%general-entities; ]> $LastChangedBy$ $Date$ FFmpeg FFmpeg is a solution to record, convert and stream audio and video. 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. &lfs77_checked; &gcc5_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; FFmpeg Dependencies Recommended , , , , , , , , , and Recommended for desktop use , , (with the corresponding driver package), and Optional , , (to identify and play CDs), , , or , , , (or ) for PDF and PS documentation, , , , Flite, frei0r, GSM, HEVC/H.265, LADSPA, libaacplus, libbluray, libcaca, libcelt, libdc1394, libdca, libiec61883, libilbc, libmodplug, libnut (Git checkout), librtmp, libssh, libxavs (SVN checkout), OpenAL, OpenCore AMR, OpenCV, Schroedinger, TwoLAME, vo-aaenc, vo-amrwbenc, x265 (H.265/MPEG-H HEVC), and ZVBI User Notes: 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-libfreetype \ --enable-libmp3lame \ --enable-libopus \ --enable-libtheora \ --enable-libvorbis \ --enable-libvpx \ --enable-libx264 \ --enable-x11grab \ --docdir=/usr/share/doc/ffmpeg-&ffmpeg-version; && make && gcc tools/qt-faststart.c -o tools/qt-faststart HTML documentation was built in the previous step. If you have installed and wish to build PDF and Postscript versions of the documentation, issue the following commands: sed -i '$s/$/\n\n@bye/' doc/{git-howto,nut,fate}.texi && sed -i '/machine:i386/ s/\\/@backslashchar{}/g' doc/platform.texi && 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. The fate-suite tests include comparisons with installed files, and should not be run before the package is installed. Therefore, if you desire to run them, instructions are given further below. Now, as the root user: make install && install -v -m755 tools/qt-faststart /usr/bin && install -v -m644 doc/*.txt \ /usr/share/doc/ffmpeg-&ffmpeg-version; If PDF and Postscript documentations were built, issue the following commands, as the root user, to install them: install -v -m644 doc/*.pdf \ /usr/share/doc/ffmpeg-&ffmpeg-version; && install -v -m644 doc/*.ps \ /usr/share/doc/ffmpeg-&ffmpeg-version; 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-&ffmpeg-version;/api && cp -vr doc/doxy/html/* /usr/share/doc/ffmpeg-&ffmpeg-version;/api && find /usr/share/doc/ffmpeg-&ffmpeg-version;/api -type f -exec chmod -c 0644 \{} \; && find /usr/share/doc/ffmpeg-&ffmpeg-version;/api -type d -exec chmod -c 0755 \{} \; To properly test the installation you must have installed and follow the instructions for the FFmpeg Automated Testing Environment (FATE). First, about 930 MB of sample files used to run FATE are downloaded with the command: make fate-rsync SAMPLES=fate-suite/ The fate-suite directory is created and the files are downloaded there. That command actually runs an rsync command, to obtain the sample files. You may want to compress and keep this directory for testing again, in another system, or when a new version of ffmpeg is launched. Then, you unpack the sample files in the source directory, and run, again, the make fate-rsync ... command above, to sync with the repository. Now, the download size and time are drastically reduced. Estimated values in "Package Information" do not include the download SBU. Some samples may have been removed, in the new version, so, in order to be sure local and server fate samples are identical, when you use previously saved samples, run the following command: rsync -vrltLW --delete --timeout=60 --contimeout=60 \ rsync://fate-suite.ffmpeg.org/fate-suite/ fate-suite/ Next, FATE is executed, with the commands (you obtain a number of tests larger than 2400): make fate THREADS=N SAMPLES=fate-suite/ | tee ../fate.log && grep ^TEST ../fate.log | wc -l where N is an integer, N ≤ number of threads in the system. sed -i ... configure: This command adds the ALSA library to the Flite LDFLAGS variable and enables the discovery of Flite. sed -i ... texi: Fix some .texi files for documentation builds. find ... ;: Fix permissions of documentation files and directories. --enable-libfreetype: 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-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. --enable-openssl or --enable-gnutls: Enables HTTPS protocol for network streams. 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. /etc/ffserver.conf and ~/.ffmpeg/ffserver-config ~/.ffmpeg/ffserver-config /etc/ffserver.conf You'll find a sample ffserver configuration file at doc/ffserver.conf in the source tree.
