively. - * - * When the decoder has finished decoding (normally or through an abort), - * the instance is finished by calling FLAC__stream_decoder_finish(), which - * ensures the decoder is in the correct state and frees memory. Then the - * instance may be deleted with FLAC__stream_decoder_delete() or initialized - * again to decode another stream. - * - * Seeking is exposed through the FLAC__stream_decoder_seek_absolute() method. - * At any point after the stream decoder has been initialized, the client can - * call this function to seek to an exact sample within the stream. - * Subsequently, the first time the write callback is called it will be - * passed a (possibly partial) block starting at that sample. - * - * If the client cannot seek via the callback interface provided, but still - * has another way of seeking, it can flush the decoder using - * FLAC__stream_decoder_flush() and start feeding data from the new position - * through the read callback. - * - * The stream decoder also provides MD5 signature checking. If this is - * turned on before initialization, FLAC__stream_decoder_finish() will - * report when the decoded MD5 signature does not match the one stored - * in the STREAMINFO block. MD5 checking is automatically turned off - * (until the next FLAC__stream_decoder_reset()) if there is no signature - * in the STREAMINFO block or when a seek is attempted. - * - * The FLAC__stream_decoder_set_metadata_*() functions deserve special - * attention. By default, the decoder only calls the metadata_callback for - * the STREAMINFO block. These functions allow you to tell the decoder - * explicitly which blocks to parse and return via the metadata_callback - * and/or which to skip. Use a FLAC__stream_decoder_set_metadata_respond_all(), - * FLAC__stream_decoder_set_metadata_ignore() ... or FLAC__stream_decoder_set_metadata_ignore_all(), - * FLAC__stream_decoder_set_metadata_respond() ... sequence to exactly specify - * which blocks to return. Remember that metadata blocks can potentially - * be big (for example, cover art) so filtering out the ones you don't - * use can reduce the memory requirements of the decoder. Also note the - * special forms FLAC__stream_decoder_set_metadata_respond_application(id) - * and FLAC__stream_decoder_set_metadata_ignore_application(id) for - * filtering APPLICATION blocks based on the application ID. - * - * STREAMINFO and SEEKTABLE blocks are always parsed and used internally, but - * they still can legally be filtered from the metadata_callback. - * - * \note - * The "set" functions may only be called when the decoder is in the - * state FLAC__STREAM_DECODER_UNINITIALIZED, i.e. after - * FLAC__stream_decoder_new() or FLAC__stream_decoder_finish(), but - * before FLAC__stream_decoder_init_*(). If this is the case they will - * return \c true, otherwise \c false. - * - * \note - * FLAC__stream_decoder_finish() resets all settings to the constructor - * defaults, including the callbacks. - * - * \{ - */ - - -/** State values for a FLAC__StreamDecoder - * - * The decoder's state can be obtained by calling FLAC__stream_decoder_get_state(). - */ -typedef enum { - - FLAC__STREAM_DECODER_SEARCH_FOR_METADATA = 0, - /**< The decoder is ready to search for metadata. */ - - FLAC__STREAM_DECODER_READ_METADATA, - /**< The decoder is ready to or is in the process of reading metadata. */ - - FLAC__STREAM_DECODER_SEARCH_FOR_FRAME_SYNC, - /**< The decoder is ready to or is in the process of searching for the - * frame sync code. - */ - - FLAC__STREAM_DECODER_READ_FRAME, - /**< The decoder is ready to or is in the process of reading a frame. */ - - FLAC__STREAM_DECODER_END_OF_STREAM, - /**< The decoder has reached the end of the stream. */ - - FLAC__STREAM_DECODER_OGG_ERROR, - /**< An error occurred in the underlying Ogg layer. */ - - FLAC__STREAM_DECODER_SEEK_ERROR, - /**< An error occurred while seeking.

