Hello guys,
I have an issue with trying reconnect stream.
def open_cam_rtsp(uri, width, height, latency):
"""Open an RTSP URI (IP CAM)."""
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)
return cv2.VideoCapture(gst_str, cv2.CAP_GSTREAMER)
This is my format rtsp stream , i’m using HKVion camera. Everything work fine. I try to control the case when camera dont have internet connection (network not stable, camera turn off, …), so i want to call reconnect function after 5 second to make sure when the camera is activated, i can get the stream from it.
def show_camera():
while(isOpened):
cap = cv2.VideoCapture(open_cam_rtsp(url), cv2.CAP_GSTREAMER)
if cap.isOpened():
print('Connected to camera')
isOpened = True
else:
print('Unable to open camera')
isOpened = False
It run fine after hours bebore this error show , this code will stuck and dont run anymore.
