multiple genres are either supported by format (see flac/orbis) or are
handled by convention (see mp3) - ffmpeg presents either case as a
single string, seperated by ';' (ie "Pop;Rock")
Currently the server/db does not support multiple genres and will store
the ffmpeg string as-is which is unlikely the user intention.
Introduce 'split_genre' to take the first genre token
Roku SoundBridge devices can be treated as dumb speakers; they offer a
texted based protocol, RCP, that allows the server to request the Roku
device to connect to the server's stream.mp3 and provides ability to
control volume
Roku devices appear as speakers automatically via mDNS announcements on
the server _roku-rcp._tcp
Select use of either libspotify or librespot-c as streaming backend via config
option.
librespot-c (renamed/improved spotifyc) impl has the following:
- sync interface
- seek support
- honor bitrate config, set client and thread name
- use web access token with "streaming" scope for login
- fix issue with podcast playback
Also say goodbye to file-based Spotify login.
