      Jellyfin MPV Shim is a client for the Jellyfin media server which plays media in the
      MPV media player. The application runs in the background and opens MPV only
      when media is cast to the player. The player supports most file formats, allowing you
      to prevent needless transcoding of your media files on the server. The player also has
      advanced features, such as bulk subtitle updates and launching commands on events.
