Does anyone know the answer to johnc's question:
What AMD GPUs can decode Hi10P videos with its dedicated hardware video decoder (ie. UVD)?
Or am I misunderstanding the article and this is just to put in hooks so when GPUs have hardware video decoders that support Hi10P, VDPAU will be able to make use of it at that point?

You guys aren't getting what johnc is asking. It's since when do these dedicated decoders decode hi10p and why isn't it advertised? Because common knowledge is that hi10p isn't supported.
So again: Why isn't hi10p support advertised anywhere? And where a list of which hardware exactly supports hi10p?

The "fun" part of this news is that according to an nvidia engineer here: http://www.nvnews.net/vbulletin/show...hp?t=164684#12
it is not supported by the decoding hardware of nvidia cards.
I also wonder why an ASIC is present on Radeon-cards and this was never advertised. Some year ago I was specifically searching for this to select hardware capable of this - but I could not find anything.

I think the marketing department never really understood that anime fans would kill for this feature...

If support is there, it must be fairly new. And that's a big "if", I'm skeptical that there's support on *any* hardware, because if AMD added hi10p but didn't mention it to anyone, that's quite high levels of stupidity.
It could be an limitation of DXVA on windows. This could mean that what everybody assumed was hardware limitation was in fact just software limitations.
The only known fact is that hardware from nvidia does not support hi10p in hardware.
Looking at http://www.amd.com/us/Documents/UVD3_whitepaper.pdf it does mention 10 bit colour processing. Considering this and the fact that ATI was famous for their video support, I would not be very surprised if all versions of UVD turns out to supports 10 bit hardware decode.
