<title>Introduction to <application>FFmpeg</application></title>

<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.</para>

<title>Installation of <application>FFmpeg</application></title>

<para>Install <application>FFmpeg</application> by running the following 
commands:</para>

<note><para>Review the <filename>doc/optimization.txt</filename> file in the 
source tree for information about optimizing the build.</para></note>

<screen><userinput><command>sed -i -e "s/static uint64/const uint64/" \
    libavcodec/liba52/resample_mmx.c &amp;&amp;
./configure --prefix=/usr --enable-shared \
    --enable-pthreads --disable-ffplay &amp;&amp;
make</command></userinput></screen>

<para>If you have <application>TeX</application> installed, the man pages 
and documentation was built during the <command>make</command> process. Skip 
to the root user installation steps. If you do not have 
<application>TeX</application> installed, use the following command to build 
the man pages:</para>

<screen><userinput><command>make -C doc {ffmpeg,ffserver,ffplay}.1</command></userinput></screen>

<para>Now, as the root user:</para>

<screen><userinput role='root'><command>make install</command></userinput></screen>

<para>If you have <application>TeX</application> installed (which caused the 
HTML documentation to be built earlier), install the documentation by issuing 
the following commands as the root user:</para>

<screen><userinput role='root'><command>install -v -m755 -d /usr/share/doc/ffmpeg-&ffmpeg-version; &amp;&amp;
install -v -m644 doc/*.html /usr/share/doc/ffmpeg-&ffmpeg-version;</command></userinput></screen>

<title>Command explanations</title>

<para><command>sed -i -e "s/static uint64/const uint64/" 
libavcodec/liba52/resample_mmx.c</command>: This command fixes an issue 
on machines with MMX capability and use <application>GCC</application>-3.4.x 
to compile in A52 support using the <option>--enable-a52</option> parameter 
passed to the <command>configure</command> script.</para>

<para><parameter>--enable-shared</parameter>: This switch is needed to
build the <filename class="libraryfile">libavcodec</filename> and 
<filename class="libraryfile">libavformat</filename> shared 
libraries.</para>

<para><parameter>--enable-pthreads</parameter>: This switch enables the 
build to link against the Posix threads library.</para>

<para><option>--disable-ffplay</option>: Only installs the server part.
<command>ffplay</command> requires <application>X</application> for 
building. Remove this option if <application>X</application> is 
installed.</para>

<para><option>--enable-<replaceable>[codec]</replaceable></option>: Review
the available options and codecs using the 
<command>./configure --help</command> command.</para>
