Gstreamer lag increases with frame rate recording from Raspberry Pi camera (nvarguscamerasrc and nvivafilter)

It is common AFAIK that Argus takes some CPU time (@120 fps, may take one core 100%; maybe more on Nano).

Did you boost clocks with jetson_clocks script ?

Also try boosting clocks for VI/VIC/NVENC such as here for VIC:

Using VPI in GStreamer

Probably you’re not familiar with sysfs. It is an interface between kernel space where drivers are and userspace where we are when using the kernel. It is organized as directories/pseudo-files (thus size 0). Each driver can expose some parameters, features, as pseudo-files. You can read these from shell with cat, it will give you the current value of the parameter. So : # This will show what properties VIC driver exposes: ls /sys/kernel/debug/vic # This would read current average activity of …
