fast VC-1 Decoder [Archive]

I'm on a Core 2 Duo 2.0Ghz Memrom and as amazing as it seems, every attempt to read my blu-ray extracted vc-1 seems to face an incredible stuttering.

The thing that surprise me is that playing it from the "acer arcade deluxe" (which is a custom made power dvd it seems) make the movie play smoothly... is there any way to find an efficient and maybe dxva compatible decoder (for a nvidia 9600M GS) card ?

Try MPC-HC (http://forum.doom9.org/showthread.php?t=123537) or one of its standalone filters.

dxva decoding isn't supported for nvidia cards... It seems nvidia cards only got "motion compensation" based decoding (at least from the dxvachecker, I may be wrong) where each individual step is offloaded instead of offloading the entire bitstream.

And the ffdshow decoder included seems to result in tons of little green pixel frame for some odd reason.

Ah true, I had overlooked that as I don't have an Nvidia card myself. Tried WMVideo Decoder DMO?

The libavcodec vc-1 decoder isn't half bad (without GPU acceleration, it's what you get with MPC-HC, I think). WMVideo Decoder DMO is pretty good too!

dxva decoding isn't supported for nvidia cards...

You want a DXVA compatible decoder yet you know your video card is limited to MoComp?

DXVA doesn't mean everything has to be done on the card, it's also possible to accelerate just parts.

But MPC-HC's decoders don't support that (yet), since it's quite a bit more work than "simply" throwing the data at the card like it does now...

(Well mocomp and idct)

and I just tried ffdshow... using wmv9 as the decoder... and as amazing as it seems... it work far better than the WMVideo Decoder DMO...

Esurnir sure it does it uses 0 Postprocessing by Default :) though you can configure the WMO Decoder the same way, or use ffdshows internal postprocessing :)

If you have an nVidia, i'd suggest you to try Arcsoft.

Which software from arcsoft ? Cause I see a lot of "nero" "arcsoft" and other software but which one will give me the right directshow filter.

oh and :

VMV DMO max out my core 2 duo 2.0Ghz cpu on any blu-ray rip.

Current cpu usage with wmv9/ffdshow is a bit too high for comfort (at least compared to cpu usage from the top class h.264 codec I grabbed)

Arcsoft TMT.

Arcsoft TMT.

are the directshow filters installed as standalones at least ^^;, cause I got -great- filters in my blu-ray software player, but they are kind of... restricted to powerdvd....

Which OS are we talking about? Vista should automatically use PureVideo with the right NVidia card and current drivers. XP's GPU acceleration is quite a bit more fragile.

My two-laptops-ago Dell Pentium M 2 GHz with a NVidia 7600 Mobilty (IIRC) had no trouble playing back 1080p on Vista using the GPU.

Vista Premium 64 bit (soon ultimate), and I'm using the most current drivers :confused: . I see the capacities of it, just... not working ?

Does the screenshot of DXVA checker give any hint of what's happening ? Cause right now, for example DXVA checker tell me "not in use" with EVR. I use the 179.28 drivers, and Mediaplayer Classic HomeCinema when set to use WMV DMO on EVR custom (or not custom doesn't matter) on the dark knight from the start I end up seeing the glass explodes 2-4 second after hearing the shotgun shot.

And I know it's possible since the included blu-ray player (Acer Arcade Deluxe, or powerdvd with makeup) play the blu-rays fluidly without hogging the whole processor (it hog it a little but not at 90% or 50%)
