Just testing it, my 8800gt doesn't need it but my Asrock 330 will love it!
Let us know how the ASROCK does.

Thank God I have a spare copy of Windows 7 lying around... Upgrade to come!

I LOVED the PQ of dvdplayer , has it changed with the implementation of DXVA? Nothing washed out etc
Reason I ask is because Tibens build w/dsplayer , the PQ was washed out, and just bland overall. DVDplayer has always been a perfect source. Hope it stays that way because my CPU usage has always been 50% max on any 1080P MKV, so i never needed DXVA on my beefy system!
PQ IMO is far better using DX....far sharper....looks great. Now if only I could find a way to register coreavc and for dvdplayer to call it....oh well...lol
Great work!

Great!! Can't wait to get home and try it out!
Again...Great work from all the people involved....the best HT experience available yet.

Ok - would someone be so kind as to lay out what the benefits are in a general sense? Let's pretend I'm new here (heh) and that I have XBMC running on an XP box with current hardware (lets say an ATI 4550 HDMI card) and beside it, I have XBMC running on a Windows 7 box... With the different programs running (XP with 'basic' and Win7 with 'DXVA') what would look different between the two?

it's all about using your gpu to decode rather than the cpu. if you cpu can decode your shit without struggling, zilch is to be gained.

I absolutely LOVE the way you post. You answered my question without a hint of BS or extra fluff.
Thanks!

question: how do i know if DXVA is working? DSplayer gives you a different overlay when you push O, but i can't see anything to that effect on the nightly i installed...
I can see my HD4670 clocking up from the 165mhz it idles from to the working 750mhz, but i seem to get around 20% CPU use, while DSPlayer uses around 12-14%

i would love too see some benchmark test to compare both players

I can't win -
DSPlayer = Great video / no sound
DXVA = Green screen / sound

For all of you that ypu experience green artifacts in some of your files
and in quicktime trailers , you should all be aware of that this most
probably has nothing to do with xbmc itself . I bet that all of you that
having this problem , do own ati gpu's like me. Is well known that ati has
driver related dxva limitations. More specifically ati's drivers can't cope
with h.264 contect of any kind , if the reference frames in this content
is anything higher than standard bluray specs.
And nowdays there are a lot of files through the web that are encoded
beyond the standard bluray specs . All these files including full hd apple's trailers
will not play with ati cards. Well there going to play , but with dxva
off.
Apparently nvidia's cards seem to have no limitation such the above , in
their drivers. If you search the web you'll find a lot of information about the
above.
From what i've read , there is currently no intention from ati's side to
remove the limitation.
So what you're saying is that this green artifact problem will never be solved then?

Just a note.. The video scalers are doing nothing for dxva at the moment. I render directly to backbuffer so it's all how dxva processor scales at the moment.
And as i noted, it's still a WIP, untill i get some sort of detection working as to what will work and what will not it can't really be used auto.
Elis:
Any reason you say it's better to render to a texture then to backbuffer? we don't do any 3d stuff, and that would just be another step of renderering + to use any of the more advanced dxva processors, you'd have to render to a texture of backbuffer size.
It would allow the use of shaders to continue processing the video i suppose. But i'm not sure how big benefit that would be.
The late loading I would really like to avoid, but i can be convinced otherwise if it will fail totally on XP (which i suppose is likely now that i think of it). It's not that many functions that needs to be getproced.
- elupus - 2010-02-02
Also, debug logs with a short description of how it's failing would be appreciated. Don't post for many files thou as that is likely pointless untill i can sort our why it fails on my hw for so many files.

i'll be glad to run some for you if you send me instructions on how to run them
