From 0ea721f7ce81357bc4ec6eea609cd50482c3d15b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Diego=20=27Flameeyes=27=20Petten=C3=B2?= Date: Sat, 2 Dec 2006 01:19:48 +0000 Subject: Start working on a branch where FFmpeg is not copied, patched and carved to be built with automake but instead imported inline and built using its own build system. This is an import of a slightly modified FFmpeg current tree. xine-lib builds, install and run fine with it, but there are of course plenty of things that needs to be fixed before it can even be considered for a 1.2.x series. Work will continue in the next days of course.

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.

Use "mjpeg" instead. + +@section FFmpeg does not support codec XXX. Can you include a Windows DLL loader to support it ? + +No. FFmpeg only supports open source codecs. Windows DLLs are not +portable, bloated and often slow. + +@section I get "Unsupported codec (id=86043) for input stream #0.1". What is the problem ? + +This is the Qcelp codec, FFmpeg has no support for that codec currently. 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-a52}. Take care: by +enabling AC3, you automatically change the license of libavcodec from +LGPL to GPL. + +@section Which codecs are supported by Windows ? + +Windows does not support standard formats like MPEG very well, unless you +install some additional codecs + +The following list of video codecs should work on most Windows systems: +@table @option +@item msmpeg4v2 +.avi/.asf +@item msmpeg4 +.asf only +@item wmv1 +.asf only +@item wmv2 +.asf only +@item mpeg4 +only if you have some MPEG-4 codec installed like ffdshow or XviD +@item mpeg1 +.mpg only +@end table +Note, ASF files often have .wmv or .wma extensions in Windows.

