V4L2 + GPU

Dear all,

I am using an USB3 webcam connected to the Jetson Nano, using V4L2 through OpenCV.
Doing some video processing, the frame rate is too low for what I am doing.

So, I would like to know if it is possible to add the GPU to the V4L2 to speed up the processes.
If yes, could you please tell me how to do that ?

Thank you for your help and support.

best regards,
