Jetson TX2 and FFmpeg - Can't initialize nvrm channel

[DaneLLL]

Hi,

@skala.antonin

Seems that user need to be in video group to be able to use decoder, could you confirm that?

Yes, it is correct. Permission issue may happen if the user is not in video group. Please refer to this topic:

nvidia-docker seems unable to use GPU as non-root user

When you are running on a system which does not allow non-root, run the “groups” command. Is that user a member of “video”? If not, try adding the user to “video”: “sudo usermod -a -G video ”. Note the “-a” is for append and is important…append adds to a group, and without this, the entire set of groups would instead be replaced by only “video”.
