1991, 1999 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. - -[This is the first released version of the Lesser GPL. It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -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 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. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. 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 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. See the GNU - Lesser General Public License for more details. - - You should have received a copy of the GNU Lesser General Public - License along with this library; if not, write to the Free Software - Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA - -Also add information on how to contact you by electronic and paper mail. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the library, if -necessary.

Try mencoder/mplayer it might work. - -@section Why do I see a slight quality degradation with multithreaded MPEG* encoding ? - -For multithreaded MPEG* encoding, the encoded slices must be independent, -otherwise thread n would practically have to wait for n-1 to finish, so it's -quite logical that there is a small reduction of quality. This is not a bug. - -@section How can I read from the standard input or write to the standard output ? - -Use @file{-} as filename. - -@section Why does ffmpeg not decode audio in VOB files ? - -The audio is AC3 (a.k.a. A/52). AC3 decoding is an optional component in ffmpeg -as the component that handles AC3 decoding (liba52) is currently released under -the GPL. If you have liba52 installed on your system, enable AC3 decoding -with @code{./configure --enable-liba52 --enable-gpl}.

Please don't complain or -request more timely and/or frequent releases unless you are willing to -help out creating them. - -@section Why doesn't FFmpeg support feature [xyz]? - -Because no one has taken on that task yet. FFmpeg development is -driven by the tasks that are important to the individual developers. -If there is a feature that is important to you, the best way to get -it implemented is to undertake the task yourself. - - -@section Are there examples illustrating how to use the FFmpeg libraries, particularly libavcodec and libavformat ? - -Yes. Read the Developers Guide of the FFmpeg documentation. Alternatively, -examine the source code for one of the many open source projects that -already incorporate ffmpeg at (@url{projects.php}). - -@section Can you support my C compiler XXX ? - -It depends. If your compiler is C99-compliant, then patches to support -it are likely to be welcome if they do not pollute the source code -with @code{#ifdef}s related to the compiler. - -@section Visual C++ produces many errors. - -Visual C++ is not compliant to the C standard and does not support -the inline assembly used in FFmpeg. -If you wish - for whatever weird reason - to use Visual C++ for your -project then you can link the Visual C++ code with libav* as long as -you compile the latter with a working C compiler. For more information, see -the @emph{Visual C++ compatibility} section in the FFmpeg documentation. - -There have been efforts to make FFmpeg compatible with Visual C++ in the -past. However, they have all been rejected as too intrusive, especially -since MinGW does the job perfectly adequately. None of the core developers -work with Visual C++ and thus this item is low priority. Should you find -the silver bullet that solves this problem, feel free to shoot it at us. - -@section Can I use FFmpeg or libavcodec under Windows ? - -Yes, but the MinGW tools @emph{must} be used to compile FFmpeg. You -can link the resulting DLLs with any other Windows program. Read the -@emph{Native Windows Compilation} and @emph{Visual C++ compatibility} -sections in the FFmpeg documentation to find more information. - -To get help and instructions for using FFmpeg under Windows, check out -the FFmpeg Windows Help Forum at -@url{http://arrozcru.no-ip.org/ffmpeg/}. - -@section Can you add automake, libtool or autoconf support ? - -No. These tools are too bloated and they complicate the build. - -@section Why not rewrite ffmpeg in object-oriented C++ ? - -ffmpeg is already organized in a highly modular manner and does not need to -be rewritten in a formal object language. Further, many of the developers -favor straight C; it works for them. For more arguments on this matter, -read "Programming Religion" at (@url{http://www.tux.org/lkml/#s15}). - -@section Why are the ffmpeg programs devoid of debugging symbols ? - -The build process creates ffmpeg_g, ffplay_g, etc. which contain full debug -information. Those binaries are strip'd to create ffmpeg, ffplay, etc. If -you need the debug information, used the *_g versions. - -@section I do not like the LGPL, can I contribute code under the GPL instead ? - -Yes, as long as the code is optional and can easily and cleanly be placed -under #ifdef CONFIG_GPL without breaking anything. So for example a new codec -or filter would be OK under GPL while a bugfix to LGPL code would not. - -@section I want to compile xyz.c alone but my compiler produced many errors. - -Common code is in its own files in libav* and is used by the individual -codecs. They will not work without the common parts, you have to compile -the whole libav*. If you wish, disable some parts with configure switches. -You can also try to hack it and remove more, but if you had problems fixing -the compilation failure then you are probably not qualified for this. - -@section I have a file in memory / a API different from *open/*read/ libc how do i use it with libavformat ? - -You have to implement a URLProtocol, see libavformat/file.c in FFmpeg -and libmpdemux/demux_lavf.c in MPlayer sources. - -@section I get "No compatible shell script interpreter found." in MSys. - -The standard MSys bash (2.04) is broken.

This is especially true for RealVideo where -the Linux player does not seem to be very fast, so it can miss -frames. An example is: - -@example -ffmpeg -g 3 -r 3 -t 10 -b 50k -s qcif -f rv10 /tmp/b.rm -@end example - -@item The parameter 'q' which is displayed while encoding is the current -quantizer. The value 1 indicates that a very good quality could -be achieved. The value 31 indicates the worst quality. If q=31 appears -too often, it means that the encoder cannot compress enough to meet -your bitrate. You must either increase the bitrate, decrease the -frame rate or decrease the frame size. - -@item If your computer is not fast enough, you can speed up the -compression at the expense of the compression ratio. You can use -'-me zero' to speed up motion estimation, and '-intra' to disable -motion estimation completely (you have only I-frames, which means it -is about as good as JPEG compression). - -@item To have very low audio bitrates, reduce the sampling frequency -(down to 22050 kHz for MPEG audio, 22050 or 11025 for AC3). - -@item To have a constant quality (but a variable bitrate), use the option -'-qscale n' when 'n' is between 1 (excellent quality) and 31 (worst -quality). - -@item When converting video files, you can use the '-sameq' option which -uses the same quality factor in the encoder as in the decoder. -It allows almost lossless encoding. - -@end itemize - - -@chapter external libraries - -FFmpeg can be hooked up with a number of external libraries to add support -for more formats. - -@section AMR - -AMR comes in two different flavors, WB and NB.

