robothunter Wrote:That is what I use to think. I was downloading the latest version of ffdshow for my main computer and noticed that it now say's "Includes DXVA (Hardware acceleration)". So I downloaded it and Haali onto my Zotac ION N330 HTPC. Since I know that WMC uses that to play mkv files I loaded up a 1080p (6448kbps) movie with an ac3 5.1 soundtrack. It played smooth as silk with only 20% CPU usage. I tried Mediabrowser and got the same result. I was going to try and figure out how to implement this in Camelot but I had to go to work.

tiben20 Wrote:Ghizzu if you can give me enough information on how it could work and be worth it. Ill see what i can do. Here what i need First get graphstudio create or connect to mpc playing the http streams and print screen the graph. And ill need some specification on what you need to use in ffdshow. I really need the specific options you want to deal with in ffdshow. I dont want to integrate the entire options of ffdshow in the xbmc interface. There a lot of useless stuff. Just pm me with those info and ill see what i can do

Regarding ffdshow options, IMHO the absolute minimum is:
- Normalize audio
- Postprocessing (deblock/dering). This should be enabled on a per-codec basis, i.e automatically disabled for codecs that don't needs it (avc1/h264). (There's already a patch somewhere that enables it in DVDPlayer, waiting to be included in SVN.)
- DeBand filter (sometimes called gradfun). This reduces the "banding" effect in color gradients. It'so effective that sometimes you don't even need to enable postprocessing. It makes the image a little softer, though, so it should be enabled at will.

I'm just coming back from a test of this "new" gpu of mine, a HD 3650, using DSPlayer. Some of my movies are working perfect now, really smoothy thanks to the DSPlayer. But on the other hand, some of my h.264 moving are just not working at all with dsplayer. I read somewhere that the encoding has to fit GPU decoding standards, maybe those movies don't.

But, what exactly should happen when DXVA is just not capable of decoding the stream, is the dsplayer detecting it and switching back to software decoding ? Because I just get a scrambled screen, with no movement what so ever. Only the OSD and sound working well. There's just one of my h264 movies which still plays in software mode automatically.
Sorry if someone already came up with this issue, but the thread is just to gigantic to find it

Edit : I'm trying to reencode one of the non-working video using DXVA compliant parameters, so I assume I'll be fixed when it's done !
