Poor transcoding performance in proxmox - croxis - 2023-06-19
Hello! I have jellyfin running in an arch linux lxc container in proxmox. I've been successfully running transcoding on an old nvidia with nvenc. For reasons* I had to switch it out with an amd 560 with vaapi. 10bit 4k transcoding to 1080 is now about 14 fps, resulting in jumpy playback. Is the card that poor performing? Or are there other things I can try to diagnose where the problem is?
*FFmpeg on arch now needs nvenc 12, but the legacy drivers for my 660 only suppot nvec 11
RE: Poor transcoding performance in proxmox - skribe - 2023-06-19
The first step here would probably be to share an ffmpeg log for one of the poorly performing streams so that we can look to make sure that the hardware acceleration is even working correctly. But also, yes, AMD cards are significantly worse, as a category, at HWA transcoding. So it MIGHT just be the card. But go ahead and share your ffmpeg log and we can look at it to get a better picture.

You have to setup hardware acceleration by checking our docs. Jellyfin FFmpeg is required for the best performance.

RE: Poor transcoding performance in proxmox - croxis - 2023-06-19
Solved
The instruction I failed to follow was switching jellyfin's playback's ffmpeg's path to /usr/lib/jellyfin-ffmpeg/ffmpeg For some reason it was set to the vanilla ffmpeg.
