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?
Comment 3 Christoph Bartschat 2020-02-10 16:01:47 PST
Yes, this is a regression observed in 13.4. We see that 13.3.1 is working as expected.
Comment 4 Eric Carlson 2020-02-11 10:27:25 PST
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.

No, the fix missed the cutoff for Beta 2.
