The media backend service does the work of decoding, playing and controlling the media based on requests from the Storyboard application over a Storyboard IO channel. The default Storyboard IO channel name is com.crank.media_backend. This value can be overwritten by setting the SBMEDIA_CHANNEL_NAME environment variable to a new value. The FFmpeg plugin is loaded automatically when it is present in the Storyboard plugins directory. If the gstreamer-backend is going to be used to play media, the FFmpeg plugin needs to be removed from the Storyboard plugins directory or else both backends will compete to service media requests.
