If remote party doesn't support urn:3gpp:video-orientation, then Safari doesn't send video if camera was rotated to left. What steps will reproduce the problem? Here is tweaked WebRTC PeerConnection sample (https://p3.flashphoner.com:4443/samples/src/content/peerconnection/pc1/), in this example SDP 'extmap' removed before applying with setLocalDescription. 1) Press Start 2) Press Call 3) Try to rotate phone to left, video is freeze, try to rotate phone to right, video is going back. What is the expected result? The video should not freeze during any rotation. What do you see instead? Video freezes on iOS safari when camera orientation changed to left. What version of the product are you using? On what operating system? iPhone: iPhone 5S with iOS 12.2 with Safari.
