    <para>
      <application>Transcode</application> was a fast, versatile and
      command-line based audio/video everything to everything converter
      primarily focused on producing AVI video files with MP3 audio,
      but also including a program to read all the video and audio streams
      from a DVD.

    <para>
      Although outdated and no longer maintained, it can still be used to
      extract items from a DVD using only the required and recommended
      dependencies, or to recode to AVI files.

<!-- ffmpeg5 no longer carries libavresample.
    <note>
      <para>
        The details of how the <application>FFmpeg</application> libraries
        are used has changed since this version of
        <application>Transcode</application> was released. The patch allows the
        package to be compiled, but some or all of the internal calls to
        <application>FFmpeg</application> may fail at run time (they report an error
        and processing continues, but without any output).
      </para>

      <para>
        For many packages, that would be a critical error. In this case,
        the main reason to install <application>Transcode</application> is for
        the <command>tccat</command> program, which works.  Some of the
        <command>transcode</command> options work - for the others, use
        <command>ffmpeg</command> directly on the command line.

    <note>
      <para>
        Support for most of the dependency packages requires using
