madVR - high quality video renderer (GPU assisted)

[huhn]

win8 can't do WFS 10 bit that's it FSE works totally fine.
madVR uses the API from nvida and AMD so the OS doesn't matter much for HDR what matter if there API are supported on other windows version then 0 which is still the case.

Hi Madshi, there were a few crashes since driver update to Intel-6618 related to the dll below.

callstack crc : $cc12cd00, $3d0d8150, $1a3e20d2
exception number : 1
exception class : Exception
exception message : Access violation at address $7ffe2a28b33d in module 'igd10iumd64.dll'. Write of address $4b886ce0.

[ryrynz]

That's all on Intel. Report it to them.

[madjock]

Is this not more of a Driver problem than a madVR one, multiple AMD/nVidia drivers have issues and everyone else rolls back or waits for a better driver ?

edit : ah beaten to the punch

Alright so troubleshooting this has finally completed on my saga of trying to get reasonable video playback again after switching from a GTX1060 to a RTX2060

I can disable more things to lower it further and it doesn't seem to improve it. Yes smooth motion is on in the when needed but should be needed her 23fps content and display changed to 24fps. It doesnt show dropped or duplicated frames for how stuttery it is. Previously had the 1060 in there no real improvement going to the 2060.

Ideas on troubleshooting this would be helpful. I have tried:

using different decoders in lav filters. Anything other than CUVID just seems worse
MPC-HC versions 1.7.13 and 1.8.4
madVR versions 0.92.14 and now 0.92.17
upgraded the GPU
lower settings from NGU to superxbr to jinc
increasing buffer from 8 to 16 (though im not sure if 6GB vram is enough for this)

I have not completely wiped my madVR settings to see if it does it from scratch since I thought I would post here first to see if someone has ideas.

The stuttering has mostly been fixed I just get a little blip every now and then say every couple minutes at most. some time during fast actions or pans. I'm not using smooth motion just matching frame rate could this be buffer related? This seems more frequent than the 1 stutter every 4min or so that the madVR UI is suggesting.

I did fix exclusive mode as well.


both the stuttering and exclusive mode seem to have been related to having HDR enabled in Win10 at an OS level.


I have not yet tweaked scaling algorithms or anything like that yet. Just on default settings.



When playing back 4K HDR BD content I'm still getting stuttering on pans that should be smooth. This is with HDR turned off at the OS level and HDR set to pass through. Colors look very muted So I don't think it is actually doing HDR with this setup.

So its looking like most of my issues have been related to HDR.

That setting was supposed to be flipped to on


I tried forced V-Sync with HDR content with HDR enabled at the OS level and still stuttered. I forced Vsync to On for MPC-HC as well as my madVR folder.

With these forced on and OS HDR disabled the playback is much less stutters but it is still stuttery and the colors are all muted so The display either sint getting HDR or doesn't know it is.

This testing was done playing back 4K HDR BD Content

Thanks to the below chart I no longer have stutter on my HTPC playing back even 4K HDR BD content. 418.91 did indeed fix my issues and large pans in GITS live action and Bladerunner 2049 are not buttery smooth. No random hiccups from 1080p playback on my 4K screen either so Ill now be able to start tweaking my actual settings which I thought were the issue all along. Thanks to the community for the help as always. Suck when I try to chill after work just to have the thing that's supposed to provide relation pissing me off.

Last thing to note is that with Windows 10 OS HDR enabled I still cant go fullscreen exclusive.

419.67 CRD 2019-03-20 stuttering issues

419.17 GRD 2019-02-22
418.91 GRD 2019-02-14 NO stuttering issues

Did anyone test 419.17 about the stutter issues?

Glad to hear going back to 418.91 fixes it. I can totally relate. I'm stuck with a 1660gtx that stutters no matter what. Much less with vsync on (every 2-3 min now), but unfortunately I can't go back to 418.x since they don't support the 1660 . I'm really hoping Nvidia figures out what the issue is, but I'm afraid I may have to dump my 1660 if it doesn't get resolved soon.

I have a problem which is likely a driver or OS problem, I just want to ask if it's known here and where I should report it, NVIDIA has a support forum, right? I reported it first to mpv, and they told me to test madVR. After I told them it's not working in madVR too they said it's a driver or OS problem. It happens when I do the following:

using Windows 10
using NVIDIA GT 1030 card
dual monitor with duplicate mode
use d3d11 which mpv and madVR use by default
use fullscreen windowed mode

The second screen is broken then, horizontally stretched showing only the left side of the image and everything is green.

[huhn]

working flawless here.

cloning two 1080p screens
windows 17134
1060 419.67
d3d11 windowed and FSE which isn't the default madVR option.

[stax76]

Thanks for testing. I've forgotten to mention that it happens only in full screen mode. I'm using the latest Win 10 and a driver installed about 3 weeks ago, screens are both UHD.

[huhn]

i tested FSE and WFS.

anything else that comes to mind?
screen scaling?

[stax76]

Maybe it happens only with UHD but it could be anything, much likely it relates to d3d11, when I use gpu-context=angle in mpv then it's fine. When I extend the screens instead of duplicating it then it's fine as long as I start the player directly on the TV, yesterday I started the player first on the desktop (because the TV wasn't on yet) and moved it to the TV screen afterwards which caused the problem to appear.

[tp4tissue]

Is there a way to change zoom percentage ? for when I want to squish or expand images on CRT ?

[Asmodian]

That is the player's responsibility, madVR will render to whatever size the player asks for.

Zoom Player is very good at that kind of thing.

[SirMaster]

So I can set a lens memory on my JVC when a video starts to play.

But how can I set a lens memory when a video stops playing?

I want to revert back to my main default lens memory when playback stops and only be in my special video lens memory when I’m playing any video in madvr.

Sorry guys, terribly busy atm. Just to let you know: My Nvidia driver contact just informed me that the HDR passthrough problems (not always engaging, and incorrect metadata) should be fixed in the next bigger driver release.

[Ver Greeneyes]

FWIW, I also noticed this line in the information for the latest cumulative update for Windows 10: "Addresses an issue that prevents users from configuring their screens for high-dynamic-range (HDR) video playback."

What exactly that fixed or if it'll affect madVR in any way I don't know.

[huhn]

should be unrelated because that's about the windows API.

This is great news! Thanks for taking the time to let us know
