Do you use an USB webcam?

Would you show your command to run it?

Hi Hiker,

Yes. I use USB camera. it is logitech c525. The command I use to start it is: video-viewer /dev/video0

Thank you.


check first,
$ v4l2-ctl --list-formats-ext --device=/dev/video0

then, choose proper resolution,
make sure whether 1280 x 720 @30 is provided.

Additionally, you’re running it on the local machine? or remote ssh?

Hi Hiker,

I am running it on the local machine. Also1280 x 720 @30 is provided. Thank you

May I ask how to “choose proper resolution”? Thank you!

Please make sure you execute $ export DISPLAY=:0(or 1) and can see display information in executing xrandr. The error looks to be in rendering frames.

Hi DaneLLL,
Thanks for the advices!
I have tried the commands “$ export DISPLAY=:0” or “$ export DISPLAY=:1”, and execute “xlrandr” before running “video-viewer /dev/video0”. However, the error is still the same. Could you please have a look in the images for details and give me some suggestions? Thank you so much!


Please check if you can run this gstreamer command and see video preview:

gst-launch-1.0 videotestsrc is-live=1 ! nvvidconv ! ‘video/x-raw(memory:NVMM)’ ! nv3dsink

Would like to know if another EGL render works or not.

The command has run. Please find the below for the result.

Hi @sangwong416, can you try running glxinfo / glxgears to confirm the OpenGL drivers are still working?

apt-get update
apt-get install mesa-utils

Also, you could try building from source to see if that behaves any different than the container.