For 2.4.26 there is a patch at +(@url{http://mplayerhq.hu/~michael/bttv-420-2.4.26.patch}). This may also +apply cleanly to other 2.4-series kernels. + +@section How do I avoid the ugly aliasing artifacts in bt8x8 captures on Linux? + +Pass 'combfilter=1 lumafilter=1' to the bttv driver. Note though that 'combfilter=1' +will cause somewhat too strong filtering. A fix is to apply (@url{http://mplayerhq.hu/~michael/bttv-comb-2.4.26.patch}) +or (@url{http://mplayerhq.hu/~michael/bttv-comb-2.6.6.patch}) +and pass 'combfilter=2'. + +@section I have a problem with an old version of ffmpeg; where should I report it? +Nowhere. Upgrade to the latest release or if there is no recent release upgrade +to Subversion HEAD. You could also try to report it. Maybe you will get lucky and +become the first person in history to get an answer different from "upgrade +to Subversion HEAD". + +@section -f jpeg doesn't work. + +Try '-f image2 test%d.jpg'. + +@section Why can I not change the framerate? + +Some codecs, like MPEG-1/2, only allow a small number of fixed framerates. +Choose a different codec with the -vcodec command line option. + +@section ffmpeg does not work; What is wrong? + +Try a 'make distclean' in the ffmpeg source directory. If this does not help see +(@url{http://ffmpeg.org/bugreports.php}). + +@section How do I encode XviD or DivX video with ffmpeg? + +Both XviD and DivX (version 4+) are implementations of the ISO MPEG-4 +standard (note that there are many other coding formats that use this +same standard). Thus, use '-vcodec mpeg4' to encode these formats. The +default fourcc stored in an MPEG-4-coded file will be 'FMP4'. If you want +a different fourcc, use the '-vtag' option. E.g., '-vtag xvid' will +force the fourcc 'xvid' to be stored as the video fourcc rather than the +default. + +@section How do I encode videos which play on the iPod? + +@table @option +@item needed stuff +-acodec aac -vcodec mpeg4 width<=320 height<=240 +@item working stuff +4mv, title +@item non-working stuff +B-frames +@item example command line +ffmpeg -i input -acodec aac -ab 128 -vcodec mpeg4 -b 1200kb -mbd 2 -flags +4mv+trell -aic 2 -cmp 2 -subcmp 2 -s 320x180 -title X output.mp4 +@end table + +@section How do I encode videos which play on the PSP? + +@table @option +@item needed stuff +-acodec aac -vcodec mpeg4 width*height<=76800 width%16=0 height%16=0 -ar 24000 -r 30000/1001 or 15000/1001 -f psp +@item working stuff +4mv, title +@item non-working stuff +B-frames +@item example command line +ffmpeg -i input -acodec aac -ab 128 -vcodec mpeg4 -b 1200kb -ar 24000 -mbd 2 -flags +4mv+trell -aic 2 -cmp 2 -subcmp 2 -s 368x192 -r 30000/1001 -title X -f psp output.mp4 +@item needed stuff for H.264 +-acodec aac -vcodec h264 width*height<=76800 width%16=0? height%16=0? -ar 48000 -coder 1 -r 30000/1001 or 15000/1001 -f psp +@item working stuff for H.264 +title, loop filter +@item non-working stuff for H.264 +CAVLC +@item example command line +ffmpeg -i input -acodec aac -ab 128 -vcodec h264 -b 1200kb -ar 48000 -mbd 2 -coder 1 -cmp 2 -subcmp 2 -s 368x192 -r 30000/1001 -title X -f psp -flags loop -trellis 2 -partitions parti4x4+parti8x8+partp4x4+partp8x8+partb8x8 output.mp4 +@end table + +@section How can I read DirectShow files? + +If you have built FFmpeg with @code{./configure --enable-avisynth} +(only possible on MinGW/Cygwin platforms), +then you may use any file that DirectShow can read as input. +(Be aware that this feature has been recently added, +so you will need to help yourself in case of problems.) + +Just