VP9 on Android Exoplayer transcoding

[tbjf]

As far as I can see, the supported formats are hardcoded in.

See line 206: https://github.com/jellyfin/jellyfin-and...Builder.kt

Could "vp9" just be added to that list, as I understand that it is (perhaps with rare exceptions) going to be completely playable? This would stop transcoding unnecessarily, and brings it into line with the Android TV app and the Web Player. It's a very common and pretty good codec.

(I haven't quite been able to work out where the TV app does it, maybe from here?: https://github.com/jellyfin/jellyfin-and...tReport.kt )
