I'm trying to process with OpenCV and python a live video transmission from a WebRTC site. But I can't open the video with

cv2.videocapture (URL)

When I try to open the video whith cv2.videocapture, it returns this error: [

ERROR:0] global C:\projects\opencv-python\opencv\modules\videoio\src\cap.cpp (116) cv::VideoCapture::open VIDEOIO(CV_IMAGES): raised OpenCV exception: OpenCV(4.2.0) C:\projects\opencv-python\opencv\modules\videoio\src\cap_images.cpp:235: error: (-5:Bad argument) CAP_IMAGES: error, expected '0?[1-9][du]'

How could I open the video that is compatible with OpenCV? I appreciate it if you demonstrate the code.

Does this answer your question? [OpenCV load video from url](https://stackoverflow.com/questions/50185654/opencv-load-video-from-url) – nayab May 29 '20 at 12:46
which link are you trying to open? – nayab May 29 '20 at 12:57
The link is a webRTC page that contains images from an Ip camera – Pretto May 29 '20 at 13:17
can you post the link – nayab May 29 '20 at 13:49
This is the link: https://webrtc-streamer.herokuapp.com/webrtcstreamer.html?video=Bahia&options=rtptransport%3Dtcp%26timeout%3D60& – Pretto May 29 '20 at 13:55
I guess OpenCV has not built in support for reading webrtc stream. you must use some external libraries. – nayab May 30 '20 at 16:50
