Easy answers now. Difficult answers will come in the next couple of hours...

Anyway, I just remuxed a problem file to mp4 using mkv2mp4 and mpc-hc with madvr plays it without any problems!? I tried just remuxing the mkv using mkvtoolnix but the new mkv didn't play.

Any suggestions? What more can I test?

(running Win8 Pro, graphics card is radeon 6650M with catalyst mobility 12.10. LAV 0.54/MadVR 0.85.1, MPC-HC b6252)

EDIT: Never mind, looks like the remux only helped on one file...

EDIT2: All files work in ZoomPlayer Free 8.5!
This is really all very weird.

My output settings are following:
Output format in CCC is set to Limited RGB, madvr outputs TV levels and my TV is set to Limited RGB, basically everywhere is limited RGB.

When using dxva2cb for decoding, WTW and BTB are preserved, after switching to dxva2n, WTW and BTB are cut off, also when watching Black Clipping test video, 17-25 are not flashing anymore.

Ctrl+Alt+Shift+I shows in both cases: "source levels: auto detect (TV)"

When using EVR-CP there is no such difference when changing dxva mode in LAV decoder.

setup: HD 6670, Win7, madvr 0.85.1, LAV filters 0.54.0
Should be fixed in the next build.

Of course it only happens with windowed fullscreen, not exclusive mode.
In windowed fullscreen mode, madVR does not do any fancy stuff, so I don't think that's madVR's fault. I don't see what I could do to this change this. But it doesn't happen for me, anyway.

/edit:
Or is "[DXVA2]" only supposed to be added to the debug OSD?
Yeah, meant the debug OSD, will fix the changelog.

DXVA2 upscaling for a 720p file looks like bilinear. For SD it looks more like lanczos.
Interesting!

The "movie ... fps" information is simply what the upstream filter (video decoder or DVD navigator or whatever) is reporting to madVR. It's the fault of the upstream filters, not madVR's fault.

I think i read somewhere mVR will just pick the best deinterlacing algorithm available from the graphics card?
If you activate deinterlacing and don't force film mode then you'll get DXVA deinterlacing. madVR will always pick the best quality algorithm DXVA offers. I'm not sure if the GPU driver control panel options affect which algorithms are offered via DXVA. Maybe.

I don't know.

Correct, and it probably never will, for some internal technical reasons...

DXVA-Deinterlacing works as intended, no change in colors.
Interesting: using native decoding instead of copy-back lowers cpu load as expected but as well gpu load! Furthermore dxva2 upscaling has about the same gpu load as Mitchell-Netravali.
Thanks for the feedback.

EDIT: Doesn't work with DXVA2 Copy-Back or software encoding either.
It means that the DXVA2 APIs report failure for some reason. I don't know why. And it will be hard to fix without having access to such hardware. The same DXVA2 code in madVR appears to work fine for newer Intel GPUs, so I'm wondering if it's maybe a driver issue. But I don't really know...

Replied via PM.
