I have managed to reproduce this issue on the latest Firefox (50.1.0) release and latest Nightly (53.0a1) build on Mac Os 10.11 and also on Windows 7. 

I have tested on a Firefox en-us build and the video dimensions are displayed as "NaNpx x NaNpx". For testing this I have used the provided URL in comment 0 and also with another video: https://goo.gl/WVOzft.
Here is a screenshot with the issue: https://goo.gl/uvMynM.

The dimensions were correctly displayed on Firefox 42.0a1. I have performed a regression and here are the results:
