Camera Feed Turning Black on iOS 15
On iOS 15 getUserMedia camera stream fails after viewing a screenshot (instant markup). This previously worked on iOS 14.8.
After the users exits the instant markup view, Safari give no indication of a change (‘VisibilityChange’, ‘pageshow’ are not called). At this point, (video.videoWidth>0 while video.currentTime remains 0).
Reproduction Steps:
1. Open https://webrtc.github.io/samples/src/content/getusermedia/gum/ on iOS15
2. Take a screenshot by pressing the power button and the volume up button
3. Open the screenshot preview (instant markup)
4. Either press delete, or save
5. The camera feed is now black (getUserMedia camera stream has failed)
Attached is an example video on iOS 15
Please let me know if I can provide more info, thank you.
