<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>Command explanations</title>

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

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

<para><command>make -C doc {ffmpeg,ffserver,ffplay}.1</command>: This builds 
the man pages which are installed by <command>make install</command>.</para>

<note><para>Linking the <application>liba52</application> library using the 
<option>--enable-a52</option> parameter to <command>configure</command> is 
known to break the build.</para></note>
