I try, it work gst-launch-1.0 rtspsrc location=rtsp://admin:xxxx@10.130.128.xx ! decodebin ! nvvideoconvert ! nvdsosd ! nvegltransform ! nveglglessink why in python, not work gst_str = "rtspsrc location=rtsp://admin:xxxx@10.130.128.xx ! decodebin ! nvvideoconvert ! nvdsosd ! nvegltransform ! nveglglessink" cap = cv2.VideoCapture(gst_str, cv2.CAP_GSTREAMER) while True: _, frame = cap.read() cv2.imshow('RTSP stream', frame) if cv2.waitKey(1) == 27: break error cv2.imshow('RTSP stream', frame) cv2.error: /build/opencv-XDqSFW/opencv-3.2.0+dfsg/modules/highgui/src/window.cpp:304: error: (-215) size.width>0 && size.height>0 in function imshow

Hi, You may also try this: I got the RTSP video stream on the jetson nano and ran it for about 50 frames before returning false - #7 by DaneLLL

I try to follow the example same error cv2.error: /build/opencv-XDqSFW/opencv-3.2.0+dfsg/modules/highgui/src/window.cpp:304: error: (-215) size.width>0 && size.height>0 in function imshow try open rtsp “rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov” ,it work T-T

Hi, So this does not work: rtspsrc location=rtsp://admin:xxxx@10.130.128.xx ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw,format=BGR ! appsink Please try gst-launch-1.0 command to make sure URI is valid: gst-launch-1.0 rtspsrc location=rtsp://admin:xxxx@10.130.128.xx ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw,format=BGR ! fakesink

Hi, DaneLLL I don’t mean that. I’m using the sorce “rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov” from the example, but same error I try run : gst-launch-1.0 rtspsrc location=rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov ! rtph264depay ! h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw,format=BGR ! fakesink Result: No response at… Setting pipeline to PAUSED ...

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

Hi,
The last plugin has to be appsink. It does not work with nveglglessink. Please refer to this sample:
Doesn't work nvv4l2decoder for decoding RTSP in gstreamer + opencv - #3 by DaneLLL
