Jetson Nano with Logitech Brio

thkim0090 · January 6, 2020, 8:12am

Dear Experts,

When I connected logitech brio on jetson nano, I could stream video only 10 fps @ 4K. Is this limitation of jetsion nano or do I missed something ?

Thanks,

Hi,
Please share information of running $ v4l2-ctl --list-formats-ext
We have Logitech C930 but don’t have Brio. The information can give us some basic understanding to the camera. Also please share your release version.

Hello,

This is the output of running $ v4l2-ctl --list-formats-ext. And the release version is L4T 32.3.1.
I used GUVCViewer and set 60 fps with 4096x2160, MJPG format, streaming fps is only 8.5
Appreciate for your help.

Hi,
The optimal performance is to use tegra_multimedia_api. Please check 12_camera_v4l2_cuda sample. MJPEG format is supported.

Andrey1984 · July 6, 2020, 7:28pm

how to stream with it? in 4K? with logitech brio? so it is uses encoding to an extent when the streaming is not lagging?

 $ cd 12_camera_v4l2_cuda
  $ make
To run
Enter:

  $ ./camera_v4l2_cuda -d /dev/video0 -s 1280x720 -f YUYV -c
The -c option enables CUDA processing.

Or enter:

  $ ./camera_v4l2_cuda -d /dev/video0 -s 640x480 -f YUYV -n 30 -c

Hi,
Please set -f MJPEG if you would like to run MJPG decoding.

Hi Andrey, I am using the same camera with Jetson Nano. The below command works and thanks for that,

  $ ./camera_v4l2_cuda -d /dev/video0 -s 640x480 -f YUYV -n 30 -c

How do I use this with Opencv cv2.videocapture() ?
