madVR black screen - no video [Solved for some by rolling back Windows update]

You may also want to generate some madvr logs to compare the difference, use the 'activate debug mode.bat' file in the \plugins\madvr folder to turn on logging. This will generate a madvr.log file on the desktop.

As a further aside you may be chasing a quite short lived problem, as I understand it Windows Build 1909 (the H2 build) is nearly upon us, it is in Preview right now. It may not show this problem at all (and is supposed to fix the banding issues of 1903).

Good luck

Terry

If you want to progress the issue, rather than just avoid it by uninstalling KB4512941, compare the DirectShow Graphs between MPC-HC and MC using RO HQ. Maybe there is something obvious.

Ok, in case I could not solve it in any other way I can uninstall the update. Can you guide me on how to compare the DirectShow Graphs, where do I look for them?

Thanks in advance.

Things to keep in check … JRiver uses its own copy of MadVR (located in [user]\AppData\Roaming\J River\Media Center 25\Plugins\madvr)

Check whether MadVR settings in JRiver (access through MC options) matches MadVR settings of your MPC-HC (access through MadVR tray icon on desktop) ... also check version of MadVR for both

PS. I also notice in your MadVR setting [devices]->[display mode] … you have 2160p24, 2160p50, 2160p60

you should really match all refresh rate as 24 is not 23.97 … so something like

2160p23, 2160p24, 2160p25, 2160p29, 2160p30, 2160p50, 2160p59, 2160p60

PSS. screenshot of your Nvidia setting will be helpful … one of [change resolution] stuff on bottom (output format, color depth, dynamic range, etc) … one of your multiple monitor setup

I will try adding more options for different refresh rates, I think it does not matter much using VideoClock, correct me if I am wrong.

I checked and the settings in MPC-HC matches exactly the settings in JRiver.

Yeah, I know it is very strange and could be resolved in a future update without any intervention. I will try activate logging, but I do not know if madshi will have time to see it, he is focused on Envy for now.

Thanks for your help Terry!

In MC, just play the video, which in your case will show a black screen, then right-click anywhere on the video, select "DirectShow Filters > Copy graph info to clipboard". Then paste the result somewhere. It should look like my sample above.

I don't know with MPC-HC, but I assume there is a similar function somewhere.
