This is still happening with native mode and v0.92.3. But now it's random and when it does happen the video does not recover, it just freezes and I have to End Task MPC-BE.

How do you access a DXVA texture from Vulkan without workarounds like Copy-Back?
D3D11VA is awesome, once madVR fully supports all its features (it's still missing deinterlacing) we'll have at least the same or better performance as DXVA2 Native, with better quality.

He doesn't seem to realize that Microsoft is reponsible for unified video APIs on Windows, and not developers like nev or madshi.
Not to say that LAV Filters and madVR are and will be Windows exclusive anyway.

Unfortunately since Jriver 23, this rarely if ever works. madVr won't switch out of windowed mode. If I use the hotkey to try and kick it into exclusive mode it merely states "exclusive" but does not actually switch.

This is only for 3D MVC playback; if I playback 2D, it does indeed switch.

In JRiver MC22, this was not a problem at all.

JRiver folks seem to not care about this issue; curious if anyone else has had problems with this combo and if not, perhaps you can share settings.

Thanks in advance. Suspect a JRiver MC23 + madVr integration issue, but have no hard evidence of that
I've not had this issue with my 1060 and the latest nVidia drivers. That being said, I'm not using FSE as much these days as I was in the beginning when I first got the card. When I get a free minute I can test this out and reply back. Just an FYI, I've switched to the 64 bit builds, not that it should be relevant to your issue. Although, who knows, worth trying?

EDIT: P. S. Do you have 3D enabled in Windows display settings? If so, you may try turning that off and letting madVR turn it on when needed. There's been some screwy issues with that lately and I ended up disabling it in Windows which solved the problems I was having.

I will admit that I don't know much about the 4k space and HDR yet, but, I do know that MS just pushed an update recently to Windows that defaults HDR to off. You probably know this but just in case, make sure it's enabled in Windows. If you have, my apologies for butting in where I don't know what I'm talking about. LOL

@Madshi

Still does not auto switch to HDR on AMD. I have to switch manually in Win10 display settings.
Still does not work in fullscreen exclusive mode (washed out colors).

EDIT: Just need to add that if I have 10 bit on in MadVR and 10 bit set in AMD display settings colorspace is wrong when playing 8 bit videos (everything is oversaturated). I have to manually set either the AMD display settings to 8 bit. Or MadVR to 8 bit in the display properties or use BT202 in MadVR calibration settings (close but not perfect doing it that way though) when both AMD and MadVR are set to 10 bit.

I need for MadVR to do all this switching automatically.

For me, deinterlacing is working if i use DX11 CB.
In LAV use DXVA11 and choose you GPU -> CB
Automatic -> native

It should be off, if i quote Madshi right.
If its on all non HDR Material has wrong Color.

It was always off for me. Anyhow I do not want HDR always on as it will completely screw up non-HDR video colorspace. I only want it on for HDR video playback.

The other issue is if I set my display to 10 bit then 8 bit colorspace gets screwed up in MadVR. Really I need MadVR to do all the switching for 8/10 bit and HDR sources.

That makes complete sense. Just like having madVR switch on 3D instead of leaving it on in the OS. So yup, that does make sense to me. All things I'll need to learn when I eventually move to 4K. Just don't want to give up my 3D. SIGH

I'm on Windows 10 Creators Update; yeah - 3D is set dynamically (so typically off). I also am trying the 64bit build.

It's weird that for 2D, FSE kicks in but for 3D it does not. Dropping back down to MC22, and it works fine, 2D or 3D which leads me down the path of a JRiver issue.

Do you have the nVidia 3D Vision drivers installed? Assuming that is needed of course.

With the nVidia card I've never had 3D MVC working without FSE

Thanks madshi for the new release. HDR in FSE is working again. I had skipped 0.92.2 because of this problem. Now that I have the latest release, i finally tried custom resolution. Works well, frpm one frame dropped every 12 mins to a drop once in 1.29 days!

Only problem now is that I don't get the OSD from my avr on the custom resolutions. Guessing its because the new resolution is not exactly 23/24p?

Is the current Afterburner release able to display it's Statistic server OSD successful into madvr D3D11 ?

i guess i need to update for Pascal anyway now to get rid of this hysteresis occurring now inside the semi passive cards Design

i thought i get away from updating it if it wouldn't work anyways no real reason for it but thinking about it to access the nice new power curves to maybe be able to fix the hysteresis (by undervolting to get lower heat dissipation for the fans to turn on, off, on, off,on off as crazy as they do currently) here i wont have another option anyways as to update it i guess if i want or not.

