I want to know, only efficient way for decoding RTSP stream via HW decoder is gstreamer? If yes, we need write each of component like pre-processing and inference and post-processing in gsteamer programming?
There is not way to access the frames in python efficient way? not opencv this is cpu based.
A quick solution is to use gstreamer. You may use Live555 + jetson_multimedia_api but it requires effort of integration.
