VLC & WebM

I found on the net about the WebM recipe to play videos on YouTube HTML5
http://libreplanet.org/wiki/Group:PlayOgg/WebM_recipe

And wanted to try, but sadly i got this error:

[0x90acc5c] avformat mux error: unable for find a suitable output format
[0x91fae64] stream_out_standard stream out error: no suitable sout mux
module for

Will an upgrade of VLC correct this issue?
Thanks in advance.