-@subsection Native Windows compilation - -@itemize -@item Install the current versions of MSYS and MinGW from -@url{http://www.mingw.org/}. You can find detailed installation -instructions in the download section and the FAQ. - -NOTE: Use at least bash 3.1. Older versions are known to be failing on the -configure script. - -@item If you want to test the FFplay, also download -the MinGW development library of SDL 1.2.x -(@file{SDL-devel-1.2.x-mingw32.tar.gz}) from -@url{http://www.libsdl.org}. Unpack it in a temporary directory, and -unpack the archive @file{i386-mingw32msvc.tar.gz} in the MinGW tool -directory. Edit the @file{sdl-config} script so that it gives the -correct SDL directory when invoked. - -@item Extract the current version of FFmpeg. - -@item Start the MSYS shell (file @file{msys.bat}). - -@item Change to the FFmpeg directory and follow - the instructions of how to compile FFmpeg (file -@file{INSTALL}). Usually, launching @file{./configure} and @file{make} -suffices. If you have problems using SDL, verify that -@file{sdl-config} can be launched from the MSYS command line. - -@item You can install FFmpeg in @file{Program Files/FFmpeg} by typing -@file{make install}. Do not forget to copy @file{SDL.dll} to the place -you launch @file{ffplay} from. - -@end itemize - -Notes: -@itemize - -@item The target @file{make wininstaller} can be used to create a -Nullsoft based Windows installer for FFmpeg and FFplay. @file{SDL.dll} -must be copied to the FFmpeg directory in order to build the -installer. - -@item By using @code{./configure --enable-shared} when configuring FFmpeg, -you can build @file{avcodec.dll} and @file{avformat.dll}. With -@code{make install} you install the FFmpeg DLLs and the associated -headers in @file{Program Files/FFmpeg}. - -@item Visual C++ compatibility: If you used @code{./configure --enable-shared} -when configuring FFmpeg, FFmpeg tries to use the Microsoft Visual -C++ @code{lib} tool to build @code{avcodec.lib} and -@code{avformat.lib}. With these libraries you can link your Visual C++ -code directly with the FFmpeg DLLs (see below). - -@end itemize - -@subsection Visual C++ compatibility - -FFmpeg will not compile under Visual C++ -- and it has too many -dependencies on the GCC compiler to make a port viable. However, -if you want to use the FFmpeg libraries in your own applications, -you can still compile those applications using Visual C++. An -important restriction to this is that you have to use the -dynamically linked versions of the FFmpeg libraries (i.e. the -DLLs), and you have to make sure that Visual-C++-compatible -import libraries are created during the FFmpeg build process. - -This description of how to use the FFmpeg libraries with Visual C++ is -based on Visual C++ 2005 Express Edition Beta 2. If you have a different -version, you might have to modify the procedures slightly. - -Here are the step-by-step instructions for building the FFmpeg libraries -so they can be used with Visual C++: - -@enumerate - -@item Install Visual C++ (if you have not done so already). - -@item Install MinGW and MSYS as described above. - -@item Add a call to @file{vcvars32.bat} (which sets up the environment -variables for the Visual C++ tools) as the first line of -@file{msys.bat}. The standard location for @file{vcvars32.bat} is -@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat}, -and the standard location for @file{msys.bat} is -@file{C:\msys\1.0\msys.bat}. If this corresponds to your setup, add the -following line as the first line of @file{msys.bat}: - -@code{call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"} - -@item Start the MSYS shell (file @file{msys.bat}) and type @code{link.exe}. -If you get a help message with the command line options of @code{link.exe}, -this means your environment variables are set up correctly, the -Microsoft linker is on the path and will be used by FFmpeg to -create Visual-C++-compatible import libraries. - -@item Extract the current version of FFmpeg and change to the FFmpeg directory. - -@item Type the command -@code{./configure --enable-shared --disable-static --enable-memalign-hack} -to configure and, if that did not produce any errors, -type @code{make} to build FFmpeg. - -@item The subdirectories @file{libavformat}, @file{libavcodec}, and -@file{libavutil} should now contain the files @file{avformat.dll}, -@file{avformat.lib}, @file{avcodec.dll}, @file{avcodec.lib}, -@file{avutil.dll}, and @file{avutil.lib}, respectively. Copy the three -DLLs to your System32 directory (typically @file{C:\Windows\System32}). - -@end enumerate - -And here is how to use these libraries with Visual C++: - -@enumerate - -@item Create a new console application ("File / New / Project") and then -select "Win32 Console Application". On the appropriate page of the -Application Wizard, uncheck the "Precompiled headers" option. - -@item Write the source code for your application, or, for testing, just -copy the code from an existing sample application into the source file -that Visual C++ has already created for you. (Note that your source -filehas to have a @code{.cpp} extension; otherwise, Visual