I could lower madvrs render overhead maybe a little further i guess but that wouldn't be really the right way to tackle this, last option i would try.

ultimately i want to get rid of this

http://leakimg.com/oJ9DNu8/image.png

you can see how the hysteresis starts to creep up reaching the starting point @ 52-53°C then it starts to on,off,on,off

i want to avoid this without additional cooling which i think is unnecessary for this use case.

That's strange, not sure what's going on, I'll try to reproduce it here. Does this only apply to the Ctrl+J OSD, or also to things like e.g. the FSE seekbar or OSD texts like "Paused" etc?

would love to see this a) for general madVR speed and b) additional/different factors which possibly come into play with SSIM downscaling and NGU upscaling (if there are any compared to the general ones)

so a bigger card in the same series is generally faster for madVR and a bigger card is usually faster in everything.

Generally, game performance is roughly similar to madVR performance, with the weird exception of NGU which seems to be somewhat slower on Polaris GPUs compared to other GPUs.

3. Go to NVIDIA control panel - resolution not listed there.
4. Click on "Customize..." to get to the create new custom resolution screen.
5. You'll see the custom resolution that madVR had created - but it's unchecked (as in - disabled). Check it and click OK.
6. New custom mode appears on the main resolution selection screen (although listed as 24hz).
7. madVR now changes to that resolution when choosing 2160p23 regardless of the mode (FSE/D3D9/DSD11).
Interesting!! I'm not sure about the "unchecked" in step 5. I'm using the private Nvidia API to create custom resolutions, and I don't remember seeing an option there to "enable" und "disable" custom modes like that. But I'll double check.

I've been working with one of the MediaPortal devs on this. I think this will probably be fixed in a future MediaPortal version.

After NGU upscaling it's probably less useful than when downscaling content directly, without having it doubled before. It's on my to do list to maybe add the LL info to the OSD.

No idea. Does it also happen with copyback, or with other video renderers?

So how does it compare to older madVR builds? Is it the same as e.g. v0.91.x? Or was it better some time ago? If so, can you pinpoint the exact version where the issue was introduced?

It's been reported multiple times recently that especially Nvidia GPUs have trouble in madVR with the latest drivers when dynamically downswitching. Various users have reported that setting the GPU to "Adaptive" power seems to fix the problem. Maybe that will also fix your problems?

Am I doing something wrong? Any workarounds?
Are you sure that the media player is really totally closed? Maybe it's still lurking in the background as a zombie process?

If you're sure that the media player process is really completely gone then can you please create a debug log, zip it, upload it somewhere (don't attach here) and then link to it here?

Just to make sure that there are no misunderstandings:

Nothing has changed whatsoever about software decoding, native DXVA decoding, copyback DXVA decoding, D3D11 presentation/rendering, CUVID decoding, whatever. It's all the same and should still work as well as in older madVR + LAV builds.

The only thing that has changed is that there is now a new (and additional, optional) decoder in LAV called "D3D11". This new decoder is somewhat similar to the older DXVA2 decoder, except that DXVA2 is based on D3D9 while the new D3D11 decoder is based based on D3D11. You don't have to use the new decoder, you can stick to what you were using before, and nothing should change for you.

The reason why the new decoder doesn't work on Windows 7 is a limitation of the Microsoft Windows 7 APIs, even with the Platform update installed. The API limitation in detail is that madVR wants to access the luma and chroma channels directly in its pixel shaders, in order to provide exactly the same lossless quality as when using software or DXVA copyback decoding. But Windows 7 doesn't allow accessing the D3D11 decoder textures from within D3D11 pixel shaders. This feature was introduced only in Windows 8, and the Windows 7 Platform Update doesn't retro fit it, unfortunately. We've tried, but it simply isn't available.

FYI, when using DXVA2 native decoding, the same problem exists. It's not possible to access the luma and chroma channels directly because neither D3D9 nor D3D11 pixel shaders can access DXVA2 decoding surfaces directly, in any OS. So as a result, chroma quality is very slightly lower when using DXVA2 native decoding. That's one of the reasons why nevcairiel and I implemented the new D3D11 decoder - but sadly the benefits only work on Windows 8+.

Vulkan would have no benefit for me, considering that madVR is Windows, only. Most likely Vulkan GPU drivers will be less stable than D3D drivers for a while yet, so changing to Vulkan would only make things less stable than they are now. Going Vulkan makes sense mostly for devs who want to go multi-platform. Sadly, I don't have the resources to do that at this point in time.

