Hi everyone, I’m trying to acces my cctv frame using rtsp but it always return ‘empty frame’. I am using HIkvision cctv camera. Here’s the code:

import cv2

rtsp_url = 'rtsp://<username>:<password>@<IP address of device>:<RTSP port>/Streaming/channels/<channel number><stream number>'

cap = cv2.VideoCapture(rtsp_url)

if not cap.isOpened():

    print("can't connect to rstp")

    exit()

while True:

    ret, frame = cap.read()

    if not ret:

        print("can't read the frame")
        break

    cv2.imshow('RTSP Streaming', frame)

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

cap.release()
cv2.destroyAllWindows()

The default distribution of VLC includes many free decoding and encoding libraries, avoiding the need for finding/calibrating proprietary plugins. The libavcodec library from the FFmpeg project provides many of VLC’s codecs, but the player mainly[15] uses its own muxers and demuxers. It also has its own protocol implementations.

may be you should try with gstreamer

Usually hik requires a username and password unless you explicitly disabled it. Did you enter a username and password in vlc the first time you connect?
