Microsoft's Enhanced Video Renderer not working with Intel UHD Graphics 770

[RamashankarAgrahari]

Hi,

I have a pc whose configurations are:

• CPU: 12th Gen Intel® Core™ i5-12500T
• Graphics: Intel® UHD Graphics 770 (driver 30.0.101.1371)
• OS: Windows 10 Enterprise LTSC Version 1809 (Build 17763.4131)
• SSU report is also attached for other details.

In this environment, when I use some of our product's applications, which uses Microsoft's EVR(Enhance Video Renderer) for video rendering, then they are not working properly. I have a doubt on intel graphics driver because if I rollback this driver and move to Microsoft basic display adapter then these apps starts working fine.

This issue can also be simulated by using Microsoft's GraphEdit or GraphStudio tool.

Steps: Insert a 'file source' filter and EVR filter. Render the file source. It does not get connected with EVR, even if I force to connect manually.

But If I rollback to Microsoft Basic Display Driver then EVR is able to connect and work properly  

I am suspecting that raw video format required for rendering is not supported by EVR due to intel graphics driver. I also upgraded the intel Graphics driver manually with latest version (gfx_win_101.4311) but issue still persist.

Note: I have another pc with same OS (Windows 10 Enterprise LTSC Version 1809 (Build 17763.4131)) and having CPU: Intel® Core™ i3-8100 CPU @ 3.60 GHz, Graphics: Intel® UHD Graphics 630 (driver 26.20.100.7158). EVR is working properly on that pc. So it also eliminates any doubt over windows LTSC OS version.

~ Thanks.
