FFmpeg-2.5.4
      
      
        
          Introduction to 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.
        
        
          This package is known to build and work properly using an LFS-7.7
          platform.

          Installation of FFmpeg
        
        
          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-libtheora  \
            --enable-libvorbis  \
            --enable-libvpx     \
            --enable-libx264    \
            --enable-x11grab    \
            --docdir=/usr/share/doc/ffmpeg-2.5.4 &&
make &&
gcc tools/qt-faststart.c -o tools/qt-faststart
        
          HTML documentation was built in the previous step. If you have
          texlive-20140525 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 Doxygen-1.8.9.1 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-2.5.4
        
          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-2.5.4 &&
install -v -m644 doc/*.ps  \
                 /usr/share/doc/ffmpeg-2.5.4
        
          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-2.5.4/api                       &&
cp -vr doc/doxy/html/* /usr/share/doc/ffmpeg-2.5.4/api                    &&
find /usr/share/doc/ffmpeg-2.5.4/api -type f -exec chmod -c 0644 "{}" ";" &&
find /usr/share/doc/ffmpeg-2.5.4/api -type d -exec chmod -c 0755 "{}" ";"
        
          To properly test the installation you must have rsync-3.1.1
          installed and follow the instructions for the FFmpeg Automated Testing
          Environment (FATE). First, about 882 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 previous 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 2300):
        
        
make fate SAMPLES=fate-suite/ | tee ../fate.log &&
grep ^TEST ../fate.log | wc -l

          before the entire file has been downloaded.