create an "input.avs" text file with this single line ... +@example + DirectShowSource("C:\path to your file\yourfile.asf") +@end example +... and then feed that text file to FFmpeg: +@example + ffmpeg -i input.avs +@end example + +For ANY other help on Avisynth, please visit @url{http://www.avisynth.org/}. + +@chapter Development + +@section When will the next FFmpeg version be released? / Why are FFmpeg releases so few and far between? + +Like most open source projects FFmpeg suffers from a certain lack of +manpower. For this reason the developers have to prioritize the work +they do and putting out releases is not at the top of the list, fixing +bugs and reviewing patches takes precedence. 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 ? + +No. Only GCC is supported. GCC is ported to most systems available and there +is no need to pollute the source code with @code{#ifdef}s +related to the compiler. + +@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. + +@section Can you add automake, libtool or autoconf support ? + +No. These tools are too bloated and they complicate the build. Moreover, +since only @samp{gcc} is supported they would add little advantages in +terms of portability. + +@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://lkml.org/faq/lkmlfaq-15.html}). + +@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 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 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.

It can also grab from +a live audio/video source. + +The command line interface is designed to be intuitive, in the sense +that FFmpeg tries to figure out all parameters that can possibly be +derived automatically.

They are +raw files, without header. They can be generated by all decent video +decoders. You must specify the size of the image with the @option{-s} option +if FFmpeg cannot guess it. + +* You can input from a raw YUV420P file: + +@example +ffmpeg -i /tmp/test.yuv /tmp/out.avi +@end example + +test.yuv is a file containing raw YUV planar data. Each frame is composed +of the Y plane followed by the U and V planes at half vertical and +horizontal resolution. + +* You can output to a raw YUV420P file: + +@example +ffmpeg -i mydivx.avi hugefile.yuv +@end example + +* You can set several input files and output files: + +@example +ffmpeg -i /tmp/a.wav -s 640x480 -i /tmp/a.yuv /tmp/a.mpg +@end example + +Converts the audio file a.wav and the raw YUV video file a.yuv +to MPEG file a.mpg. + +* You can also do audio and video conversions at the same time: + +@example +ffmpeg -i /tmp/a.wav -ar 22050 /tmp/a.mp2 +@end example + +Converts a.wav to MPEG audio at 22050Hz sample rate. + +* You can encode to several formats at the same time and define a +mapping from input stream to output streams: + +@example +ffmpeg -i /tmp/a.wav -ab 64 /tmp/a.mp2 -ab 128 /tmp/b.mp2 -map 0:0 -map 0:0 +@end example + +Converts a.wav to a.mp2 at 64 kbits and to b.mp2 at 128 kbits. '-map +file:index' specifies which input stream is used for each output +stream, in the order of the definition of output streams. + +* You can transcode decrypted VOBs + +@example +ffmpeg -i snatch_1.vob -f avi -vcodec mpeg4 -b 800k -g 300 -bf 2 -acodec mp3 -ab 128 snatch.avi +@end example + +This is a typical DVD ripping example; the input is a VOB file, the +output an AVI file with MPEG-4 video and MP3 audio. Note that in this +command we use B-frames so the MPEG-4 stream is DivX5 compatible, and +GOP size is 300 which means one intra frame every 10 seconds for 29.97fps +input video.

