Created attachment 390276 [details] Source code for repro Safari appears to never increment the currentTime property of the video element from a getUserMedia stream in iOS 13.4 Beta. A basic repro case can be viewed on an iPhone here: 8th.io/y8k4p The repro app does the following: * getUserMedia -> stream -> video * Print out videoHeight, videoWidth, and currentTime of the video We tested this with an iPhoneXR with iOS 13.4 Beta. Source code for the repro is attached.

I'll ask the obvious: this is a regression from iOS 13.3?

Yes, this is a regression observed in 13.4. We see that 13.3.1 is working as expected.

This was caused by r251566.

Is this fix expected to have been propagated to the latest iOS 13.4 Beta 2? We're still seeing the same issue after updating.
