Videocapture RTSP cause very high cpu usage

asked 2020-12-15 10:45:36 -0500

i using OpenCV 3.4.12 VideoCapture in c++ with a simple read operation from a rtsp stream. A test with a 640x360 resolution runs with very high CPU usage 40-64% on my linux box with an i7 CPU.

how can i reduce the CPU usage?

Thanks!
