I'm trying to process with OpenCV and python a live video transmission from a WebRTC site: https://webrtc-streamer.herokuapp.com... But I can't open the video with cv2.videocapture (URL).

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

you probably need to show us, how you stream it, and your attempt at the side, receiving it

it's likely, you're doomed, since neither ffmpeg nor gstreamer can handle webrtc connections

@Pretto. I can see live on website. Can you post code, so I can do on my newest raspberry pi 4B with 8GB ram.

@supra56

I can see live on website

means: using a browser, not VideoCapture, right ?

That right. But I know that he wanted to do in OpenCV.. Unfortunately, I'm not doing on my machine.

@berak. Never mind. I do it myself. I will use both picamera and usb webcam.
