    <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>
