It is a very fast video and audio converter and it can also acquire from a live audio/video source. Designed to be intuitive, the command-line interface (ffmpeg) tries to figure out all the parameters, when possible. FFmpeg can also convert from any sample rate to any other, and resize video on the fly with a high quality polyphase filter. FFmpeg can use a Video4Linux compatible video source and any Open Sound System audio source. &lfs74_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &ffmpeg-md5sum; Download size: &ffmpeg-size; Estimated disk space required: &ffmpeg-buildsize; Estimated build time: &ffmpeg-time; Additional Downloads Required patch (in case you build with freetype support): FFmpeg Dependencies Recommended , , , , , , , , and Recommended for desktop use , , , and (with the corresponding driver package) Optional , , , , , , , , frei0r, , LADSPA, libssh, ZVBI, libaacplus, libbluray, libcaca, libcelt, libcdio, libdc1394, Flite, GSM, libiec61883, libilbc, libmodplug, libnut (Git checkout), OpenCore AMR, OpenCV, librtmp, Schroedinger, TwoLAME, Video4Linux, vo-aaenc, vo-amrwbenc, libxavs (SVN checkout), OpenAL, and texi2html (to build HTML documentation) User Notes: Installation of FFmpeg In case you are building with freetype support (see "Command Explanations", below), apply this patch: patch -Np1 -i ../ffmpeg-&ffmpeg-version;-freetype-1.patch Install FFmpeg by running the following commands: sed -i 's/-lflite"/-lflite -lasound"/' configure && ./configure --prefix=/usr \ --enable-gpl \ --enable-version3 \ --enable-nonfree \ --disable-static \ --enable-shared \ --disable-debug \ --enable-libass \ --enable-libfdk-aac \ --enable-libmp3lame \ --enable-libopus \ --enable-libtheora \ --enable-libvorbis \ --enable-libvpx \ --enable-libx264 \ --enable-x11grab && make && gcc tools/qt-faststart.c -o tools/qt-faststart && unset LIBRARY_PATH HTML documentation was built in the previous step if texi2html is installed. If the HTML was built (check for any .html files in the doc directory) and you have installed and wish to build PDF and Postscript versions of the documentation, issue the following commands: pushd doc && for DOCNAME in `basename -s .html *.html` do texi2pdf -b $DOCNAME.texi && texi2dvi -b $DOCNAME.texi && dvips -o $DOCNAME.ps \ $DOCNAME.dvi done && popd && unset DOCNAME If you have installed and wish to create the API documentation (takes about 350 MB of space), issue the command doxygen doc/Doxyfile. To properly test the installation you must have installed and follow the instructions for the FFmpeg Automated Testing Environment (FATE). First, about 736 MB of data files used to run FATE are downloaded. Next, FATE is executed. Estimated values in "Package Information" do not include the download SBU. Now, as the root user: make install && install -v -m755 tools/qt-faststart /usr/bin && install -v -m755 -d /usr/share/doc/ffmpeg && install -v -m644 doc/*.txt \ /usr/share/doc/ffmpeg If HTML documentation was built, issue the following command to install it: install -v -m644 doc/*.html \ /usr/share/doc/ffmpeg If you used doxygen to create the API documentation, install it (another 300 MB of space) by issuing the following commands as the root user: install -v -m755 -d /usr/share/doc/ffmpeg/api && install -v -m644 doc/doxy/html/* \ /usr/share/doc/ffmpeg/api Command Explanations sed -i ...: This command adds the ALSA library to the Flite LDFLAGS variable and enables the discovery of Flite. : Enables Freetype support. --enable-gpl: Enables the use of GPL code and permits support for postprocessing, swscale and many other features. --enable-version3: Enables the use of (L)GPL version 3 code. --enable-nonfree: Enables the use of nonfree code. Note that the resulting libraries and binaries will be unredistributable. --enable-shared: Enables building shared libraries, otherwise only static libraries are built and installed. --disable-debug: Disables building debugging symbols into the programs and libraries. --enable-libass: Enables ASS/SSA subtitle format rendering via libass. --enable-libfdk-aac: Enables currently the highest-quality AAC audio encoding via libfdk-aac. --enable-libmp3lame: Enables MP3 audio encoding via libmp3lame. --enable-libopus: Enables Opus encoding for low latency streaming via libopus. --enable-libvorbis --enable-libtheora: Enables Theora video encoding via libvorbis and libtheora. --enable-libvorbis --enable-libvpx: Enables WebM encoding via libvorbis and libvpx. --enable-libx264: Enables high-quality H.264/MPEG-4 AVC encoding via libx264. --enable-x11grab: Enables X11 grabbing. gcc tools/qt-faststart.c -o tools/qt-faststart: This builds the qt-faststart program which can modify QuickTime formatted movies (.mov or .mp4) so that the header information is located at the beginning of the file instead of the end. This allows the movie file to begin playing before the entire file has been downloaded. Support for most of the dependency packages requires using options passed to the configure script. View the output from ./configure --help for complete information about enabling dependency packages.
