Would that be the code in (master branch) src/gallium/auxiliary/vl?
Is there a way to try out the mpeg2 decoding functionality, for
example a version of mpeg2dec that uses this code? Considering I
have Radeon HD 5450, which I think is R800, would it work in

On a quick glance it appears that this could be used to support
XvBA once MPEG4 features are implemented, is that right? Would that
require changes outside the vl/ directory? Where / what kind?
