Conflict between video/x-raw and rtsp source

[DaneLLL]

Hi,
We have clarified that OpenCV only accepts CPU buffers(video/x-raw) in multiple posts:

Is busy CPU usage when jetson nano hardware decoding is doing task?

Hi, No, tegra_multimedia_api is not supported in python. The CPU usage is explained. If you have to use appink in OpenCV, please realize it.

Pipeline multi-stream hardware decoder RTSP with jetson nano

Hi guys, I want to do pipeline multi-stream decoder on jetson nano using H264 hardware decoder. when I run directly this function: def stream_rtsp(uri, width, height, latency): gst_str = ('rtspsrc location={} latency={} ! ’ 'rtph264depay ! h264parse ! omxh264dec ! ’ 'nvvidconv ! ’ 'video/x-raw, width=(int){}, height=(int){}, ’ 'format=(string)BGRx ! videoconvert ! ’ ‘appsink’).format(uri, latency, width, height) then I check to use NVDEC ro not with sudo tegrastats, I see NVDEC is ac…

video/x-raw(memory:NVMM) element of gstreamer don't work on jetson nano

Opencv videoCapture only read frames in CPU memory. For your case you would try nvivafilter. (Here is an example for fisheye undistort, you would adapt for your case)
