Rendering webm produce somehow corrupted video files, that are not playable in Firefox. Even not in Firefox v.27 under Windows. You can reproduce it always for example with
avconv -i video.mp4 -vcodec libvpx -b 700k -r 25 -acodec libvorbis -ab 128k /tmp/video.webm
and then open video.webm in Firefox. It can not be even recognized as video file. It is marked as audio file. If you try press a few times on the progress bar somewhere inside of this stream it starts to play.
I have tried some webm video that I have rendered some months ago, all were o.k. Also rendered webm videos with Mediacoder http://www.mediacoderhq.com/ are o.k.

There is very similar bugreport in upstream (but quite old already)
https://bugzilla.libav.org/show_bug.cgi?id=341

libav is actually version 9.11-1
