Unable to select "too low" of quality of video

[Karmalakas]

when switching quality to 720p, Jellyfin could generally render the video. But switching to 480p would not load at all, and in fact made the Jellyfin player client crash. Only changing the quality back to a higher resolution, or just streaming direct would fix it

Hi, I have probably same issue... How did you manage to change back to higher quality? On Chrome player controls never appear - it just closes and I'm left back on the movie page. I can't find how to set plyback quality before starting to play. If I open the movie on Edge, it plays fine, but it's on Auto. Back on Chrome player crashes.

When I selected 480p, I got:

Code:

[av1_nvenc @ 0x563bc5cb97c0] Codec not supported
[av1_nvenc @ 0x563bc5cb97c0] Provided device doesn't support required NVENC features

[libfdk_aac @ 0x563bc5c8bc80] 2 frames left in the queue on closing
Conversion failed!

When I switch quality on Edge or mobile app to force HW encoding, I get what I would expect:
