Gonic v0.21.0 updates regarding Symfonium

Discussion
1

hey @Tolriq

gonic 0.21 is about to be released (release PR). I wanted to update you on the bits relevant for Symfonium

  • stream.view?maxBitRate=… and format=… are now honoured even without a server-side transcode profile, no more errors when the client just asks for a bitrate (#13634, #2720, #5075)
  • Admins can set per-format transcoding defaults instead of per-user profiles
  • Cached transcodes are served straight from disk with proper Range support, so seeking transcoded streams works (#13718).
  • For the first-time transcode case where there’s no cache hit yet, timeOffset and estimateContentLength are respected so the client can seek and know the size up front
  • Track-level play counts are returned, sync shouldn’t drop counts anymore (#3267)
  • Artist metadata got a big refactor: displayArtist uses ARTIST_CREDIT, artistRole is returned, per-relationship credit names and contributors are scanned, and the missing track artist on TrackChild is fixed. This is working more like LMS now
  • ISRCs, record labels, track-level year tags scanned and returned
  • OpenSubsonic error codes match the spec, /download always gives the original, scrobblingEnabled always true, averageRating is a float
  • More OS compat
  • New OS transcoding extension: Will look at this later

Given that, are there any other gonic-specific workarounds in Symfonium? Please let me know and I can update gonic before I release. So that Symfonium can have fewer (or no) gonic specific handling

Thanks!

That’s a good news. There’s no more Gonic specific code except some hacks to try to keep the track play counts that will auto recover.

As notes: I never request estimateContentLength you need to be sure to never returns the size headers if it’s not requested and unknown to avoid cache problems on clients. (Including for the cached transcode that where maybe started with an offset)

The main Gonic pain point was the transcodes. Working by default as the other will reduce users friction a lot. And even more when you’ll look as the new extension :slight_smile:

OK sounds good :+1: I’ll release then

and yes, The Content-Length header is only set when the client passes estimateContentLength=true and gonic has a known track duration

One more question, for example on this release it has two album artists, but track #4 has 4 track artists, when I click the 3 dots menu. The “Go to” artist options only list the album artists. Is this expected?

Note, for gonic, getArtistList and search3 return just album artists. Even though artists can be queried by getArtist when returned as track artists
