320-15AST DXVA Problems

2019-07-28, 7:46 AM

Hi!

I've been playing with Geforce NOW for 1 year, but about 2 months ago it immediately stopped working properly. The problem is that DXVA (DirectX Videa Acceleration) isn't working on my notebook. In my opinion, it has worked well until Geforce NOW stopped working. I have tried to reinstall my whole notebook, update BIOS and all of my drivers, but it's still now working. I runned DXVA Checker, and this program didn't see my dedicated graphics card, AMD Radeon 530. I think this may be the problem. 

Please, help me!

In theory both the integrated GPU and the discrete GPU should handle video de/encoding. Since the iGPU and the discrete GPU are from the same chip architecture, the iGPU can decode and encode videos just as reliable as the dedicated GPU so I can't see that as a problem. I read that GeForce Now doesn't like the AMD Microsoft drivers and that you should install the drivers directly off the AMD page. Maybe that helps.

I tried to uninstall the amd software and download it from the amd's webpage, but Geforce NOW still not working and DxDiag says that DXVA not supported. What's now?

Well, since when does dxdiag show information about DXVA? Certainly doesn't do that on my system, even though the Intel HD 4000 is DXVA-capable. AMD Stoney Ridge CPUs all are DXVA capable. I think that you messed up something in your system. Try running

sfc /scannow

Maybe that helps. Otherwise I think that some of your applications messed this feature up, because that is a standard feature.

Download the application DXVA Checker, that says what your device can decode. If it shows file formats, it is actually DXVA capable. Looks somethink like this.

DXVA Checker shows nothing and sfc /scannow says: Windows Resource Protection found corrupt files but was unable to fix some of them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.

It seems like some DirectX components on your system are damaged somehow because DXVA is a standard driver feature on basically every GPU nowadays, including your integrated GPU. You could run sfc /scannow multiple times and see if that works.

DISM.exe /Online /Cleanup-image /Restorehealth
Is also a command you could try, that also restores faulty files.

The only thing that I could come up with is reinstalling Windows through the system menu. DirectX is an integral part of Windows and if that doesn't work there is something seriously off.

https://download.microsoft.com/download/1/7/1/1718CCC4-6315-4D8E-9543-8E28A4E18C4C/dxwebsetup.exe

That is the DirectX Web Setup, you could try running that to install all the other DirectX files.

I reinstalled the windows already, but it wasn't solution. SFC now says that it hasn't found anything, and now my Adobe premier isn't working too because it isn't found any capable video card. Both my windows and AMD driver are the newest. I just don't know what's going on with my notebook.

I guess I also couldn't help you with this, this is really odd and I have never seen that happen before. Maybe the recommended drivers don't work 100% correct with Windows 10 1903, but I really have no idea. It is a hardware/driver feature that is being supported by basically every iGPU since like 2012. Maybe the iGPU is partially damaged?
