Add Bitrate, Bitdepth and Decoder information to playing track

[orenskl]

Problem to solve

Currently mopidy-iris does not present the user with the track audio stream data. I think it would be nice to add such a feature - specifically for audiophile users.

Proposed solution

Add the following information to displayed with the track data:

• Track Bitrate
• Track Bitdepth
• Track Decoder

Additional info

It really comes down to whether this data is provided by the source. While this could be 'acquired' from other sources, it wouldn't necessarily align with your specific version of the audio.

On top of this, the Mopidy Track model only supports bitrate of your requested attributes.

bitrate could be exposed and this should be relatively straightforward, at least for Mopidy-Local tracks, but other sources (Spotify HTTP API for instance) are not likely to provide this; the track will need to be loaded by Mopidy first. I would expect that the Spotify backend would determine the playback quality, so this would be the same for all Spotify tracks anyway.

Using Mopidy-tidal as a backend I get this:

{
   "id" : 1,
   "jsonrpc" : "2.0",
   "result" : {
      "__model__" : "Track",
      "album" : {
         "__model__" : "Album",
         "artists" : [
            {
               "__model__" : "Artist",
               "name" : "Amy Winehouse",
               "uri" : "tidal:artist:15796"
            }
         ],
         "name" : "Back To Black",
         "uri" : "tidal:album:2798956"
      },
      "artists" : [
         {
            "__model__" : "Artist",
            "name" : "Amy Winehouse",
            "uri" : "tidal:artist:15796"
         }
      ],
      "disc_no" : 1,
      "length" : 240000,
      "name" : "Back To Black",
      "track_no" : 5,
      "uri" : "tidal:track:15796:2798956:2798961"
   }
}

Which means that bitrate is not exposed by the backend ?

I guess this is a feature request for Mopidy and also for the relevant backend.
