    <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.</para>
    <para>The developers of this package do not make releases very often, so you
    may wish to use a snapshot instead of this release.  If you do that, you must
    expect the acceptable <command>configure</command> switches, and the
    dependencies, to change.</para>

    <title>Installation of FFmpeg</title>

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

<screen><userinput>sed -i 's/-number//' Makefile &amp;&amp;
./configure --prefix=/usr --enable-shared \
            --enable-pthreads --enable-gpl \
            --enable-swscale --enable-postproc \
            --enable-libfaad --enable-libmp3lame \

            --enable-libvpx --enable-libx264 \
            --enable-libxvid &amp;&amp;
make</userinput></screen>

    <para>If you have <application>teTeX</application> or
    <application>texi2html</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, and issue the following
    commands:</para>

<screen><userinput>cd doc &amp;&amp;
for DOCNAME in faq ffmpeg-doc ffplay-doc ffprobe-doc ffserver-doc general libavfilter; do
    texi2dvi -b -p $DOCNAME.texi
    texi2dvi -b    $DOCNAME.texi

    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 150 MB of space), issue
    <command>doxygen</command>.</para>

    <para>If you wish to run the tests, issue: <command>make check</command> -
    that will take about 0.9 SBU and use another 365 MB of space.</para>

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

<screen role="root"><userinput>make install &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

<screen role="root"><userinput>install -v -m755 -d /usr/share/doc/ffmpeg-&ffmpeg-version;/api &amp;&amp;

    <para><parameter>sed -i 's/-number//' Makefile</parameter>: Recent versions
    of gnu <command>texi2html</command> error out because
    <command>-number</command> is now ambiguous (for number-footnote or
    number-sections).  Neither choice makes any difference to what is created
    here, and the same is true with older versions of
    <command>texi2html</command>, e.g. from application
    <application>teTeX</application>.</para>

    <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>--enable-gpl</parameter>: This switch enables the
    use of GPL code and permits support for postprocessing, swscale, liba54,
    xvid, x264, libfaad2 and x11grab to be selected.</para>

    <para><parameter>--enable-swscale</parameter>: This switch causes libswscale
    to be built.</para>

    <para><parameter>--enable-postprocessing</parameter>: This switch causes
    libpostproc to be built.</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. If you have not installed some of the recommended
    dependencies, do not enable those you have omitted.</para>

    <para><option>--disable-ffplay</option>: Only installs the server part.
    Use this option if <application>X</application> is not installed.</para>

    <para><option>--disable-static</option>: This switch prevents the static
    libraries from being built.</para>

    <para><command>if [ $DOCNAME = ffserver-doc ] ...</command> These three
    .texi files are rejected by <command>makeinfo</command> because of syntax
    errors.</para>
