<para>
|
|
<application>FFmpeg</application> 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 (<command>ffmpeg</command>) tries to figure out
|
|
all the parameters, when possible. <application>FFmpeg</application> can
|
|
also convert from any sample rate to any other, and resize video on the
|
|
fly with a high quality polyphase filter.
|
|
<application>FFmpeg</application> can use a Video4Linux compatible video
|
|
source and any Open Sound System audio source.

To properly test the installation you must have <xref linkend="rsync"/>
|
|
installed and follow the instructions for the <ulink
|
|
url="http://www.ffmpeg.org/fate.html"> FFmpeg Automated Testing
|
|
Environment</ulink> (FATE). First, about 958 MB of sample files used to
|
|
run FATE are downloaded with the command:
|
|
</para>
|
|
|
|
<screen><userinput>make fate-rsync SAMPLES=fate-suite/</userinput></screen>
|
|
|
|
<para>
|
|
The <filename class="directory">fate-suite</filename> 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 <command>make fate-rsync
|
|
...</command> 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:
|
|
</para>
|
|
|
|
<screen><userinput><command>rsync -vrltLW --delete --timeout=60 --contimeout=60 \
|
|
rsync://fate-suite.ffmpeg.org/fate-suite/ fate-suite/</command></userinput></screen>
|
|
|
|
<para>
|
|
Next, FATE is executed, with the commands (you obtain a number of tests
|
|
larger than 2500):
|
|
</para>
|
|
|
|
<screen><userinput>make fate THREADS=<replaceable>N</replaceable> SAMPLES=fate-suite/ | tee ../fate.log &&
|
|
grep ^TEST ../fate.log | wc -l</userinput></screen>
