Using a webcam with new Orin system. Upon plugging in camera shows up in /dev/video
orin@orin1:~$ ls /dev/vid*
/dev/video0 /dev/video1
orin@orin1:~$ lsusb
…
Bus 001 Device 009: ID 0c45:6366 Microdia USB 2.0 Camera
…
However, within the jetson-inference containter (the Hello World AI example at https://github.com/dusty-nv/jetson-inference/blob/master/docs/aux-docker.md ) it does not show up:
root@orin1:/jetson-inference/build/aarch64/bin# video-viewer v4l2:///dev/video0

Hi @randy.goebbert ! I moved this post over to the Orin part of the forum - you’d posted it in the DGX area, and not sure it’d get the best eyes on it over there.

Hi @randy.goebbert , can you try running video-viewer with /dev/video1 instead?
same results within the container… neither /dev/video0 or /dev/video1 works:
oot@orin1:/jetson-inference/build/aarch64/bin# video-viewer v4l2:///dev/video1
[gstreamer] initialized gstreamer, version 1.16.2.0
[gstreamer] gstCamera – attempting to create device v4l2:///dev/video1
[gstreamer] gstCamera – didn’t discover any v4l2 devices
[gstreamer] gstCamera – device discovery and auto-negotiation failed
[gstreamer] gstCamera – failed to create device v4l2:///dev/video1
video-viewer: failed to create input stream
this started working when I restarted the container with the camera plugged in… not sure why, but /dev/video0 is now showing up… OK to close this
OK, glad you got it working! Yes, you must start the container after the camera gets plugged in.
