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.
