The following error shows up whenever getUserMedia is called: 2021-09-27 15:11:28.279138+0100 HelloCordova[1108:514247] Could not create a 'com.apple.tccd' sandbox extension Could not create a 'com.apple.tccd' sandbox extension 2021-09-27 15:11:28.279245+0100 HelloCordova[1108:514247] [WebRTC] Unable to create com.apple.tccd sandbox extension The correct info.plist entries are added for camera/mic. The media device permission dialog shows and is allowed (still shows if permissions were previously granted, and show as granted in the OS private settings). A MediaStream is a live audio track and a video track is still returned, but setting it on a video element doesn't do anything, neither can the stream be sent over a PeerConnection. 1797448 1 youennf 2021-09-27 07:37:30 -0700 Thanks for the report Darius, this might be bug 230479. To workaround the issue until bug 230479 ships, you might need to update your custom scheme URL to include a domain name instead of having it empty. If that is not bug 230479, could you send me a sysdiagnose privately (youenn@apple.com)? 1797449 2 darius.chris.k 2021-09-27 07:41:40 -0700 Thanks for the reply Youenn, concur that it is most likely the bug you mentioned as this is in a Cordova app, which uses some cdv:// custom url I suspect. 1797496 3 youennf 2021-09-27 09:05:03 -0700 *** This bug has been marked as a duplicate of bug 230479 ***