C++ will not -compile the FFmpeg headers correctly because in C mode, it does not -recognize the @code{inline} keyword.) For example, you can copy -@file{output_example.c} from the FFmpeg distribution (but you will -have to make minor modifications so the code will compile under -C++, see below). - -@item Open the "Project / Properties" dialog box. In the "Configuration" -combo box, select "All Configurations" so that the changes you make will -affect both debug and release builds. In the tree view on the left hand -side, select "C/C++ / General", then edit the "Additional Include -Directories" setting to contain the complete paths to the -@file{libavformat}, @file{libavcodec}, and @file{libavutil} -subdirectories of your FFmpeg directory. Note that the directories have -to be separated using semicolons. Now select "Linker / General" from the -tree view and edit the "Additional Library Directories" setting to -contain the same three directories. - -@item Still in the "Project / Properties" dialog box, select "Linker / Input" -from the tree view, then add the files @file{avformat.lib}, -@file{avcodec.lib}, and @file{avutil.lib} to the end of the "Additional -Dependencies". Note that the names of the libraries have to be separated -using spaces. - -@item Now, select "C/C++ / Code Generation" from the tree view. Select -"Debug" in the "Configuration" combo box. Make sure that "Runtime -Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in -the "Configuration" combo box and make sure that "Runtime Library" is -set to "Multi-threaded DLL". - -@item Click "OK" to close the "Project / Properties" dialog box and build -the application. Hopefully, it should compile and run cleanly. If you -used @file{output_example.c} as your sample application, you will get a -few compiler errors, but they are easy to fix. The first type of error -occurs because Visual C++ does not allow an @code{int} to be converted to -an @code{enum} without a cast. To solve the problem, insert the required -casts (this error occurs once for a @code{CodecID} and once for a -@code{CodecType}). The second type of error occurs because C++ requires -the return value of @code{malloc} to be cast to the exact type of the -pointer it is being assigned to. Visual C++ will complain that, for -example, @code{(void *)} is being assigned to @code{(uint8_t *)} without -an explicit cast. So insert an explicit cast in these places to silence -the compiler. The third type of error occurs because the @code{snprintf} -library function is called @code{_snprintf} under Visual C++. So just -add an underscore to fix the problem. With these changes, -@file{output_example.c} should compile under Visual C++, and the -resulting executable should produce valid video files. - -@end enumerate - -@subsection Cross compilation for Windows with Linux - -You must use the MinGW cross compilation tools available at -@url{http://www.mingw.org/}. - -Then configure FFmpeg with the following options: -@example -./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc- -@end example -(you can change the cross-prefix according to the prefix chosen for the -MinGW tools). - -Then you can easily test FFmpeg with Wine -(@url{http://www.winehq.com/}). - -@subsection Compilation under Cygwin - -Cygwin works very much like Unix. - -Just install your Cygwin with all the "Base" packages, plus the -following "Devel" ones: -@example -binutils, gcc-core, make, subversion -@end example - -Do not install binutils-20060709-1 (they are buggy on shared builds); -use binutils-20050610-1 instead. - -Then run - -@example -./configure --enable-static --disable-shared -@end example - -to make a static build or - -@example -./configure --enable-shared --disable-static -@end example - -to build shared libraries. - -If you want to build FFmpeg with additional libraries, download Cygwin -"Devel" packages for Ogg and Vorbis from any Cygwin packages repository -and/or SDL, xvid, faac, faad2 packages from Cygwin Ports, -(@url{http://cygwinports.dotsrc.org/}). - -@subsection Crosscompilation for Windows under Cygwin - -With Cygwin you can create Windows binaries that do not need the cygwin1.dll. - -Just install your Cygwin as explained before, plus these additional -"Devel" packages: -@example -gcc-mingw-core, mingw-runtime, mingw-zlib -@end example - -and add some special flags to your configure invocation. - -For a static build run -@example -./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin -@end example - -and for a build with shared libraries -@example -./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin -@end example - -@section BeOS - -The configure script should guess the configuration itself. -Networking support is currently not finished. -errno issues fixed by Andrew Bachmann. - -Old stuff: - -François Revol - revol at free dot fr - April 2002 - -The configure script should guess the configuration itself, -however I still did not test building on the net_server version of BeOS. - -FFserver is broken (needs poll() implementation). - -There are still issues with errno codes, which are negative in BeOS, and -that FFmpeg negates when returning.

