I admit that I'm not an expert. Try to make my living of writing apps in Qt.
However, when I point WebView to opensource webRTC url:
https://webrtc.github.io/samples/src/content/getusermedia/gum/
the problem is the same: Can't access camera and microphone.
Please explain me, how open source webRTC should be different in that case ?
There is open source webRTC in Qt and I'm sure it works in QWebEngineView.
But since on mobile platform only available component is a WebView in which I
can't access camera and microphone what is the difference between opensource
webRTC and commercial JS library?
