Hi guys
I am having problem with reading frames from rtsp link. I can open stream by doing
ffplay -rtsp_transport tcp -i "rtsp://admin:Admin123456*@@192.168.8.191:554/cam/realmonitor?channel=1&subtype=0"
or open it with VLC. But when using cv2 to open it I get timeout problem.
[ WARN:0@30.045] global cap_ffmpeg_impl.hpp:453 _opencv_ffmpeg_interrupt_callback Stream timeout triggered after 30034.740031 ms
[ WARN:0@60.095] global cap_ffmpeg_impl.hpp:453 _opencv_ffmpeg_interrupt_callback Stream timeout triggered after 30045.549792 ms
Error: Cannot grab frame from RTSP stream.
Any explanation. I installed the environment and ran the source code on wsl2’s Ubuntu 24.04 distro
import cv2
rtsp_url = "rtsp://admin:Admin123456*@@192.168.8.191:554/cam/realmonitor?channel=1&subtype=0"
cap = cv2.VideoCapture(rtsp_url, cv2.CAP_FFMPEG)
if not cap.isOpened():
print("Error: Cannot open the RTSP stream.")
exit()
while True:
ret, frame = cap.read()
if not ret:
print("Error: Cannot grab frame from RTSP stream.")
break
cv2.imshow("RTSP Stream", frame)
if cv2.waitKey(30) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
