Unable to utilize all the virtual streams


As per the documentation Jetson NX can access upto 30 streams of video with Deepstream object detection. I was able to go only upto 19 streams, after which Jetson hangs and gives a memory error.

I tried enabling all the CPU’s, memory swap … is there something I’m missing ?
