Argus timing off when 2 cameras are present

[kjasper]

Hi,

I am using argus to capture from 2 different sensors simultaneously. The timings of acquireFrame are all over the place, sometimes off by 8ms.

When I enable one sensor it works perfectly.

Also the timings are thrown off when using a single camera when the system is under heavy load. Is there a way to prioritize the nvargus-daemon process?

Try boost the system to try.

sudo nvpmodel -m 0
sudo jetson_clocks
sudo su

I would like to try the v4l2 api to get around this issue but the camera_unit_sample doesn’t work for me, it hangs and dmesg prints “stuck waiting”

[kjasper]

checking in on this

[kjasper]

Does camera_unit_sample work for you?

[ShaneCCC]

Does the Multi Session of argus_camera working?

[kjasper]

I figured out it runs, but it will hang and segfault if gstreamer has been run before camera_unit_sample
