HEVC/x265 Transcoding doesn't work when transcoding to browser

[dontpursueLuBu 1]

I have this weird problem with HEVC content suddenly. When a browser (tested with Edge and Firefox) watches HEVC content and it has to transcode it, the video stutters and is distorted but the sound seems to be fine. The picture updates maybe every 2 seconds and is distorted. When i watch the same content on an iPad or TV it runs fine.

Log files for the  same file, transcoding to browser (error) and the other to iPad (runs fine).

 

This is the main error i guess:

What could be the problem here?

Here's the log file for the TV playback. I had to reduce the bitrate to force transcoding.

 

By the way: Emby runs in a docker container on Unraid.

Believe is fixed in next beta as there are several topics in the testing area in reference to that specific error.

Do you have a CUVID decoder if you change HWA to Advanced?

Making it the primary decoder should correct the issue now until another fix goes out in the next release.

Works like a charm, thanks!
