madVR - high quality video renderer (GPU assisted)

The only thing we know for sure is that neither win10 nor Nvidia output perfect gamut metadata. Maybe there's a small error, maybe they're completely wrong, we don't know that for sure right now. I suppose the Vertex isn't able to show the raw hex bytes?

See my post above re which values the Vertex supports.

The Vertex of course can show the raw metadata, just not on the OSD where it's more useful to have it decoded for human consumption

In any case, there is ZERO reason for any software to change the metadata in pass-though mode. I have validated playing the files with the UB900 that the metadata was present and correct in the files, so both MS and nVidia should not touch it in passthrough mode.

I'll post the full HEX for both modes when I find the time.

Full hex would be interesting. I should be able to decode it, if you can post the correct hex data for the UB900, too.

Yes, this is what I was planning to do

So here we go, starting with the Exodus trailer played by the UB900:
87:01:1a:91:02:00:c2:33:c4:86:4c:1d:b8:0b:d0:84:80:3e:13:3d:42:40:b0:04:c8:00:00:00:00:00

This is decoded by the Vertex as:
Exodus: ST2084 max 1200/ min 0.020 MaxCLL/FALL 0/0 mastering display primaries DCI-P3 white point D65

Playing the same file from the HTPC, with OS HDR Off:
87:01:1a:79:02:00:d0:84:80:3e:4c:1d:b8:0b:c2:33:c4:86:42:40:00:00:b0:04:c8:00:b0:04:b0:04

This, as already reported, is decoded by the Vertex as:
Exodus: ST2084 max 1200/ min 0.020 MaxCLL/FALL 1200/1200 mastering display primaries nothing white point nothing

Finally, playing the same file from the HTPC, with the OS set to HDR On:
87:01:1a:fb:02:00:d0:84:7f:3e:c2:33:c3:86:4b:1d:b7:0b:12:3d:42:40:e8:03:2c:01:e8:03:14:00

This, as already reported, is decoded by the Vertex as:
Exodus: ST2084 max 1000/ min 0.030 MaxCLL/FALL 1000/20 mastering display primaries nothing white point nothing

Note that if I stop playback when the OS HDR is set to on, the metadata stays the same, which proves that it's not content related and the the OS simply sends a fixed metadata whether content is playing or not.

If I stop playback when the OS HDR is set to off, the Vertex correctly reports no HDR metadata.

Hope this helps, I don't have the time to check the HEX data myself, please let me know if you find any error in the Vertex decoding vs the HEX data.

[Manni]

Forgot to say, ignore the first 4 hex values, I don't think they are part of the header, the header starts (I think) at 02:00 etc but I don't have time to check, let me know if you struggle and I'll take a closer look.

On HDR not working. I have a AMD MSI Radeon RX 480 8GB Gaming X. I am using the latest driver 17.8.1 (older drivers made no difference anyhow).

It's been the same way since HDR was introduced in MadVR. It only works with HDR enabled in Win10, FSE disabled and by clicking on certain system tray icons like MadVR and a couple of others. If I hover above the icons it works for a few seconds then goes back to being washed out. I have to click on the MadVR icon to bring up the menu options for it to stay in the correct color output. Also as stated the auto switching Win10 from SDR to HDR mode is not working.

Has anyone else successfully got HDR working correctly with auto switching in Windows using AMD GPU's?

I also have aufkrawall's issue with wrong 'dark' colors decoding HEVC using DXVA2.

[madshi]

@Manni, can you please post the hex data with this test build for both HTPC options?

@oddball, do you have D3D11 presentation activated, and the display properties set to 10bit? Only then dynamic HDR switching works with AMD.

Hi Madchi,

in the last couple of years i have reliably used your program as an addon for MPC-HT, and thank you for the great program you made !

but since recently doing a repair on my win7 (64 bit) OS i am having problems re-installing madvr

am using win7 64 bit with an i7 , 32gb ram with amd 5770 card

MPC-HT runs fine (64 bit), and my amd catalyst drivers are correctly installed

when i run the installation of madvr it seems to run correctly (the usual dos box opens with the brief msg about file locations), but madvr doesnt show up on my right click options in MPC-HT anymore

i vaguely remember a few yrs ago having a similar problem (which i resolved, and it was something simple iirc) but i cant find any problem solving information text file online right now that might help me solve this. is there a Q&A file for errors i can check somewhere ? or some advice you can give me on what to check ?

[huhn]

if you mean mpc-hc with mpc-ht you have to select madVR under options -> Output -> DirectShow video -> madVR

But of course. Otherwise HDR would not work correctly even by clicking on the MadVR icon. I have tried with copy back and the new D3D11 options. Something is not working through the entire chain.

Note: Setting HDR to on in Win10 display settings causes the LG OLED55B6V to switch to HDR mode and the HDR logo displays on the TV. But simply playing back an HDR video results in washed out colors. FSE has to be disabled and I have to click on the MadVR icon to get the correct color output and brightness levels. If I leave HDR off in display settings it will not auto switch to HDR.

Have you set MadVR as the default renderer in MPC? Did you run the install.bat as Administrator?

[zapatista]

thanks huhn !

it was indeed as simple as that, another RTFM error resolved

[zipeldiablo]

Hi guys, is there a compendium or an up-to-date tutorial somewhere on how to customize madvr + mpc-hc + lav filters (from what i found online those are the required tools?) in order to get hdr from hdr content (tried passthrough and stuff and colors are washed out) and upscaling properly non 4k content for a 4k oled hdr screen.

Sure, here you go

With test build, here is what I get with OS HDR Off:

87:01:1a:29:02:00:c2:33:c4:86:4c:1d:b8:0b:d0:84:80:3e:13:3d:42:40:b0:04:c8:00:b0:04:b0:04

The Vertex reports:
Exodus: ST2084 max 1200/ min 0.020 MaxCLL/FALL 1200/1200 mastering display primaries DCI-P3 white point D65
so all correct now apart from MaxCLL/FALL which are not supported yet by MadVR.

With OS HDR On:
87:01:1a:fb:02:00:d0:84:7f:3e:c2:33:c3:86:4b:1d:b7:0b:12:3d:42:40:e8:03:2c:01:e8:03:14:00

This is the same MS fixed metadata as with the non-test build, so the Vertex decodes the same:
Exodus/Anything/Nothing playing: ST2084 max 1000/ min 0.030 MaxCLL/FALL 1000/20 mastering display primaries nothing white point nothing

[Manni]

I also tested the two other files (Neo fire and RM Brightness) with OS HDR off, and all the metadata is now reported correctly (to the exception of the not-yet-supported MaxCLL/FALL of course) with the test build.

i dont have a HDR switch in my Win 10 Version.. its the actual 1703 Build.. :/

Not sure what's wrong. You could try to remove and totally clean the AMD driver installation and then reinstall it. If that doesn't help, maybe an OS reinstall is the only solution. Not sure what else to suggest.

Which GPU?

Great!

Now I wish you had an AMD GPU, so we could test that, too...

I still have my HD7870 but I don't have the time to swap it with the 1080 Ti at the moment. I'll see what I can do and I'll let you know.

gtx 950

[huhn]

and you have an HDR10 TV ?

I'm not sure if the 7870 can do HDR at all, but it would be interesting to know!

Good question. Another question is if the HTPC is directly connected to the TV, or maybe there's an AVR in between? If the AVR doesn't support HDR, the HTPC might not know that the TV supports it.
