Jellyfin and H.265 10bit on android

[Efficient_Good_5784]

My Android phone supports H.265, and the via browser can stream normally, why does the client need to transcode? What can be done about it? I can only use the html player because I have a need for multi-group playback

Could you provide your server's logs after you play a video that transcodes on the client?

My guess is an audio track or subs that the phone app doesn't support.
