Hello
i am using jetson orin nx developers kit i have connected 4 cameras to available usb ports and i am running the stream using the command
ffplay -f v4l2 -input_format mjpeg -video_size 640x480 /dev/video0

i have tried every possible way but i am only able to play 2 streams rest of the cameras shows error "no space left6 on device :
i also tried using usb 3.0 hub but still lsusb -t showing all cameras on USB 2.0 and only able to play 2 streams "

What can be the possible solutions to get the stream of 4 USb cameras on jetson ORin nx arm64 64 GB

hello yasir8,

please see-also developer guide, Applications Using GStreamer with V4L2 Source Plugin.
let’s try you’re able to stream (without display) these four camera simultaneously.
for instance,
here’s fakesink element to disable preview and shows frame-rate only.
you may specify the name=sink_X to each of camera node to distinguish them.
$ gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=300 ! 'video/x-raw, width=1920, height=1080, framerate=30/1, format=YUY2' ! fpsdisplaysink text-overlay=0 name=sink_0 video-sink=fakesink sync=0 -v
