Updating the driver did not help, I can play a 10-Bit video with normal EVR only when I disable P010, I'm not really understanding the nature of the problem but then it don't seem important so no problem.

EVR-CP just blacklists P010, so it automatically falls back to NV12. Thats some kind of "working", I guess.

That works by accident, not by design. They pretend to send NV12 and then actually send P010, which is something you can do with DXVA2-Native, however if you try that on vanilla EVR, MPC-HCs EVR-CP, or madVR, you either get crashes (EVR, EVR-CP), or entirely broken images (madVR)

LAV is capable of doing that, but I decided against an output mode that fails in 90% of the cases.

Now it's clarified a lot for me.

Waiting for Intel's driver fix, then.

But using MPC-HC with EVR-CP and P010/P016 enabled, I still get black image.

MPC-BE crashes with EVR, but plays fine with EVR custom.

looks like they haven't blacklisted it.

I think MPC-HC only blacklisted P010 while Intel bugs out on P016, or something.

Is it technically difficult or impossible to blacklist P010/P016 using plain EVR, just like EVR custom ?

Because both MPC-HC, MPC-BE crash with plain EVR.

should be possible to block p010 and p016 when EVR is selected don't see a reason why this shouldn't be possible.

we are not talking about native DXVA right?

Right, I was talking in general.

For example 10 bit H.264 decoding doesn't have a HW decoder but suffers from the same problem.

It will be fixed in next nightly. The patch is ready, just hasn't been committed yet.

Of course, IMO the one that has created the issue (Nvidia, Intel) should fix the bug in their drivers.

But till then, hopefully soon, a workaround is an intermediate solution.

How to change Output Speaker Configuration form 5.1 to 2.0 with a key press?
I'm trying to have a button on my remote to toggle between two sound cards, one for 5.1 playback to the power amp and another sound card (built in on the motherboard) to playback to my headphones.
I've got a script that will move from one sound card to another using nircmd.exe, but I need to down mix everything to 2.0 for the headphones - unfortunately the drivers for the in built sound card won't do it.

I can use ffdshow to do it using registry loading, but this seems to be introducing too much delay in processing.
I like to do it in lav audio, but can't find a documented way to change the mixer tab settings i.e. Output Speaker Configuration using profiles or registry settings.
Any clues?

maybe EVR for MF can do this so this is maybe not even a clear bug.

Not sure if this is what you mean but I use this in my system http://theitbros.com/hotkey-to-switch-audio-devices/

To get full support for stuff like segmented linking or ordered chapters in MKVs, does one still need AV Splitter or latest LAV filters take care of that stuff too?

LAV supports them since 0.56.0 - which was released 2 years ago.

Don't get me wrong, the only reason I raise this is because lavfilters is awesome for everything else (just not WMV).

Any insights anyone?

Playback halts for a few seconds using LAV splitter. Seeking and playback is instant using Microsoft splitter or VLC.

+1

I see the pause too. MPC-HC is set by default to not use LAV Filters for WMV files also so I had to check that to see the problem.

It does not cache on disc, only in memory.
