PowerServiceHWVic::cleanResources - what does this usually mean? OpenCV + Gstreamer

Hi!

This is my first post and I’m trying to weed out the gotchas for the nano. I’m using gstreamer and the nano to do some simple face detection and I notice that my scripts can’t gracefully exit. By this I mean that gstreamer can’t free up resources completely, and I noticed only specifically when I run heavy computations like:

eyes = classifier.detectMultiScale(gray_frame, 1.3, 5) # detect eyes

Could someone explain to me what is going on or the workarounds for this? Force quitting and hitting ctr-c to end my script once or twice is fine but gets to anyone if you have to run it repeatedly when prototyping

Hi,
Please execute ‘sudo jetson_clocks’ to run in max performance. And run ‘sudo tegrastats’ to get system loading. Probably the system loading is too heavy.

The print is a service in nvarguscamerasrc that controls DFS(dynamic frequency scaling) of VIC engine. You nay set property ‘maxperf=1’ to always rub the engine in max clock.
