      Dragon Media Backend is a Qt C++ library intended for desktop music players.
      It can play any audio format that FFmpeg decodes and outputs it through a
      plugin system of audio sinks with support for PipeWire, PulseAudio, and SDL.
    </p>
    <p>
      It also calculates FFTs for audio visualizations, can play music over KDE's
      KIO system, plays audio CDs and provides basic audio CD track information,
      and supports ICY metadata for radio streams.
