That should work. Try updating your libraries or try disabling two pass encoding for your preset.

I have the same problem. Runing Vide0-7.x-2.x-dev from May 2(?) was working but upgrading to video-7.x-2.7 caused webm to be without video.

Disabling two pass solved the problem.

Until somewhere between 7.x-2.6 and 7.x-2.7, two-pass encoding was never working for FFmpeg in the first place. I have disabled it for Ogg Video, but perhaps I should have disabled it for WebM too. I will look into it.

I have found the source of the problem, I will update the module soon.

The fix has been committed to 7.x-2.x. Within 12 hours there will be a new 7.x-2.x-dev build that should allow WebM encoding with two-pass enabled.
