I cannot reproduce it in Fx52.0, 45.7.0esr and 54.0a1 (2017-03-04) (32-bit) on Win10.
Component: Audio/Video: Playback → Video/Audio Controls

I cannot make the video display as a live video, always get total time after refresh. 

Changing component back to audo/video playback as video controls' display varies according to what (meta)data it got, I guess total time should not be "unknown" to video controls in this case.

This seems to be an old regression:

Given that this regression is so old, let's just treat it as a regular bug.

I'm guessing it is an issue with the webm file itself but the file is no longer available.
Can you provide another WebM file that reproduces the bug?

It seems that I no longer reproduce this issue with other WebM files. I will mark this issue as WORKSFORME (feel free to change this if you encounter this issue).