(Meaning unfinished but - enabled code which breaks compilation or compiles but does not work or - breaks the regression tests) - You can commit unfinished stuff (for testing etc), but it must be disabled - (#ifdef etc) by default so it does not interfere with other developers' - work. -@item - You do not have to over-test things. If it works for you, and you think it - should work for others, then commit. If your code has problems - (portability, triggers compiler bugs, unusual environment etc) they will be - reported and eventually fixed. -@item - Do not commit unrelated changes together, split them into self-contained - pieces. Also do not forget that if part B depends on part A, but A does not - depend on B, then A can and should be committed first and separate from B. - Keeping changes well split into self-contained parts makes reviewing and - understanding them on the commit log mailing list easier. This also helps - in case of debugging later on. - Also if you have doubts about splitting or not splitting, do not hesitate to - ask/disscuss it on the developer mailing list. -@item - Do not change behavior of the program (renaming options etc) without - first discussing it on the ffmpeg-devel mailing list. Do not remove - functionality from the code. Just improve! - - Note: Redundant code can be removed. -@item - Do not commit changes to the build system (Makefiles, configure script) - which change behavior, defaults etc, without asking first. The same - applies to compiler warning fixes, trivial looking fixes and to code - maintained by other developers. We usually have a reason for doing things - the way we do. Send your changes as patches to the ffmpeg-devel mailing - list, and if the code maintainers say OK, you may commit. This does not - apply to files you wrote and/or maintain. -@item - We refuse source indentation and other cosmetic changes if they are mixed - with functional changes, such commits will be rejected and removed. Every - developer has his own indentation style, you should not change it. Of course - if you (re)write something, you can use your own style, even though we would - prefer if the indentation throughout FFmpeg was consistent (Many projects - force a given indentation style - we do not.). If you really need to make - indentation changes (try to avoid this), separate them strictly from real - changes. - - NOTE: If you had to put if()@{ .. @} over a large (> 5 lines) chunk of code, - then either do NOT change the indentation of the inner part within (do not - move it to the right)! or do so in a separate commit -@item - Always fill out the commit log message. Describe in a few lines what you - changed and why. You can refer to mailing list postings if you fix a - particular bug. Comments such as "fixed!" or "Changed it." are unacceptable. -@item - If you apply a patch by someone else, include the name and email address in - the log message. Since the ffmpeg-cvslog mailing list is publicly - archived you should add some SPAM protection to the email address. Send an - answer to ffmpeg-devel (or wherever you got the patch from) saying that - you applied the patch. -@item - Do NOT commit to code actively maintained by others without permission. - Send a patch to ffmpeg-devel instead. If noone answers within a reasonable - timeframe (12h for build failures and security fixes, 3 days small changes, - 1 week for big patches) then commit your patch if you think it is OK. - Also note, the maintainer can simply ask for more time to review! -@item - Subscribe to the ffmpeg-cvslog mailing list. The diffs of all commits - are sent there and reviewed by all the other developers. Bugs and possible - improvements or general questions regarding commits are discussed there. We - expect you to react if problems with your code are uncovered. -@item - Update the documentation if you change behavior or add features. If you are - unsure how best to do this, send a patch to ffmpeg-devel, the documentation - maintainer(s) will review and commit your stuff. -@item - Try to keep important discussions and requests (also) on the public - developer mailing list, so that all developers can benefit from them. -@item - Never write to unallocated memory, never write over the end of arrays, - always check values read from some untrusted source before using them - as array index or other risky things. -@item - Remember to check if you need to bump versions for the specific libav - parts (libavutil, libavcodec, libavformat) you are changing. You need - to change the version integer and the version string. - Incrementing the first component means no backward compatibility to - previous versions (e.g. removal of a function from the public API). - Incrementing the second component means backward compatible change - (e.g. addition of a function to the public API). - Incrementing the third component means a noteworthy binary compatible - change (e.g. encoder bug fix that matters for the decoder). -@item - If you add a new codec, remember to update the changelog, add it to - the supported codecs table in the documentation and bump the second - component of the @file{libavcodec} version number appropriately. If - it has a fourcc, add it to @file{libavformat/avienc.c}, even if it - is only a decoder. -@item - Do not change code to hide warnings without ensuring that the underlying - logic is correct and thus the warning was inappropriate. -@end enumerate - -We think our rules are not too hard. If you have comments, contact us. - -Note, these rules are mostly borrowed from the MPlayer project. - -@section Submitting patches - -First, (@pxref{Coding Rules}) above if you did not yet. - -When you submit your patch, try to send a unified diff (diff '-up' -option). I cannot read other diffs :-) - -Also please do not submit patches which contain several unrelated changes. -Split them into individual self-contained patches; this makes reviewing -them much easier. - -Run the regression tests before submitting a patch so that you can -verify that there are no big problems. - -Patches should be posted as base64 encoded attachments (or any other -encoding which ensures that the patch will not be trashed during -transmission) to the ffmpeg-devel mailing list, see -@url{http://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-devel} - -It also helps quite a bit if you tell us what the patch does (for example -'replaces lrint by lrintf'), and why (for example '*BSD isn't C99 compliant -and has no lrint()') - -@section Patch review process - -All patches posted to ffmpeg-devel will be reviewed, unless they contain a -clear note that the patch is not for SVN. -Reviews and comments will be posted as replies to the patch on the -mailing list. The patch submitter then has to take care of every comment, -that can be by resubmitting a changed patch or by disscussion. Resubmitted -patches will themselves be reviewed like any other patch. If at some point -a patch passes review with no comments then it is approved, that can for -simple and small patches happen immediately while large patches will generally -have to be changed and reviewed many times before they are approved. -After a patch is approved it will be committed to the repository. - -We will review all submitted patches, but sometimes we are quite busy so -especially for large patches this can take several weeks. - -When resubmitting patches, please do not make any significant changes -not related to the comments received during review. Such patches will -be rejected. Instead, submit significant changes or new features as -separate patches. - -@section Regression tests - -Before submitting a patch (or committing to the repository), you should at least -test that you did not break anything. - -The regression tests build a synthetic video stream and a synthetic -audio stream. These are then encoded and decoded with all codecs or -formats. The CRC (or MD5) of each generated file is recorded in a -result file. A 'diff' is launched to compare the reference results and -the result file. - -The regression tests then go on to test the FFserver code with a -limited set of streams. It is important that this step runs correctly -as well. - -Run 'make test' to test all the codecs and formats. - -Run 'make fulltest' to test all the codecs, formats and FFserver. - -[Of course, some patches may change the results of the regression tests.

