Hi
I'm having some playback issues with madVR in Emby Theater. When I playback 4k video a black screen is shown and after 5 seconds the XXX comes with a failure. The audio is working fine. I have had this issue for 2,5 months now.

 

My setup is a nvidia 1070 and I have 2 monitors attached, one to my lg 4k oled and one to my AVR which then again is connected to the lg 4k. The reason for this setup is that my avr doesn't support 4k connection.
If I open the same video in MPC-HC with madvr then it works with out problem with the same MadVR Conf and version.

I have a similar situation with external *.srt files, but it is very unpredictable when it happens.

Please let me know if you need more information. Thanks in advance

What happens if you use Auto as the video renderer?

Hi

 

It works with auto, but then the system isn't using the madvr render, which I like. It using EVR - I think. I check with ctrl+j to see if the madvr stats was show to make sure it wasn't madvr

have you checked that your video drivers are up to date, as well as windows updates?

video drivers are up to date. I'm using windows 8.1. It's not up to date, but its mostly security update that is not installed. I don't understand why this should be an issue when MPC-HC is working fine with the same configuration and video file.

 

The problem started after I upgraded to a nvidia 1070. My previous gpu didn't have the powers to render all the frames per second for 4K. I have tried 2 different drivers for 1070 and made a clean reinstall of the gpu drivers

Are you using edge filters? That will have a later version of madVR.

Can you post a screenshot of the file details?

The screenshot is in my native language, which may make it difficult for you

If you go to the movie in the web app, scroll down and it will give you the details. Can you post that?

OK, so that looks like it would be alright. Let's look at your filter selection. Are you using edge filters, and have you changed any MadVR settings? From your earlier post, it looks like there may be a subtitle issue. MPC is going to use different filters, unless you've altered it to use LAV?

Hi

 

I'm using edge, but it doesn't make a difference if I'm running stable. I have heavily customized madvr, but I have tried with a standard madvr and I get the same result. I use the same customized settings in mpc with success. I might have to retry this experiment, because of new version of madVR and just to recheck my findings.

 

I'm uncertain if  I have modified lav but I have attached screenshot.

 

Personally I suspect madVR because of the stacktrace above. Also sometime the player-app fails when I pause the video, but again I can't replicate it reliable.

 

Thanks for all your help.

Those pictures are LAV, and they will have no affect in theater. LAV is controlled internally by theater.

I have change the configuration so the icon is shown when emby theater is playing. The screenshot is from another movie I played in theater. My current understanding is that even if I change anything in the screen in the screenshot it will not effect anything because emby theater will override the settings when calling lav.

You probably want to alter your MadVR settings

Post the question in the theater forum. I'm pretty sure there are, but with varying GPUs.
