Hi team,

We’re working with a custom board based on the Jetson Orin NX module running JetPack 6.0, which includes Jetson Linux 36.3 with Kernel 5.15 and an Ubuntu 22.04 root file system.

We can stream from our cameras /dev/video0 and /dev/video1 using GStreamer pipelines or VLC, but we get the error “video4linux video1: Error opening VI capture channel node /dev/capture-vi-channel0 with err: -1” when we try to access our camera(/dev/video0) through Google Meet or Zoom.
Could you please help us debug this? Thank you in advance!

Hi,
If the camera source supports v4l2 interface, please try

Jetson AGX Orin FAQ
Q: I have a USB camera. How can I launch it on AGX Orin?

And see if it can be launched in gst-launch-1.0 command.

Hi,
We can stream using the gst-launch-1.0 command, vlc, and other streaming apps. But when we are trying to access the camera using google meet or zoom we are facing the error.

Hi,
Does Google Meet or Zoom use v4l2 interface? Would like to confirm this.

Hi,
Our camera device is listed in Google Meet and Zoom, but when we enable video from it, we get an error.

Hi,
Please remove the libs for a try:

Q: Cannot run Cheese app to launch a USB camera

/usr/lib/aarch64-linux-gnu/tegra/libv4l2_nvargus.so

See if it helps.

Hi,
It is not working. Still, we cannot get the stream in Google Meet and Zoom.

Hi,
This would need other users to share experience. For Cheese app, we can launch USB cameras after removing the libs:
Open cheese failed in JetPack 6.0 - #6 by DaneLLL

/usr/lib/aarch64-linux-gnu/tegra/libv4l2_nvargus.so

This may be due to different implementation in application, so the same approach does not work. Would see if other users have experience and can share suggestion.