On -my 667 Mhz tiBook (ppc7450), this means once every twenty *processor* -cycles. So we won't use that. - -The PMC are much more useful: not only can they report cycle-accurate -timing, but they can also be used to monitor many other parameters, -such as the number of AltiVec stalls for every kind of instruction, -or instruction cache misses. The downside is that not all processors -support the PMC (all G3, all G4 and the 970 do support them), and -they're inactive by default - you need to activate them with a -dedicated tool. Also, the number of available PMC depends on the -procesor: the various 604 have 2, the various 75x (aka. G3) have 4, -and the various 74xx (aka G4) have 6. - -*WARNING*: The PowerPC 970 is not very well documented, and its PMC -registers are 64 bits wide. To properly notify the code, you *must* -tune for the 970 (using --tune=970), or the code will assume 32 bit -registers. - - -II - Enabling FFmpeg PowerPC performance support - -This needs to be done by hand. First, you need to configure FFmpeg as -usual, but add the "--powerpc-perf-enable" option. For instance: - -##### -./configure --prefix=/usr/local/ffmpeg-svn --cc=gcc-3.3 --tune=7450 --powerpc-perf-enable -##### - -This will configure FFmpeg to install inside /usr/local/ffmpeg-svn, -compiling with gcc-3.3 (you should try to use this one or a newer -gcc), and tuning for the PowerPC 7450 (i.e. the newer G4; as a rule of -thumb, those at 550Mhz and more). It will also enable the PMC. - -You may also edit the file "config.h" to enable the following line: - -##### -// #define ALTIVEC_USE_REFERENCE_C_CODE 1 -##### - -If you enable this line, then the code will not make use of AltiVec, -but will use the reference C code instead. This is useful to compare -performance between two versions of the code. - -Also, the number of enabled PMC is defined in "libavcodec/ppc/dsputil_ppc.h": - -##### -#define POWERPC_NUM_PMC_ENABLED 4 -##### - -If you have a G4 CPU, you can enable all 6 PMC. DO NOT enable more -PMC than available on your CPU! - -Then, simply compile FFmpeg as usual (make && make install). - - - -III - Using FFmpeg PowerPC performance support - -This FFmeg can be used exactly as usual. But before exiting, FFmpeg -will dump a per-function report that looks like this: - -##### -PowerPC performance report - Values are from the PMC registers, and represent whatever the - registers are set to record. - Function "gmc1_altivec" (pmc1): - min: 231 - max: 1339867 - avg: 558.25 (255302) - Function "gmc1_altivec" (pmc2): - min: 93 - max: 2164 - avg: 267.31 (255302) - Function "gmc1_altivec" (pmc3): - min: 72 - max: 1987 - avg: 276.20 (255302) -(...) -##### - -In this example, PMC1 was set to record CPU cycles, PMC2 was set to -record AltiVec Permute Stall Cycles, and PMC3 was set to record AltiVec -Issue Stalls. - -The function "gmc1_altivec" was monitored 255302 times, and the -minimum execution time was 231 processor cycles.

It *really* helps to have installed LAME first. Then when -you run the ffserver ./configure, make sure that you have the --enable-mp3lame -flag turned on. - -LAME is important as it allows for streaming audio to Windows Media Player. -Don't ask why the other audio types do not work. - -As a simple test, just run the following two command lines (assuming that you -have a V4L video capture card): - -@example -./ffserver -f doc/ffserver.conf & -./ffmpeg http://localhost:8090/feed1.ffm -@end example - -At this point you should be able to go to your Windows machine and fire up -Windows Media Player (WMP).

Then install ffserver and ffmpeg, write a script to start -them up, and off you go. - -@section Troubleshooting - -@subsection I don't hear any audio, but video is fine. - -Maybe you didn't install LAME, or got your ./configure statement wrong. Check -the ffmpeg output to see if a line referring to MP3 is present. If not, then -your configuration was incorrect. If it is, then maybe your wiring is not -set up correctly. Maybe the sound card is not getting data from the right -input source. Maybe you have a really awful audio interface (like I do) -that only captures in stereo and also requires that one channel be flipped. -If you are one of these people, then export 'AUDIO_FLIP_LEFT=1' before -starting ffmpeg. - -@subsection The audio and video loose sync after a while. - -Yes, they do. - -@subsection After a long while, the video update rate goes way down in WMP. - -Yes, it does. Who knows why? - -@subsection WMP 6.4 behaves differently to WMP 7. - -Yes, it does. Any thoughts on this would be gratefully received. These -differences extend to embedding WMP into a web page. [There are two -object IDs that you can use: The old one, which does not play well, and -the new one, which does (both tested on the same system). However, -I suspect that the new one is not available unless you have installed WMP 7]. - -@section What else can it do? - -You can replay video from .ffm files that was recorded earlier. -However, there are a number of caveats, including the fact that the -ffserver parameters must match the original parameters used to record the -file. If they do not, then ffserver deletes the file before recording into it. -(Now that I write this, it seems broken). - -You can fiddle with many of the codec choices and encoding parameters, and -there are a bunch more parameters that you cannot control. Post a message -to the mailing list if there are some 'must have' parameters. Look in -ffserver.conf for a list of the currently available controls. - -It will automatically generate the ASX or RAM files that are often used -in browsers. These files are actually redirections to the underlying ASF -or RM file. The reason