Nvidia RTX 2080 Ti - Not Transcoding

[yoyoyopop40 0]

My NVENC/NVDEC seems to be failing upon most (if not all) conversions from 4K. Emby runs as a linuxserver docker in Ubuntu 24.04.

I receive the following transcode error:

13:30:30.255 [h264_nvenc @ 0x355990c0] Failed locking bitstream buffer: invalid param (8)
 

My NVIDIA driver is 550.67, but I've tried the latest ubuntu 535, 550, and 570 drivers too. I saw some feedback from May-24 that led me to believe 550.67 might have fixed a similar issue, so that is why I'm running it. Nvidia-smi works perfectly outside and inside docker, but the ffmpeg job only runs for about a second before exiting out.

 

Any help would be much appreciated. I have been fighting this in both Plex and Emby, so I think this is likely related more-so to nvidia, but I'm quite nascent on how this ffmpeg conversion happens so it's difficult for me to gauge too much.

Hi there, please attach the corresponding emby server log as well. Thanks.
