For regression testing it is however sufficient to hash the critical
structs passed to the VDPAU API.
I think I've posted patches for that already, but it was a bit of a
However what I'd really like but absolutely have no time for is a
software reference implementation of the VDPAU API.
This would allow testing on all FATE machines, regardless of what
hardware they have.
(as a first step such a reference implementation could also just
serialize out the API calls up to that frame, which would be
pure regression testing then).