for this is that the browser often fetches the -entire file before starting up the external viewer. The redirection files -are very small and can be transferred quickly. [The stream itself is -often 'infinite' and thus the browser tries to download it and never -finishes.] - -@section Tips - -* When you connect to a live stream, most players (WMP, RA, etc) want to -buffer a certain number of seconds of material so that they can display the -signal continuously. However, ffserver (by default) starts sending data -in realtime. This means that there is a pause of a few seconds while the -buffering is being done by the player. The good news is that this can be -cured by adding a '?buffer=5' to the end of the URL. This means that the -stream should start 5 seconds in the past -- and so the first 5 seconds -of the stream are sent as fast as the network will allow. It will then -slow down to real time. This noticeably improves the startup experience. - -You can also add a 'Preroll 15' statement into the ffserver.conf that will -add the 15 second prebuffering on all requests that do not otherwise -specify a time. In addition, ffserver will skip frames until a key_frame -is found. This further reduces the startup delay by not transferring data -that will be discarded. - -* You may want to adjust the MaxBandwidth in the ffserver.conf to limit -the amount of bandwidth consumed by live streams. - -@section Why does the ?buffer / Preroll stop working after a time? - -It turns out that (on my machine at least) the number of frames successfully -grabbed is marginally less than the number that ought to be grabbed. This -means that the timestamp in the encoded data stream gets behind realtime. -This means that if you say 'Preroll 10', then when the stream gets 10 -or more seconds behind, there is no Preroll left. - -Fixing this requires a change in the internals of how timestamps are -handled. - -@section Does the @code{?date=} stuff work. - -Yes (subject to the limitation outlined above). Also note that whenever you -start ffserver, it deletes the ffm file (if any parameters have changed), -thus wiping out what you had recorded before. - -The format of the @code{?date=xxxxxx} is fairly flexible. You should use one -of the following formats (the 'T' is literal): - -@example -* YYYY-MM-DDTHH:MM:SS (localtime) -* YYYY-MM-DDTHH:MM:SSZ (UTC) -@end example - -You can omit the YYYY-MM-DD, and then it refers to the current day. However -note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this -may be in the future and so is unlikely to be useful. - -You use this by adding the ?date= to the end of the URL for the stream. -For example: @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}. - -@chapter Invocation -@section Syntax -@example -@c man begin SYNOPSIS -ffserver [options] -@c man end -@end example - -@section Options -@c man begin OPTIONS -@table @option -@item -L -Print the license. -@item -h -Print the help. -@item -f configfile -Use @file{configfile} instead of @file{/etc/ffserver.conf}. -@end table -@c man end - -@ignore - -@setfilename ffsserver -@settitle FFserver video server - -@c man begin SEEALSO -ffmpeg(1), ffplay(1), the @file{ffmpeg/doc/ffserver.conf} example and -the HTML documentation of @file{ffmpeg}. -@c man end - -@c man begin AUTHOR -Fabrice Bellard -@c man end - -@end ignore - -@bye diff --git a/contrib/ffmpeg/doc/ffserver.conf b/contrib/ffmpeg/doc/ffserver.conf deleted file mode 100644 index a3b3ff412..000000000 --- a/contrib/ffmpeg/doc/ffserver.conf +++ /dev/null @@ -1,349 +0,0 @@ -# Port on which the server is listening.

multi-channel capability, a down matrix from 5, 4, or 3 channel to Lt Rt may be desirable. In the case when the number of decoded audio channels exceeds 5, 4 or 3 respectively a first stage down mix to 5, 4 or 3 chs should be used as described above. - -The down matrixing equations for 5-channel source audio to a two-channel Lt Rt playback system are given by: - -Left left+0.7*center-0.7*(lt surround+rt surround) - -Right=right+0.7*center+0.7*(lt surround+rt surround) - -Embedded mixing to 2-channel - -One concern arising from the proliferation of multi-channel audio systems is that most home systems presently have only two channel playback capability. To accommodate this a fixed 2-channel down matrix processes is commonly used following the multi-channel decoding stage. However, for music only applications the image quality etc. of the down matrixed signal may not match that of an equivalent stereo recording found on CD. - -The concept of embedded mixing is to allow the producer to dynamically specify the matrixing coefficients within the audio frame itself. In this way the stereo down mix at the decoder may be better matched to a 2-channel playback environment. - -CHS*2, 7-bit down mix indexes (MCOEFFS) are transmitted along with the multi-channel audio once in every frame. The indexes are converted to attenuation factors using a 7 bit LUT. The 2-ch down mix equations are as follows, - -Left Ch=sum (MCOEFF[n]*Ch[n]) for n=1, CHS - -Right Ch sum (MCOEFF[n+CHS]*Ch[n]) for n=1, CHS - -where Ch(n) represents the subband samples in the (n)th audio channel. - - -*/ diff --git a/contrib/ffmpeg/libavcodec/dcahuff.h b/contrib/ffmpeg/libavcodec/dcahuff.h deleted file mode 100644 index 8a78aee7e..000000000 --- a/contrib/ffmpeg/libavcodec/dcahuff.h +++ /dev/null @@ -1,1068 +0,0 @@ -/* - * DCA compatible decoder - huffman tables - * Copyright (C) 2004 Gildas Bazin - * Copyright (C) 2007 Konstantin Shishkov - * - * This file is part of FFmpeg. - * - * FFmpeg 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. - * - * FFmpeg 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.

