Am I to take this as DirectX cannot do that either?
That on Windows they have their own interfaces for full offload?
Bitstream Acceleration sounds suspiciously like bitstream decoding. Did you read the article?
Basically it has the features you state above and it is modeled on DXVA which is the directx video acceleration api. Now what isn't so clear is whether its modelled on dxva or dxva2, but that really isn't so relevant in this case.
and another thing:
"X-Video Bitstream Acceleration wouldn't be much of a challenge to reverse-engineer by the open-source community"
media player classic on windows has open source dxva bitstream decoding so I imagine that makes it even easier...Last edited by _txf_; 29 October 2008, 02:30 PM.

MPEG2? What about OGG, Dirac, Snow, and other open codecs that have no annoying legal issues with implementing acceleration for? Shouldn't those be a much higher priority? I mean, sure, many videos are MPEG as well as H264 and such, but some of the aforementioned open source codecs will greatly challenge them.
Unrestricted codecs FTW!

From those, XvMC already did idct, mc, and deint.

If they can get this out there, they will blow by Nvidia in a crucial segment: the HTPC one, because now folks can get small fanless motherboards and video cards and let the GPU do all the work.

Unless of course you were talking about support today?
