When playing Dolby Vision content on pixel 6a, the app reports that it is direct playing, however there is just a black screen for video. The audio works fine. If DV is not supported on the pixel 6a, then the app should not allow a broken direct play and force server transcoding. If I select a lower bitrate (eg1080p 10mbps) then I can get the video to show up, however it is green and purple (Jellyfin 10.8 AMD VAAPI transcoding does not support tonemapping on my vega 7 gpu).
The DV file does not play in stock video player or cx file explorer. It does play in VLC, I think that has some software/hardware decoding available. I have upgraded to JF server 10.9 and the issue persists. Looking at my network bandwidth it looks like jellyfin is sending the full file to the client and the client is receiving it and playing it just as a black screen. Once I turn down the bitrate to 1080p 40mbps, the client triggers a transcode on the server. Tone mapping works properly on 10.9 with my AMD gpu so the client just needs a manual override to lower the resolution and force a transcode because otherwise it will play a black video.