The VQHD header - * is laid out as: - * - * bytes 0-3 chunk fourcc: 'VQHD' - * bytes 4-7 chunk size in big-endian format, should be 0x0000002A - * bytes 8-49 VQHD chunk data - * - * Bytes 8-49 are what this decoder expects to see. - * - * Briefly, VQA is a vector quantized animation format that operates in a - * VGA palettized colorspace. It operates on pixel vectors (blocks) - * of either 4x2 or 4x4 in size. Compressed VQA chunks can contain vector - * codebooks, palette information, and code maps for rendering vectors onto - * frames. Any of these components can also be compressed with a run-length - * encoding (RLE) algorithm commonly referred to as "format80". - * - * VQA takes a novel approach to rate control. Each group of n frames - * (usually, n = 8) relies on a different vector codebook. Rather than - * transporting an entire codebook every 8th frame, the new codebook is - * broken up into 8 pieces and sent along with the compressed video chunks - * for each of the 8 frames preceding the 8 frames which require the - * codebook. A full codebook is also sent on the very first frame of a - * file. This is an interesting technique, although it makes random file - * seeking difficult despite the fact that the frames are all intracoded. - * - * V1,2 VQA uses 12-bit codebook indices. If the 12-bit indices were - * packed into bytes and then RLE compressed, bytewise, the results would - * be poor. That is why the coding method divides each index into 2 parts, - * the top 4 bits and the bottom 8 bits, then RL encodes the 4-bit pieces - * together and the 8-bit pieces together. If most of the vectors are - * clustered into one group of 256 vectors, most of the 4-bit index pieces - * should be the same. - */ - -#include -#include -#include -#include - -#include "common.h" -#include "avcodec.h" -#include "dsputil.h" - -#define PALETTE_COUNT 256 -#define VQA_HEADER_SIZE 0x2A -#define CHUNK_PREAMBLE_SIZE 8 - -/* allocate the maximum vector space, regardless of the file version: - * (0xFF00 codebook vectors + 0x100 solid pixel vectors) * (4x4 pixels/block) */ -#define MAX_CODEBOOK_VECTORS 0xFF00 -#define SOLID_PIXEL_VECTORS 0x100 -#define MAX_VECTORS (MAX_CODEBOOK_VECTORS + SOLID_PIXEL_VECTORS) -#define MAX_CODEBOOK_SIZE (MAX_VECTORS * 4 * 4) - -#define CBF0_TAG MKBETAG('C', 'B', 'F', '0') -#define CBFZ_TAG MKBETAG('C', 'B', 'F', 'Z') -#define CBP0_TAG MKBETAG('C', 'B', 'P', '0') -#define CBPZ_TAG MKBETAG('C', 'B', 'P', 'Z') -#define CPL0_TAG MKBETAG('C', 'P', 'L', '0') -#define CPLZ_TAG MKBETAG('C', 'P', 'L', 'Z') -#define VPTZ_TAG MKBETAG('V', 'P', 'T', 'Z') - -#define VQA_DEBUG 0 - -#if VQA_DEBUG -#define vqa_debug printf -#else -static inline void vqa_debug(const char *format, ...) { } -#endif - -typedef struct VqaContext { - - AVCodecContext *avctx;

The FD may be set for non-blocking I/O, - in which case you can use select() or poll() to wait for output - buffer space. - - To set the DV output parameters (e.g. whether you want NTSC or PAL - video), use the DV1394_INIT ioctl, passing in the parameters you - want in a struct dv1394_init. - - Example 1: - To play a raw .DV file: cat foo.DV > /dev/dv1394 - (cat will use write() internally) - - Example 2: - static struct dv1394_init init = { - 0x63, (broadcast channel) - 4, (four-frame ringbuffer) - DV1394_NTSC, (send NTSC video) - 0, 0 (default empty packet rate) - } - - ioctl(fd, DV1394_INIT, &init); - - while(1) { - read( , buf, DV1394_NTSC_FRAME_SIZE ); - write( , buf, DV1394_NTSC_FRAME_SIZE ); - } - - 2) - - For more control over buffering, and to avoid unnecessary copies - of the DV data, you can use the more sophisticated the mmap() interface. - First, call the DV1394_INIT ioctl to specify your parameters, - including the number of frames in the ringbuffer. Then, calling mmap() - on the dv1394 device will give you direct access to the ringbuffer - from which the DV card reads your frame data. - - The ringbuffer is simply one large, contiguous region of memory - containing two or more frames of packed DV data. Each frame of DV data - is 120000 bytes (NTSC) or 144000 bytes (PAL). - - Fill one or more frames in the ringbuffer, then use the DV1394_SUBMIT_FRAMES - ioctl to begin I/O. You can use either the DV1394_WAIT_FRAMES ioctl - or select()/poll() to wait until the frames are transmitted. Next, you'll - need to call the DV1394_GET_STATUS ioctl to determine which ringbuffer - frames are clear (ready to be filled with new DV data). Finally, use - DV1394_SUBMIT_FRAMES again to send the new data to the DV output. - - - Example: here is what a four-frame ringbuffer might look like - during DV transmission: - - - frame 0 frame 1 frame 2 frame 3 - - *--------------------------------------* - | CLEAR | DV data | DV data | CLEAR | - *--------------------------------------* - - - transmission goes in this direction --->>> - - - The DV hardware is currently transmitting the data in frame 1. - Once frame 1 is finished, it will automatically transmit frame 2. - (if frame 2 finishes before frame 3 is submitted, the device - will continue to transmit frame 2, and will increase the dropped_frames - counter each time it repeats the transmission). - - - If you called DV1394_GET_STATUS at this instant, you would - receive the following values: - - n_frames = 4 - active_frame = 1 - first_clear_frame = 3 - n_clear_frames = 2 - - At this point, you should write new DV data into frame 3 and optionally - frame 0. Then call DV1394_SUBMIT_FRAMES to inform the device that - it may transmit the new frames. - - ERROR HANDLING - - An error (buffer underflow/overflow or a break in the DV stream due - to a 1394 bus reset) can be detected by checking the dropped_frames - field of struct dv1394_status (obtained through the - DV1394_GET_STATUS ioctl). - - The best way to recover from such an error is to re-initialize - dv1394, either by using the