this could mean we will be able to apply all post processing filters after utilizing DXVA decoding. (except maybe the resize filter)
we're still not sure if this could be applied for DXVA 1.0 as well, we do have some interesting ideas.
albain has volunteered (again) to try and implement it.

p.s.
the memory bandwidth required to process 1080p24 that way seems easily obtainable. |
keep in mind this only works for DXVA2 and thus vista and higher, so DXVA1 will not work.(although some things could be done in shaders)
