"A MediaStreamTrack ended due to a capture failure" if trying to show the stream in a video tag not appended to DOM

• Component: WebRTC
• Status: RESOLVED CONFIGURATION CHANGED

[Francesco Durighetto (kekkokk)]

There is a bug in safari 14 (reproducible only on mobile devices (iPhone/iPad) where a mediastream from getusermedia fires a: "A MediaStreamTrack ended due to a capture failure" if this stream is attached to a video element not present in DOM.

also, this is a bit tricky because it crashes when calling .play() on videoElement if this element is NOT attached to dom.
but if this videoElement is NOT attached. to DOM BUT it has the autoplay attribute AND you does not invoke the .play() method it seems to work.

I think the best way to describe this bug is via a simple snippet so you can try the different combinations of events and better understand the problem.