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.

+FFmpeg should be compiled with at least GCC 2.95.3. GCC 3.2 is the +preferred compiler now for FFmpeg. All future optimizations will depend on +features only found in GCC 3.2. + +@section BSD + +BSD make will not build FFmpeg, you need to install and use GNU Make +(@file{gmake}). + +@section Windows + +@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. + +@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}. Don't 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 haven't 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 didn't 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++ won't +compile the FFmpeg headers correctly because in C mode, it doesn't +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++ doesn't 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 --enable-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 don't 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 --enable-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 --enable-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 didn't 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. This ends up turning errors into +valid results, then crashes. +(To be fixed) + +@chapter Developers Guide + +@section API +@itemize @bullet +@item libavcodec is the library containing the codecs (both encoding and +decoding). Look at @file{libavcodec/apiexample.c} to see how to use it. + +@item libavformat is the library containing the file format handling (mux and +demux code for several formats). Look at @file{ffplay.c} to use it in a +player. See @file{output_example.c} to use it to generate audio or video +streams. + +@end itemize + +@section Integrating libavcodec or libavformat in your program + +You can integrate all the source code of the libraries to link them +statically to avoid any version problem. All you need is to provide a +'config.mak' and a 'config.h' in the parent directory. See the defines +generated by ./configure to understand what is needed. + +You can use libavcodec or libavformat in your commercial program, but +@emph{any patch you make must be published}. The best way to proceed is +to send your patches to the FFmpeg mailing list. + +@node Coding Rules +@section Coding Rules + +FFmpeg is programmed in the ISO C90 language with a few additional +features from ISO C99, namely: +@itemize @bullet +@item +the @samp{inline} keyword; +@item +@samp{//} comments; +@item +designated struct initializers (@samp{struct s x = @{ .i = 17 @};}) +@item +compound literals (@samp{x = (struct s) @{ 17, 23 @};}) +@end itemize + +These features are supported by all compilers we care about, so we won't +accept patches to remove their use unless they absolutely don't impair +clarity and performance. + +All code must compile with GCC 2.95 and GCC 3.3. Currently, FFmpeg also +compiles with several other compilers, such as the Compaq ccc compiler +or Sun Studio 9, and we would like to keep it that way unless it would +be exceedingly involved. To ensure compatibility, please don't use any +additional C99 features or GCC extensions. Especially watch out for: +@itemize @bullet +@item +mixing statements and declarations; +@item +@samp{long long} (use @samp{int64_t} instead); +@item +@samp{__attribute__} not protected by @samp{#ifdef __GNUC__} or similar; +@item +GCC statement expressions (@samp{(x = (@{ int y = 4; y; @})}). +@end itemize + +Indent size is 4. +The presentation is the one specified by 'indent -i4 -kr -nut'. +The TAB character is forbidden outside of Makefiles as is any +form of trailing whitespace. Commits containing either will be +rejected by the Subversion repository. + +Main priority in FFmpeg is simplicity and small code size (=less +bugs). + +Comments: Use the JavaDoc/Doxygen +format (see examples below) so that code documentation +can be generated automatically. All nontrivial functions should have a comment +above them explaining what the function does, even if it's just one sentence. +All structures and their member variables should be documented, too. +@example +/** + * @@file mpeg.c + * MPEG codec. + * @@author ... + */ + +/** + * Summary sentence. + * more text ... + * ... + */ +typedef struct Foobar@{ + int var1; /**< var1 description */ + int var2; ///< var2 description + /** var3 description */ + int var3; +@} Foobar; + +/** + * Summary sentence. + * more text ... + * ... + * @@param my_parameter description of my_parameter + * @@return return value description + */ +int myfunc(int my_parameter) +... +@end example + +fprintf and printf are forbidden in libavformat and libavcodec, +please use av_log() instead. + +@section Development Policy + +@enumerate +@item + You must not commit code which breaks FFmpeg! (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 don't 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. +@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 don't.). 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 (don't + 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's 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 + 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. +@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 didn't 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 won't 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()') + +We reply to all submitted patches and either apply or reject with some +explanation why, but sometimes we are quite busy so it can take a week or two. + +@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. In +this case, the reference results of the regression tests shall be modified +accordingly]. + +@bye diff --git a/contrib/ffmpeg/doc/ffmpeg_powerpc_performance_evaluation_howto.txt b/contrib/ffmpeg/doc/ffmpeg_powerpc_performance_evaluation_howto.txt new file mode 100644 index 000000000..2eb4ee71a --- /dev/null +++ b/contrib/ffmpeg/doc/ffmpeg_powerpc_performance_evaluation_howto.txt @@ -0,0 +1,172 @@ +FFmpeg & evaluating performance on the PowerPC Architecture HOWTO + +(c) 2003-2004 Romain Dolbeau + + + +I - Introduction + +The PowerPC architecture and its SIMD extension AltiVec offer some +interesting tools to evaluate performance and improve the code. +This document tries to explain how to use those tools with FFmpeg. + +The architecture itself offers two ways to evaluate the performance of +a given piece of code: + +1) The Time Base Registers (TBL) +2) The Performance Monitor Counter Registers (PMC) + +The first ones are always available, always active, but they're not very +accurate: the registers increment by one every four *bus* cycles. 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. The max and average +aren't much use, as it's very likely the OS interrupted execution for +reasons of its own :-( + +With the exact same settings and source file, but using the reference C +code we get: + +##### +PowerPC performance report + Values are from the PMC registers, and represent whatever the + registers are set to record. + Function "gmc1_altivec" (pmc1): + min: 592 + max: 2532235 + avg: 962.88 (255302) + Function "gmc1_altivec" (pmc2): + min: 0 + max: 33 + avg: 0.00 (255302) + Function "gmc1_altivec" (pmc3): + min: 0 + max: 350 + avg: 0.03 (255302) +(...) +##### + +592 cycles, so the fastest AltiVec execution is about 2.5x faster than +the fastest C execution in this example. It's not perfect but it's not +bad (well I wrote this function so I can't say otherwise :-). + +Once you have that kind of report, you can try to improve things by +finding what goes wrong and fixing it; in the example above, one +should try to diminish the number of AltiVec stalls, as this *may* +improve performance. + + + +IV) Enabling the PMC in Mac OS X + +This is easy. Use "Monster" and "monster". Those tools come from +Apple's CHUD package, and can be found hidden in the developer web +site & FTP site. "MONster" is the graphical application, use it to +generate a config file specifying what each register should +monitor. Then use the command-line application "monster" to use that +config file, and enjoy the results. + +Note that "MONster" can be used for many other things, but it's +documented by Apple, it's not my subject. + +If you are using CHUD 4.4.2 or later, you'll notice that MONster is +no longer available. It's been superseeded by Shark, where +configuration of PMCs is available as a plugin. + + + +V) Enabling the PMC on Linux + +On linux you may use oprofile from http://oprofile.sf.net, depending on the +version and the cpu you may need to apply a patch[1] to access a set of the +possibile counters from the userspace application.

