Every now and then I convert one of my videos into webm-format for my 
server. Those videos are played by Firefox, Chrome and Opera. Today I 
converted another video in exact the same way and it is not starting in 
FF nor can I start this video mannually. No picture is displayed after 
loading. If I forward the video 3 seconds ore more a picture is 
displayed and I can start the video and it is playing fine.

So whats wrong? I tried converting a video already converted in December 
with the line from history of bash, so the same material is converted in 
exact the same way. result: video is not auto-playing anymore. So I have 
to asume, that a new version of ffmpeg (and/or libs) is the reason. Can 
anyone try the same and post the result here please. ..

Parameters are: -c:v libvpx -q:v 2 -s 720x576 -r 25 -aspect 16:9 -c:a 
libvorbis -b:a 128k -ar 44100 -ac 2
