    <title>Introduction to FFmpeg</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. The developers of this package do not create or distribute package
    tarballs any longer. BLFS created the tarball for this package by checking
    out from upstream SVN the <application>FFmpeg</application> code dated
    June 6, 2007.</para>

    <title>Installation of FFmpeg</title>

      <para>Review the <filename>doc/optimization.txt</filename> file in the
      source tree for information about optimizing the build. Additionally,
      you may want to build the postprocessing library as other packages such
      as <application>MPlayer</application> and
      <application>Transcode</application> can utilize it (see the
      <quote>Command Explanations</quote> section for additional
      information).</para>

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

<screen><userinput>./configure --prefix=/usr \
            --enable-shared \
            --enable-pthreads \
            --disable-ffplay &amp;&amp;
sed -i 's|/man|/share/man|' config.mak &amp;&amp;
make &amp;&amp;
texi2html --version >/dev/null 2>&amp;1 || make doc/ff{mpeg,play,server}.1</userinput></screen>

    <para>If you have <application>teTeX</application> installed, the HTML
    documentation was built during the <command>make</command> process. If you
    wish to create additional formats of the documentation, you must have
    <application>teTeX</application> installed, then issue following
    commands:</para>

<screen><userinput>cd doc &amp;&amp;
for DOCNAME in faq ffmpeg-doc hooks ffserver-doc ffplay-doc; do
    texi2dvi -b -p $DOCNAME.texi
    texi2dvi -b    $DOCNAME.texi
    dvips -o $DOCNAME.ps $DOCNAME.dvi
    if [ $DOCNAME = ffserver-doc ] || [ $DOCNAME = ffplay-doc ]; then \
        continue
    fi
    makeinfo --plaintext --force -o $DOCNAME.txt $DOCNAME.texi
done &amp;&amp;
cd .. &amp;&amp;
unset DOCNAME</userinput></screen>

    <para>If you have <xref linkend="doxygen"/> installed and wish to create
    the API documentation (takes about 100 MB of space), issue
    <command>doxygen</command>.</para>

    <para>This package does not come with a test suite that works.</para>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>make install &amp;&amp;
install -v -m755 -d        /usr/share/doc/ffmpeg-&ffmpeg-version; &amp;&amp;
install -v -m644 doc/*.txt /usr/share/doc/ffmpeg-&ffmpeg-version; &amp;&amp;
texi2html --version >/dev/null 2>&amp;1 || make install-man</userinput></screen>

    <para>If you created additional formats of the documentation,
    install it by issuing the following commands as the
    <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>install -v -m644 doc/*.{html,dvi,pdf,ps} \
    /usr/share/doc/ffmpeg-&ffmpeg-version;</userinput></screen>

    <para>If you created the API documentation, install it by issuing the
    following commands as the
    <systemitem class="username">root</systemitem> user:</para>
 
<screen role="root"><userinput>install -v -m755 -d /usr/share/doc/ffmpeg-&ffmpeg-version;/api &amp;&amp;

    <para><parameter>--enable-shared</parameter>: This switch is needed to
    build the shared libraries, otherwise only static libraries are built
    and installed.</para>

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

    <para><parameter>--disable-ffplay</parameter>: 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>&lt;codec&gt;</replaceable></option>: Review
    the available options and codecs using the
    <command>./configure --help</command> command. You must explicitly enable
    each optional codec. Note that if you wish to build support for
    postprocessing, liba52, xvid, x264, libfaad2, x11grab or swscaler, you
    must pass <option>--enable-gpl</option> to the
    <command>configure</command> script.</para>

    <para><command>texi2html --version ...</command>: These commands are used
    to check the presence of the <application>teTeX</application> package, and
    builds/installs the man pages if it is not found.</para>
