madVR - high quality video renderer (GPU assisted)

I have nothing against Kodi. I just think its video rendering needs to be updated to keep up with the times. I thought OpenGL standards were to blame.

Kodi under Windows uses DirectX (Direct3D), not OpenGL.
The problem with Kodi has to do, unfortunately, with too few Windows developers on board. Being open source, I hoped for quite a long while that somebody would fork it to something Windows only and be done with it. While I applaud the spirit behind some of Kodi's team decisions, for the longest time the Windows release has been reduced to something of an afterthought in many occasions.

The software is free, so they are free to do whatever they want and, certainly, lack of developers is hurting the Windows release.

After the whole DSPlayer debacle with aracnoz (the developer, I know you are familiar with him) being attacked for asking simple questions, I kind of lost faith in the whole thing. It's too bad that nobody is picking up the torch, really (save from aracnoz kindly providing updated builds from time to time).

Didn't know that. I think they still rely on the same video player code, but it could be different. The Windows release performs fine for me, but the lone Windows developer is definitely stretched for resources. I do know things are no better on Linux on the video rendering side. I was following the communication between the person in charge of the video player and a frustrated projector user who couldn't use his 3D LUT with Kodi because of the way it downgraded 10-bit BT.2020 inputs. Oddly enough, he left frustrated and left a link to madVR's HDR -> SDR thread at AVS Forums. I don't think he was very charming in his conversation. But he got the message across that he wanted more from Kodi. He probably could have left the madVR link out, though. The video player guy was actually trying to be helpful. Kodi isn't junk software.

Kodi DSPlayer doesn't really need a developer at the moment. It just needs someone to merge the Git to the latest Kodi master. I'll definitely try it myself if aracnoz doesn't provide an update this time. I just don't think I can move the player code around and still keep the player working. It depends on how many code conflicts there are in the already 6,000 new commits in Kodi master. It's more than just a simple merge.

DSPlayer is already a mature player with all the features it needs with new features being added all the time by LAV Filters and madVR. You are one of the users that has been there from the beginning.

so i recommend you to lay back set it to 8 bit forget this 10 bit garbage and just enjoy.

I am a mostly satisfied Samsung 120Hz owner. Granted my older plasma still has a better picture and Samsung is less interesting now that they don't make OLEDs.

Seems like a poor decision from a company that used to be associated with the best image quality in its heyday, taking over the throne from Sony. But, like you said, maybe no one will notice.

12bits works fine on my display (pixel shader, not passthrough), so I guess that's luck too as I don't need a 10bits mode. I didn't need it with the UB900 either, but I know many users did.

There is really little incentive for me to upgrade from 385.28, except if one day a new driver made no frame drop in 3D possible.

Did you have a chance to see if the levels are fixed?

Full -> Full -> Full has been working here for some time. I haven't tried any other configuration. This was verified with test patterns.

They know what they're doing..

There is no knowing if anyone has reported these issues to Nvidia. Although, they seem to be so incompetent at not bug testing anything that I wonder if these issues have been reported several driver versions ago and not fixed due to neglect.

I think so, too. But choices like that make me wonder if they are trying to cut costs to improve margins. If so, I'm not impressed.

* display peak nits edit control now accepts down to 80 Nits (formerly 120 Nits)

Is it just me or does this control now only accept down to 100 Nits?

It would be nice if this control accepted down to 50 Nits.

edit: The other issue I notice is that SD resolution deinterlaced 25i > 50p content is being displayed at 1080p60, where as HD resolution deinterlaced 25i > 50p is displaying at 1080p75.

Any idea why madvr uses is selecting the 1080p60 display mode for SD?

It's ALWAYS about margins. Their bet is on MicroLED. You won't see any TV OLED from them for the home market ever.

Did it before?

I'm reasonably positive it did not (with 0.92.12).

Easy thing to test my man, to confirm.

Doesn't work here on my JVC RS500.

In this build diffuse white is set to 100nits. I guess you can't set target nits below diffuse white, which makes sense.

[huhn]

full range is working perfectly here using 397.31.

is your problem related to SDR/HDR/3D all all together?

Hi Madshi,

want to Report 2 (maybe)"Bugs".

I am using Dvbviewer + Madvr + LAV.(all latest, LAV nightly)
Win10
AMD RX560 latest Driver (Friend has same Problems with RX580)
I am using the Madvr switching Option.
Profiles are: 1080p23, 1080p24, 1080p50, 2160p23, 2160p50, 2160p60

I let Madvr scale to 1080, only 4K i let switch to native.

First Problem:
On LiveTv 1080i50 -> 1080p50 (OSD reports Source 1080 50fps) good .
On records from LiveTv (1080) (OSD says Source 25fps) -> 2160p50 but it should be 1080p50.

Second Problem:
switching to 4K/60Hz
On Hotbird is a 4K Demo Channel 60fps 30Mbit+...
When i switch from 1080x to 2160p60 its working.
When i switch from 2160p50 to 2160p60 its not working, stays on 50Hz(source info 60fps).


Then i have seen another thing, maybe it helps you.

I dont use FSE, because way longer switching Times and Problems with Ambilight(Ambibox does not work all the Time with FSE).
When watching HDR Content, it works most of the Time.(enabling HDR)
When its not work (switching to HDR) the following does the Trick(else only reboot helps).
When playing content with HDR and switch to HDR was not working, i switch Player from Fullscreen to Window mode.
Then i can see in Window mode its HDR.(enable Fullscreen its goes normal..) now open AMD Panel switch from RGB to YUV and back. #
Now Window player is non HDR -> make Fullscreen Player -> HDR working

I have a GTX1080, first an AMD RX480 and I did not have these problems.

[stefanelli73]

.....I also noticed switching to the 92.14 of Madvr that nell'osd (ctrl + j) the bits always remain at 8 even if you selected 10bit in Madvr is a bug or is it a choice of Madshi?

[huhn]

windowed HDR is limited to 8 bit with nvidia because it is buggy with 10 bit.

10 bit FSE should work fine.

[stefanelli73]

...IN 385.28, but with the last driver this problem is not there, it reads 10bit regularly.

the problem with FSE is the black screen

Turns out I can do RCA Medium on 1080p30 now, every time I thought a GPU upgrade from my 7870 was long overdue madshi strikes again with a new build that does it all and then some
