Hi there,

I've tested VC1 (BD) playback on MP and found out that Cyberlink Video Decoder isnt using it's dxva capabilities in MP
It's working in Graphstudio and MPC-HD and anywhere else. I made all the settings and double checked the registry but no success. I allways was a bit chary about bug reports since I'm using an unsupported setup (MDA**).

I still hope that you can help me since I'm out of ideas ..

A second test with original build 1.2.2 Final has the same issue

I think you mean MePo does not use HW decoding for VC-1

I can confirm this issue, by some reason, PDVD decoder always fall back to SW decoding, but only for VC-1.
No problem with h.264.

I have add this part of code to select DXVA/HAM/SW maybe i did something wrong.
So it only happen on VC1 and H264 is ok (that mean the registry is set correctly right ?)
Thanks

Yes. h.264 is OK, VC-1 fall back to SW.
I tested to rename Graphstudio to MediaPortal.exe to confirme that registry are set correctly. And DXVA was working for both, so it must be something in MePo.

Thanks,
I have test VC-1 in MePo (my vc1 build) on MyVideo with mkv and m2ts VC-1/VC-1i and DXVA stay on setting (i look by setting up ffdshow video as post process and like this i can look the cyberlink codec).
Going to try on 1.2.2

I've tried to add the key clvc1dec with the subkey mediaportal to the registry and then added both dword values but no success.

Start video in MePo, connect graphstudio, open Video out pin in PDVD decoder and look for "BiCompresion". There will be YUY2 if DXVA is not in use.

Damn !
i have : 0x32595559 [YUY2] @ biCompression
Good find Hoborg
Will going to see why

Ok i'm an idiot lol i have ffdshow video in chain lol
Going to try without

 

[Sebastiii]

Ok i have 0x41565844 [DXVA] on both mkv / m2ts / VC-1 / VC-1i
Tested on VC-1 Build let's try with 1.2.2