This is still happening with native mode and v0.92.3. But now it's random and when it does happen the video does not recover, it just freezes and I have to End Task MPC-BE.
Could you please create another debug log for this situation, and ideally also a freeze report (Ctrl+Alt+Shift+Pause/Break)?

For testing i made a new Install Win 10 1703.
AMD RX560 @Crimson ReLive Edition 17.9.1
Lav Nightly 70.2-74
Madvr 92.3

Desktop is set to 1080 Full RGB 4:4:4
Win 10 HDR switch off
(when i use the Win10 HDR switch, TV is switching to HDR)
settings:

When Playing HDR content Madvr Overlay shows

One other thing maybe its the same Problem.
When i set manual 10bit my AVR info shows 10bit.
When madvr switches to 4k TV stream (Fashion 4K..), it (OSD) shows P010 10bit, but AVR info say 8bit.
Have you tried resetting madVR to default settings, and then re-enter the necessary settings like 10bit display bitdepth and D3D11 presentation? I'm asking because you have some somewhat unusual settings, like D3D11 presentation, but without the "present a frame for every VSync" option active, and with "present frames in advance" unchecked.

Also, have you tried FSE mode?

Which media player are you using? And you didn't remove the "amd_ags_???.dll" files, did you?

Your AVR only reporting 8bit even though the madVR reads 10bit is an ominous sign. It should really be 10bit.

Still does not work in fullscreen exclusive mode (washed out colors).
See also my reply directly above this one.

Washed out colors is with HDR switched on or off in the win10 display settings? If on, then it's a GPU driver or OS problem, nothing I can do about it.

I have to manually set either the AMD display settings to 8 bit. Or MadVR to 8 bit in the display properties or use BT202 in MadVR calibration settings (close but not perfect doing it that way though) when both AMD and MadVR are set to 10 bit.
Is this once again with HDR turned on or off in the OS display settings? All hell will break lose if you enable that option, which is why I very strongly advice not to use it. The OS and drivers are terrible with that option turned on, nothing works correctly that way, in my experience. Not my fault. Please don't report bugs when the OS HDR switch is turned on. For now all problems with that configuration are very likely either OS or GPU driver issues, so I won't even try to look into it. Sorry. But Microsoft and the GPU manufacturers need to get their act together first to make the OS HDR option viable. For now the only thing we can do is to use the private AMD + Nvidia HDR APIs, which work much better, in my experience.

Only problem now is that I don't get the OSD from my avr on the custom resolutions. Guessing its because the new resolution is not exactly 23/24p?
Weird. Yeah, I guess your AVR doesn't like the custom modes. Thankfully it at least seems to pass it through properly!

Let me try and recap:

- "disable GPU gamma ramps" - unchecked. I can see the calibration is being applied and I am in windowed mode.

- MadVR switches to Exclusive: calibration not applied anymore ( I can see that visually)

- I switch back to windowed: calibration still not applied despite "disable GPU gamma ramps" is still unchecked.

- I check "disable GPU gamma ramps" in windowed mode: calibration not applied - as it should be, but it should have been applied before!

- I Uncheck "disable GPU gamma ramps" in windowed mode: now I see the calibration is being applied again.

- I switch back to exclusive mode: calibration is being disabled again (but "disable GPU gamma ramps" is still UNCHECKED).

I believe this is more obvious if your calibration is greatly different than your monitor native response - then you can clearly see the difference between calibration being enabled/disabled.
Thanks for your other advice: I already switched to 0-255 following a previous post.
All those settings changes are while the media player is still running, you didn't stop and restart it at any time between those steps you're rporting, is that correct?

Here's a screenshot of a sample of Life Of Pi, with all my mad VR settings.

My TV doesn't have a true 10 Bit panel, it has (i think) 8 bit + FRC. Maybe that's why colours are not right? Maybe I should set my display to 8 bit; madVR to 8 bit; disable dithering in madVr. And let the TV do its 8 bit + dithering when it detects the HDR signal? I'll give that a try.
Ok, thanks for the added details. I'm still missing some things, though. For several of my suggestions you said "I've already tried that", but you didn't say what the exact result of each of those tries was?

Generally, do you see any difference if you switch madVR's HDR settings back and forth between "let madVR decide" and "passthrough HDR content"? And is there any difference if you toggle between "send HDR metadata to the display" while "passthrough HDR content" is active?