It supports +several live feeds, streaming from files and time shifting on live feeds +(you can seek to positions in the past on each live feed, provided you +specify a big enough feed storage in ffserver.conf). + +This documentation covers only the streaming aspects of ffserver / +ffmpeg. All questions about parameters for ffmpeg, codec questions, +etc. are not covered here. Read @file{ffmpeg-doc.html} for more +information. +@c man end + +@chapter QuickStart + +[Contributed by Philip Gladstone, philip-ffserver at gladstonefamily dot net] + +@section What can this do? + +When properly configured and running, you can capture video and audio in real +time from a suitable capture card, and stream it out over the Internet to +either Windows Media Player or RealAudio player (with some restrictions). + +It can also stream from files, though that is currently broken. Very often, a +web server can be used to serve up the files just as well. + +It can stream prerecorded video from .ffm files, though it is somewhat tricky +to make it work correctly. + +@section What do I need? + +I use Linux on a 900MHz Duron with a cheapo Bt848 based TV capture card. I'm +using stock Linux 2.4.17 with the stock drivers. [Actually that isn't true, +I needed some special drivers for my motherboard-based sound card.] + +I understand that FreeBSD systems work just fine as well. + +@section How do I make it work? + +First, build the kit. 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). Go to Open URL and enter + +@example + http://:8090/test.asf +@end example + +You should (after a short delay) see video and hear audio. + +WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to +transfer the entire file before starting to play. +The same is true of AVI files. + +@section What happens next? + +You should edit the ffserver.conf file to suit your needs (in terms of +frame rates etc). 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 new file mode 100644 index 000000000..a3b3ff412 --- /dev/null +++ b/contrib/ffmpeg/doc/ffserver.conf @@ -0,0 +1,349 @@ +# Port on which the server is listening.

These multiplies can then be + * folded into the multiplications or divisions by the JPEG quantization + * table entries. The AA&N method leaves only 5 multiplies and 29 adds + * to be done in the DCT itself. + * The primary disadvantage of this method is that with fixed-point math, + * accuracy is lost due to imprecise representation of the scaled + * quantization values. The smaller the quantization table entry, the less + * precise the scaled value, so this implementation does worse with high- + * quality-setting files than with low-quality ones. + */ + +/** + * @file jfdctfst.c + * Independent JPEG Group's fast AAN dct. + */ + +#include +#include +#include "common.h" +#include "dsputil.h" + +#define DCTSIZE 8 +#define GLOBAL(x) x +#define RIGHT_SHIFT(x, n) ((x) >> (n)) +#define SHIFT_TEMPS + +/* + * This module is specialized to the case DCTSIZE = 8. + */ + +#if DCTSIZE != 8 + Sorry, this code only copes with 8x8 DCTs. /* deliberate syntax err */ +#endif + + +/* Scaling decisions are generally the same as in the LL&M algorithm; + * see jfdctint.c for more details.

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. Since there are no markers in the file to + * differentiate between the two variants, this demuxer uses the following + * heuristic: + * - load the 768 palette bytes from disk + * - assume that they will need to be shifted left by 2 bits to + * transform them from 6-bit values to 8-bit values + * - scan through all 768 palette bytes + * - if any bytes exceed 63, do not shift the bytes at all before + * transmitting them to the video decoder + */ + +#include "avformat.h" + +#define HUFFMAN_TABLE_SIZE (64 * 1024) +#define FRAME_PTS_INC (90000 / 14) + +typedef struct IdcinDemuxContext { + int video_stream_index; + int audio_stream_index; + int audio_chunk_size1; + int audio_chunk_size2; + + /* demux state variables */ + int current_audio_chunk; + int next_chunk_is_video; + int audio_present; + + int64_t pts; + + AVPaletteControl palctrl; +} IdcinDemuxContext; + +static int idcin_probe(AVProbeData *p) +{ + unsigned int number; + + /* + * This is what you could call a "probabilistic" file check: Id CIN + * files don't have a definite file signature.
