    344       Support for most of the dependency packages requires using options passed
    345       to the <command>configure</command> script. View the the output from
    346       <command>./configure --help</command> for complete information about
    347       enabling dependency packages. The only reason to enable a specific codec
    348       (and make <application>FFmpeg</application> link to the prerequisite
    349       shared library installed on your system) is to make
    350       <application>FFmpeg</application> compile an <emphasis>encoder</emphasis>
    351       and/or <emphasis>decoder</emphasis> for that codec. If you just want to
    352       use <application>FFmpeg</application> to watch video or listen to music
    353       (via other applications such as <application>Gstreamer</application> or
    354       <application>Xine</application>) then you will not benefit from linking
    355       <application>FFmpeg</application> to other codec libraries.
