On Poulsbo? Yes.

So far, only the following codecs are supported at VLD level: MPEG-2, 
MPEG-4, H.263, H.264, VC-1 (and WMV3 variants). I don't think there are 
more to support. However, for completeness, you are also welcome to add 
MPEG-2 acceleration at motion compensation level. ;-)

The VA API patches are not fully integrated yet into the FFmpeg SVN tree. 
In the meantime, you can get recent enough bits here (as a large patch 
against FFmpeg SVN): 

This depends on this version of VA API:
This is also getting integrated upstream. Actually, most of the patches 
were integrated today.
