+BNB_SUBSONIC_CUSTOM_CLIENTS | undefined | Comma delimeted mime types for custom subsonic clients when streaming. Must specify by the source mime type and the transcoded mime type. For example; <p>If you want to simply re-encode some flacs, then you could specify just "audio/flac".  <p>However; if your subsonic server will transcode the track then you need to specify the resulting mime type, ie. "audio/flac>audio/mp3" <p>If you want to specify many something like; "audio/flac>audio/mp3,audio/ogg" would use client = 'bonob+audio/flac' for flacs, and 'bonob+audio/ogg' for oggs.  <p>!!!
