The driver version Linux X64 (AMD64/EM64T) Display Driver Version: 550.54.14 is not letting me use nvenc on my Quadro T400 4GB
This error is appearing in ffmpeg
[2024-02-26 20:08:53.77777] [ERROR] [Decoder] [h264_nvenc @ 0x563ce7a19300] Failed locking bitstream buffer: invalid param (8): [2024-02-26 20:08:53.77792] [ERROR] [Decoder] Error submitting video frame to the encoder
After trying to see what is happening, I found that the driver had a problem, I replaced it with version 550.40.07 and nvenc started working again.
Same here on GTX 1650, roll back to 550.40.07 fixes problem

Hi,
I have the same problem with OBS on Linux (flatpak official version) I have a 1650 too and I get the same error:
[h264_nvenc @ 0x55ae07ff43c0] Failed locking bitstream buffer: invalid param (8):
warning: [NVIDIA NVENC H.264 (FFmpeg) encoder: 'advanced_video_recording'] ffmpeg_video_encode: Error encoding: Argumento inválido
Could it be related to this problem?https://www.reddit.com/r/obs/comments/1ay3qoa/how_to_fix_nvenc_error_get_encoded_packet/
The error it presents is the same as what was happening on the GTX 16… where the nvenc encode does not work and presents an error, in my case I am trying to reproduce an ffmpeg file to rtmp and hls and the encode does not work
ffmpeg out

Rolling back fixed this for me as well.
Could you explain how to perform the rollback please? Using apt-cache policy nvidia-driver-550 only lists two versions 550.54.14-0ubuntu1 (installed) and 550.67-0ubuntu1.22.04.2 (can’t be installed). I’m on Ubuntu 22.04 and having this same bug. I tried installing using the .run file in recovery mode. It failed on creating the kernel module.
