To reproduce: * Using iOS Safari, go to https://webrtc.github.io/samples/src/content/peerconnection/pc1/ * On the console, enter: var video = $('#remoteVideo'); video.onpause = () => { console.log('paused; resuming play'); video.play(); } * Click Start button. If prompted for access for camera and microphone, then grant access * Click Call button to start the one-to-one video call * Using another phone, call the iPhone iOS Safari is running on * From iPhone iOS Safari is running on, reject the call * Notice that only one of the videos resumes. The other does not. We have a potential workaround for this issue. Initial testing looks OK. That said, will need to test more thoroughly. The heuristic: * When the pause event is dispatched after a phone call ends, check "paused" state of all video elements in application * If other videos are paused as well, then they were likely paused because a phone call just ended * Call play() on all video elements to ensure they're all resumed 1769268 1 webkit-bug-importer 2021-06-13 09:25:14 -0700 <rdar://problem/79261528>
