FIXED: VLC 1.1 doesn't play .webm while totem and mplayer do

Looks like VLC isn't built with libvpx support even though that lib is in Arch's repo already and according to the VLC website VLC 1.1 should support .webm.
The error message VLC gives is,

No suitable decoder module:
VLC does not support the audio or video format "VP80". Unfortunately there is no way for you to fix this.

sound works so the demuxer seems to be working.

i guess is a bug in vlc. our ffmpeg has built in libvpx support

> ffmpeg -codecs 2> /dev/null | grep -i vp8
 DEV    libvpx          libvpx VP8
 D V D  vp8             On2 VP8

> ffmpeg -formats 2> /dev/null | grep webm
  E webm            WebM file format

One would think announcing this as a major feature would have them test it once^^
Maybe someone with VLC on some other OS I won't name can test it, just to make sure. You can get a test file at http://www.webmfiles.org/demo-files/

ffmpeg now has two decoders for VP8. one native and one a wrapper to libvpx. maybe that's confusing vlc

in fact is an old ffmpeg version that doesn't have the native vp8 decoder.