At a minimum, the following - * functions should be called: - * - FLAC__stream_encoder_set_channels() - * - FLAC__stream_encoder_set_bits_per_sample() - * - FLAC__stream_encoder_set_sample_rate() - * - FLAC__stream_encoder_set_ogg_serial_number() (if encoding to Ogg FLAC) - * - FLAC__stream_encoder_set_total_samples_estimate() (if known) - * - If the application wants to control the compression level or set its own - * metadata, then the following should also be called: - * - FLAC__stream_encoder_set_compression_level() - * - FLAC__stream_encoder_set_verify() - * - FLAC__stream_encoder_set_metadata() - * - The rest of the set functions should only be called if the client needs - * exact control over how the audio is compressed; thorough understanding - * of the FLAC format is necessary to achieve good results. - * - The program initializes the instance to validate the settings and - * prepare for encoding using - * - FLAC__stream_encoder_init_stream() or FLAC__stream_encoder_init_FILE() - * or FLAC__stream_encoder_init_file() for native FLAC - * - FLAC__stream_encoder_init_ogg_stream() or FLAC__stream_encoder_init_ogg_FILE() - * or FLAC__stream_encoder_init_ogg_file() for Ogg FLAC - * - The program calls FLAC__stream_encoder_process() or - * FLAC__stream_encoder_process_interleaved() to encode data, which - * subsequently calls the callbacks when there is encoder data ready - * to be written. - * - The program finishes the encoding with FLAC__stream_encoder_finish(), - * which causes the encoder to encode any data still in its input pipe, - * update the metadata with the final encoding statistics if output - * seeking is possible, and finally reset the encoder to the - * uninitialized state. - * - The instance may be used again or deleted with - * FLAC__stream_encoder_delete(). - * - * In more detail, the stream encoder functions similarly to the - * \link flac_stream_decoder stream decoder \endlink, but has fewer - * callbacks and more options. Typically the client will create a new - * instance by calling FLAC__stream_encoder_new(), then set the necessary - * parameters with FLAC__stream_encoder_set_*(), and initialize it by - * calling one of the FLAC__stream_encoder_init_*() functions. - * - * Unlike the decoders, the stream encoder has many options that can - * affect the speed and compression ratio. When setting these parameters - * you should have some basic knowledge of the format (see the - * user-level documentation - * or the formal description). The - * FLAC__stream_encoder_set_*() functions themselves do not validate the - * values as many are interdependent. The FLAC__stream_encoder_init_*() - * functions will do this, so make sure to pay attention to the state - * returned by FLAC__stream_encoder_init_*() to make sure that it is - * FLAC__STREAM_ENCODER_INIT_STATUS_OK. Any parameters that are not set - * before FLAC__stream_encoder_init_*() will take on the defaults from - * the constructor. - * - * There are three initialization functions for native FLAC, one for - * setting up the encoder to encode FLAC data to the client via - * callbacks, and two for encoding directly to a file. - * - * For encoding via callbacks, use FLAC__stream_encoder_init_stream(). - * You must also supply a write callback which will be called anytime - * there is raw encoded data to write. If the client can seek the output - * it is best to also supply seek and tell callbacks, as this allows the - * encoder to go back after encoding is finished to write back - * information that was collected while encoding, like seek point offsets, - * frame sizes, etc. - * - * For encoding directly to a file, use FLAC__stream_encoder_init_FILE() - * or FLAC__stream_encoder_init_file(). Then you must only supply a - * filename or open \c FILE*; the encoder will handle all the callbacks - * internally. You may also supply a progress callback for periodic - * notification of the encoding progress. - * - * There are three similarly-named init functions for encoding to Ogg - * FLAC streams. Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the - * library has been built with Ogg support. - * - * The call to FLAC__stream_encoder_init_*() currently will also immediately - * call the write callback several times, once with the \c fLaC signature, - * and once for each encoded metadata block. Note that for Ogg FLAC - * encoding you will usually get at least twice the number of callbacks than - * with native FLAC, one for the Ogg page header and one for the page body. - * - * After initializing the instance, the client may feed audio data to the - * encoder in one of two ways: - * - * - Channel separate, through FLAC__stream_encoder_process() - The client - * will pass an array of pointers to buffers, one for each channel, to - * the encoder, each of the same length. The samples need not be - * block-aligned, but each channel should have the same number of samples. - * - Channel interleaved, through - * FLAC__stream_encoder_process_interleaved() - The client will pass a single - * pointer to data that is channel-interleaved (i.e. channel0_sample0, - * channel1_sample0, ... , channelN_sample0, channel0_sample1, ...). - * Again, the samples need not be block-aligned but they must be - * sample-aligned, i.e. the first value should be channel0_sample0 and - * the last value channelN_sampleM. - * - * Note that for either process call, each sample in the buffers should be a - * signed integer, right-justified to the resolution set by - * FLAC__stream_encoder_set_bits_per_sample(). For example, if the resolution - * is 16 bits per sample, the samples should all be in the range [-32768,32767]. - * - * When the client is finished encoding data, it calls - * FLAC__stream_encoder_finish(), which causes the encoder to encode any - * data still in its input pipe, and call the metadata callback with the - * final encoding statistics. Then the instance may be deleted with - * FLAC__stream_encoder_delete() or initialized again to encode another - * stream. - * - * For programs that write their own metadata, but that do not know the - * actual metadata until after encoding, it is advantageous to instruct - * the encoder to write a PADDING block of the correct size, so that - * instead of rewriting the whole stream after encoding, the program can - * just overwrite the PADDING block. If only the maximum size of the - * metadata is known, the program can write a slightly larger padding - * block, then split it after encoding. - * - * Make sure you understand how lengths are calculated. All FLAC metadata - * blocks have a 4 byte header which contains the type and length. This - * length does not include the 4 bytes of the header. See the format page - * for the specification of metadata blocks and their lengths. - * - * \note - * If you are writing the FLAC data to a file via callbacks, make sure it - * is open for update (e.g. mode "w+" for stdio streams). This is because - * after the first encoding pass, the encoder will try to seek back to the - * beginning of the stream, to the STREAMINFO block, to write some data - * there. (If using FLAC__stream_encoder_init*_file() or - * FLAC__stream_encoder_init*_FILE(), the file is managed internally.) - * - * \note - * The "set" functions may only be called when the encoder is in the - * state FLAC__STREAM_ENCODER_UNINITIALIZED, i.e. after - * FLAC__stream_encoder_new() or FLAC__stream_encoder_finish(), but - * before FLAC__stream_encoder_init_*(). If this is the case they will - * return \c true, otherwise \c false. - * - * \note - * FLAC__stream_encoder_finish() resets all settings to the constructor - * defaults. - * - * \{ - */ - - -/** State values for a FLAC__StreamEncoder. - * - * The encoder's state can be obtained by calling FLAC__stream_encoder_get_state(). - * - * If the encoder gets into any other state besides \c FLAC__STREAM_ENCODER_OK - * or \c FLAC__STREAM_ENCODER_UNINITIALIZED, it becomes invalid for encoding and - * must be deleted with FLAC__stream_encoder_delete(). - */ -typedef enum { - - FLAC__STREAM_ENCODER_OK = 0, - /**< The encoder is in the normal OK state and samples can be processed. */ - - FLAC__STREAM_ENCODER_UNINITIALIZED, - /**< The encoder is in the uninitialized state; one of the - * FLAC__stream_encoder_init_*() functions must be called before samples - * can be processed. - */ - - FLAC__STREAM_ENCODER_OGG_ERROR, - /**< An error occurred in the underlying Ogg layer. */ - - FLAC__STREAM_ENCODER_VERIFY_DECODER_ERROR, - /**< An error occurred in the underlying verify stream decoder; - * check FLAC__stream_encoder_get_verify_decoder_state(). - */ - - FLAC__STREAM_ENCODER_VERIFY_MISMATCH_IN_AUDIO_DATA, - /**< The verify decoder detected a mismatch between the original - * audio signal and the decoded audio signal. - */ - - FLAC__STREAM_ENCODER_CLIENT_ERROR, - /**< One of the callbacks returned a fatal error. */ - - FLAC__STREAM_ENCODER_IO_ERROR, - /**< An I/O error occurred while opening/reading/writing a file. - * Check \c errno. - */ - - FLAC__STREAM_ENCODER_FRAMING_ERROR, - /**< An error occurred while writing the stream; usually, the - * write_callback returned an error. - */ - - FLAC__STREAM_ENCODER_MEMORY_ALLOCATION_ERROR - /**< Memory allocation failed. */ - -} FLAC__StreamEncoderState; - -/** Maps a FLAC__StreamEncoderState to a C string. - * - * Using a FLAC__StreamEncoderState as the index to this array - * will give the string equivalent.
