    <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.
