Multiple UVC USB Camera with Gstreamer

Hello,

I try to use 4 USB3 camera with Jetson NX. But I cannot get it work with the 4th camera.

The camera are connected with a USB3 hub, and here is the output of lsusb -t

4 camera are same model, here is the output of v4l2-ctl --list-formats-ext

And here is the command and output of gstreamer:

Would you have any advice to solve this problem?

Thank you.

Hi,
Looks like the 4 cameras are enumerated as superspeed. In this case, the 4 cameras share 5Gbps. So you can launch 3 cameras in 640x480p successfully and cannot launch the 4th camera?

Thank you.

Yes, I can launch 3 cameras in 640x480 with 60fps. But the 4th failed to launch.

Hi,
It looks like each camera requests for > 1.25Gbps bandwidth so that the fourth camera doesn’t get enough bandwidth. You may check UVC driver and add debug prints to show the requested bandwidth of the cameras.

I try to found out more from the UVC camera as below:

Enable all uvcvideo module traces:
echo 0xffff > /sys/module/uvcvideo/parameters/trace

And here is the output of dmesg when the camera connect to Jetson.

And when I start the 4th camera with GStreamer:

[ 1635.654562] uvcvideo: Device requested 32768 B/frame bandwidth.
[ 1635.654570] uvcvideo: Selecting alternate setting 11 (32768 B/frame bandwidth).
[ 1635.657892] usb 2-3.1.4: Not enough bandwidth for new device state.
[ 1635.658060] usb 2-3.1.4: Not enough bandwidth for altsetting 11

Seems there is not enough bandwidth for the 4th camera.

In fact, the 60fps framerate is not necessary, but I cannot find suitable USB3.0 camera with 640x480 30fps.
Are there any methods can let the cameras work with lower bandwidth?

Thank you so much.
