High CPU usage of nvargus-daemon

Hi,

We are seeing the following CPU usage for nvargus-daemon when capturing with nvarguscamerasrc on Xavier NX / Jetpack 4.6 / 1280x720@60 fps:

2 cameras: 94%
4 cameras: 170%
6 cameras: 256%

Q1) This CPU usage seems high and increases considerably with the number of cameras. Is this the expected CPU load and behavior for nvargus-daemon?
Q2) How can we reduce the CPU usage of nvargus-daemon?

Thanks

  1. Yes
  2. Reduce the frame rate.

I have a similar query.
Im running 5x 1920x1080p at 30FPS 5 cameras causes nvargus-daemon to be near 100% CPU on the xavier.

And then each gstreamer command consumes about 14%cpu leading two having almost 2 cores completely consumed just to stream cameras.

Its not particularly advantage to reduce the frame rate much lower.
