    <title>Introduction to libmpeg2</title>

    <para>The <application>libmpeg2</application> package contains a library
    for decoding MPEG-2 and MPEG-1 video streams. The library is able to decode
    all MPEG streams that conform to certain restrictions: <quote>constrained
    parameters</quote> for MPEG-1, and <quote>main profile</quote> for MPEG-2.
    This is useful for programs and applications needing to decode MPEG-2 and
    MPEG-1 video streams.</para>
