Plex android app can't play h265 video files

Server Version#:1.41.5.9522-1-01
Player Version#: 10.26.0.2578 (6cc7ea1a)
Client: Samsung Tab A9+ Tablet with Qualcomm SM6375 Snapdragon 695 5G
Media: MPEG-H Part2/HEVC (H.265) (hevc) 1920x1080 / EAC3 5.1

I have a 1080P h265 video file on the server.

If I copy the 265 video file onto the tablet then it can be played in VLC.
If I try to play the local 265 video file directly in plex it will fail.

If I try to playthe 265 in plex from the server then:

  1. It fails. “An error occurred while attempting to play this video. Please check your connection”
  2. If I use external player in plex (VLC) then it plays ok
  3. If I disable Enable HEVC video Encoding (experimental) on the server, then the client will try to play the h265 file, which will fail, then the server will transcode to h264 and the client will succeed in playing back the file (albeit converted to 264).

Issue:
There is an issue with plex client not being able to playback 265 videos however VLC can play the same file. The issue is compounded by the plex client telling the server it is h265 capable, so that any transcoded video is also sent using the new 265 option.

I am not sure how to get logs out of the plex client on the tablet. I don’t see anything interesting on the server logs.

Thanks
