Issue was reproduced on an iPhone 11 on iOS 14.4.2. Not reproducible on macOS 10.15.7. 1752752 1 webkit-bug-importer 2021-04-21 08:25:57 -0700 <rdar://problem/76960230> 1752775 2 youennf 2021-04-21 09:12:41 -0700 I tried quickly on iOS 14.5 beta and was not able to reproduce. Do you see anything in the console like "A MediaStreamTrack ended due to a capture failure"? Could you try reproducing on iOS 14.5? If you can reproduce, you can send me privately a sysdiagnose? 1753302 3 Kongpheng.Nanthavongsa 2021-04-22 14:22:20 -0700 I was able to reproduce on iOS 14.5 (18E199). I wasn't able to inspect the console logs because I'm not allowed to upgrade my work laptop to iOS 14.5 yet. Sorry. In any case, I've captured a couple of sysdiagnose's and will share privately in email now. Thanks! 1754947 4 youennf 2021-04-28 00:35:12 -0700 Thanks Kongpheng, I was able to reproduce the issue. Mute/unmute is about the media element, not the capture red pill. 1754992 5 Kongpheng.Nanthavongsa 2021-04-28 05:41:02 -0700 Thanks Youenn, Can you suggest a workaround for this issue, please? I tried to find a workaround but wasn't able to mitigate. 1759843 6 Kongpheng.Nanthavongsa 2021-05-13 14:48:19 -0700 I upgraded to iOS 14.6 Beta 3 (18F5065a) and am no longer able to reproduce the issue. Thanks! 1926839 7 youennf 2023-01-20 02:06:51 -0800 I was not able to reproduce either. Given Kongpheng mentionned this is fixed in iOS14.6, marking as resolved.
