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

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.
Note
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.
