You are right. It is not enough to just stop playback, you have to quit out of the player entirely and restart it.

What is the advantage of D3D11 DXVA? Faster rendering for rigs that support it? Does it improve image quality?

There shouldn't be a quality difference in any of the decoding types. It's likely the benefit is resource utilization.

DXVA native with nvidia cards can result in quality loss if it is used with madVR for example. D3D11 doesn't have this problem.

on top of it D3D11 supports headless mode which is very useful for PCs that have a iGPU with very good codec support and a dGPU with not that good codec support.

Well that's good to know about headless. I see I've been away from these things too long. LOL. D3D11 support seems very good to me in my latest tests with my new 1060. I had no issues with 3D playback which is awesome.

I am sorry if its a stupid question, but I can't understand how can I enable the D3D11 support in LAV Filter, I have only DXVA2 (copy-back) and all the others except D3D11?

What I am doing wrong?

I thought I did! Which is the latest versions, just to make sure?

Thanks for the help by the way.

D3D11 DXVA it is a miracle, just do not understand how deinterlacing algorithm qualitatively?

with D3D11 native deinterlancing is job of the renderer and madVR doesn't support deinterlancing with d3d11 yet.
d3d11 copyback should work with lavfilter software deinterlancer just select the GPU and you will get copyback.

i have a problem with cpu usage.

i use dvbviewer with lavfilters vid dec and ffdshow raw filter for subtitling.
when i playback x265 stuff (720p 10bit), cpu usage is normally around 20%.
but sometimes it goes up to 50%.
then i have to do a graph rebuild and it is @ 20% again.

with x264 i never had such a problem.

Sounds to me like at some point, an additional filter gets enabled which was not active before, or the rendering process was forced to switch to a compatibility technology from this moment on. Just guessing though...

i saw that "embedded subtitles" were enabled in ffdshow.
i think this was the reason.
now its disabled and will see if it happens again in the next days.

2) native D3D11 DXVA hardware decoding:

This is a new feature nevcairiel (thanks!) and I have been working on. Basically it "replaces" the old native D3D9 DXVA hardware decoding with a new D3D11 solution. (Well, D3D9 DXVA is still available.)

- image quality is now always identical to software decoding (unlike D3D9 DXVA)
- now AMD 10bit HEVC hardware decoding works, too
- might be ever so slightly faster (with potential for future improvements)
- self-made decoder<->renderer interface should be more stable
- probably requires Windows 8.1 or Windows 10
- I've not implemented DXVA scaling yet
- I've not implemented DXVA deinterlacing yet

Software decoding still has a small advantage, though: The madVR features "forced film mode" and "zoom control" currently only work with software decoding (or copyback).

5) support for AMD's private HDR switching API


AMD's private HDR switching API seems to work well, but it's more limited compared to Nvidia's API. AMD's API only works if there's active fullscreen D3D11 video playback (or gaming), which also has to be 10bit! Otherwise, the AMD API will do nothing. Consequently, madVR will switch to passthrough only in the moment when you go fullscreen, and only if you configured madVR to use 10bit D3D11.

Nvidia's API also works in windowed mode, and also with 8bit D3D11, even with D3D9.

You can't use software deinterlacing if you use D3D11 native mode. If you use d3d11 copy-back (by selecting a specific decode device), it should behave just like dxva2 cb.

ah, . i miss them. didnt know theres that option.
cheers.

edit: weird, after choosing hardware device, i play video and there they are, playing at 60fps, then screens blinking a couple of times and d3d11 revert back to automatic and fps turns back to 30fps.
edit2: it seems even without playing video, for instance, closing mpc-hc after applying the chance, revert them back to automatic
