Hello NVidia forums!
I’ve been having trouble for a few days with my nvidia driver crashing at seemingly random when used to do nvidia-ffmpeg-transcoding ( including scale_npp).
the development env is: CentOS8.0/ CUDA 11.6/GPG driver 510.47.03/ffmpeg4.2.1
The interesting bit is below, I really need NVdia expert’s help to find out the root cause for this issue, I’m looking forward to your feedback, if any more information required ,pls be feel free to let me know:)
