sakal will disable the test for now.

sakal: Can you file a bug in a suitable Mozilla bug tracker as well?

Marking as duplicate since I think this is likely related to the failures of this test a month ago.

The following revision refers to this bug:

The test was disabled again, but I don't see any indications (pother than the test failing) that this is a dup - did someone check the symptoms match?  (Call established, but no video, and the W->CSS/CCS->W issues?

I'll check what changed in Firefox in that small window

I can run this test locally and it works fine.

So when I test calls between Chrome 52 and Firefox 51 on appr.tc I see the following:
- if Chrome creates the room and Firefox joins video both works in both directions
- if Firefox create the room and Chrome joins only a single initial frame gets send by Firefox to Chrome (video from Chrome to Firefox works fine)

Firefox 50, 49 and 48 are not affected by this.

Continue tracking in the Firefox bug for now.

Sorry the problem I saw earlier were most likely caused by trying to share one camera between Chrome and Firefox. With dedicated cameras per browser I'm not able to repro the problem.
