Jetson AGX Orin Unable to read data from USB video capture card!

  • Hardware :Jetson AGX Orin & USB video capture card & four camera.
  • Jetpack Version: 5.0.2
  • Issue : Orin Unable to open the video feed from all four cameras simultaneously. No matter whether I use one or two usb video capture cards, the situation remains the same. With ffplay, it can only open a maximum of three cameras. If I attempt to open the fourth one, all outputs freeze. As soon as I close one of the four camera feeds, the other three can display the video normally.The issue does not occur on an x86 computer.
    What could be the situation causing this issue? Looking forward to your response.
    system status:

Please check if the device supports v4l2 interface. If capturing frame data through v4l2 is supported, please try the steps in Jetson AGX Orin FAQ

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

thank you !

The above problem still exists. The previous problem disappeared because I plugged a USB drive into Orin’s USB. As long as I plug in the USB drive, I can display data from four cameras. Only when I unplug the USB drive, one of the output images will go black.

We suggest upgrade to latest Jetpack 5.1.2 and try again. Certain issues are fixed in later releases.

And please try to connect to a USB hub with external power supply. Some devices require more power while running.
