OpenCV frame capture with no output and errors (gstreamer)

[9ghtX]

I'm trying to get frames via Python OpenCV from my MIPI camera with gstreamer pipeline, but there is no any output messages like warnings, errors or cv2.imshow() frames.

Here is code that I'm trying to execute (found it in Internet):

import cv2

def receive():

    cap_receive = cv2.VideoCapture('udpsrc port=5000 caps = "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! rtph264depay ! decodebin ! videoconvert ! appsink', cv2.CAP_GSTREAMER)

    if not cap_receive.isOpened():

        print('VideoCapture not opened')

        exit(0)

    while True:

        ret,frame = cap_receive.read()

        if not ret:

            print('empty frame')

            break

        cv2.imshow('receive', frame)

        if cv2.waitKey(1)&0xFF == ord('q'

            break

    #cap_receive.release()

if __name__ == '__main__':

    receive()

    cv2.destroyAllWindows()