DV1394_INIT ioctl call, or closing the - file descriptor and opening it again. (note that you must unmap all - ringbuffer mappings when closing the file descriptor, or else - dv1394 will still be considered 'in use'). - - MAIN LOOP - - For maximum efficiency and robustness against bus errors, you are - advised to model the main loop of your application after the - following pseudo-code example: - - (checks of system call return values omitted for brevity; always - check return values in your code!) - - while( frames left ) { - - struct pollfd *pfd = ...; - - pfd->fd = dv1394_fd; - pfd->revents = 0; - pfd->events = POLLOUT | POLLIN; (OUT for transmit, IN for receive) - - (add other sources of I/O here) - - poll(pfd, 1, -1); (or select(); add a timeout if you want) - - if(pfd->revents) { - struct dv1394_status status; - - ioctl(dv1394_fd, DV1394_GET_STATUS, &status); - - if(status.dropped_frames > 0) { - reset_dv1394(); - } else { - for(int i = 0; i < status.n_clear_frames; i++) { - copy_DV_frame(); - } - } - } - } - - where copy_DV_frame() reads or writes on the dv1394 file descriptor - (read/write mode) or copies data to/from the mmap ringbuffer and - then calls ioctl(DV1394_SUBMIT_FRAMES) to notify dv1394 that new - frames are availble (mmap mode). - - reset_dv1394() is called in the event of a buffer - underflow/overflow or a halt in the DV stream (e.g. due to a 1394 - bus reset). To guarantee recovery from the error, this function - should close the dv1394 file descriptor (and munmap() all - ringbuffer mappings, if you are using them), then re-open the - dv1394 device (and re-map the ringbuffer). - -*/ - - -/* maximum number of frames in the ringbuffer */ -#define DV1394_MAX_FRAMES 32 - -/* number of *full* isochronous packets per DV frame */ -#define DV1394_NTSC_PACKETS_PER_FRAME 250 -#define DV1394_PAL_PACKETS_PER_FRAME 300 - -/* size of one frame's worth of DV data, in bytes */ -#define DV1394_NTSC_FRAME_SIZE (480 * DV1394_NTSC_PACKETS_PER_FRAME) -#define DV1394_PAL_FRAME_SIZE (480 * DV1394_PAL_PACKETS_PER_FRAME) - - -/* ioctl() commands */ - -enum { - /* I don't like using 0 as a valid ioctl() */ - DV1394_INVALID = 0, - - - /* get the driver ready to transmit video. - pass a struct dv1394_init* as the parameter (see below), - or NULL to get default parameters */ - DV1394_INIT, - - - /* stop transmitting video and free the ringbuffer */ - DV1394_SHUTDOWN, - - - /* submit N new frames to be transmitted, where - the index of the first new frame is first_clear_buffer, - and the index of the last new frame is - (first_clear_buffer + N) % n_frames */ - DV1394_SUBMIT_FRAMES, - - - /* block until N buffers are clear (pass N as the parameter) - Because we re-transmit the last frame on underrun, there - will at most be n_frames - 1 clear frames at any time */ - DV1394_WAIT_FRAMES, - - /* capture new frames that have been received, where - the index of the first new frame is first_clear_buffer, - and the index of the last new frame is - (first_clear_buffer + N) % n_frames */ - DV1394_RECEIVE_FRAMES, - - - DV1394_START_RECEIVE, - - - /* pass a struct dv1394_status* as the parameter (see below) */ - DV1394_GET_STATUS, -}; - - - -enum pal_or_ntsc { - DV1394_NTSC = 0, - DV1394_PAL -}; - - - - -/* this is the argument to DV1394_INIT */ -struct dv1394_init { - /* DV1394_API_VERSION */ - unsigned int api_version; - - /* isochronous transmission channel to use */ - unsigned int channel; - - /* number of frames in the ringbuffer.

If the dv1394 driver produces empty packets at - a rate that your device does not accept, you may see ugly patterns on the - DV output, or even no output at all. - - The default empty packet insertion rate seems to work for many people; if - your DV output is stable, you can simply ignore this discussion. However, - we have exposed the empty packet rate as a parameter to support devices that - do not work with the default rate. - - The decision to insert an empty packet is made with a numerator/denominator - algorithm.

Here are some notes - * for anyone trying to understand the technical details of this format: - * - * The format has no definite file signature. This is problematic for a - * general-purpose media player that wants to automatically detect file - * types. However, a CIN file does start with 5 32-bit numbers that - * specify audio and video parameters. This demuxer gets around the lack - * of file signature by performing sanity checks on those parameters. - * Probabalistically, this is a reasonable solution since the number of - * valid combinations of the 5 parameters is a very small subset of the - * total 160-bit number space. - * - * Refer to the function idcin_probe() for the precise A/V parameters - * that this demuxer allows. - * - * Next, each audio and video frame has a duration of 1/14 sec. If the - * audio sample rate is a multiple of the common frequency 22050 Hz it will - * divide evenly by 14. However, if the sample rate is 11025 Hz: - * 11025 (samples/sec) / 14 (frames/sec) = 787.5 (samples/frame) - * The way the CIN stores audio in this case is by storing 787 sample - * frames in the first audio frame and 788 sample frames in the second - * audio frame. Therefore, the total number of bytes in an audio frame - * is given as: - * audio frame #0: 787 * (bytes/sample) * (# channels) bytes in frame - * audio frame #1: 788 * (bytes/sample) * (# channels) bytes in frame - * audio frame #2: 787 * (bytes/sample) * (# channels) bytes in frame - * audio frame #3: 788 * (bytes/sample) * (# channels) bytes in frame - * - * Finally, not all Id CIN creation tools agree on the resolution of the - * color palette, apparently. Some creation tools specify red, green, and - * blue palette components in terms of 6-bit VGA color DAC values which - * range from 0..63. Other tools specify the RGB components as full 8-bit - * values that range from 0..255.
