OnAcceleratedPaint with OSR

[davide-aldegheri]

Greetings, I wanted to know I can use the hardware acceleration to render the shared texture coming from OnAcceleratedPaint to a texture buffer so that I can use it in an offscreen environment.
I've tried following the example on cefsharp/CefSharp.OnAcceleratedPaint.Example but I'm getting an exception when creating the device, most likely due to the fact that I have no experience with D3D11 apis, on the line _output = _swapChain.ContainingOutput; which gives me

SharpDX.SharpDXException: HRESULT: [0x887A0004], Module: [SharpDX.DXGI], ApiCode: [DXGI_ERROR_UNSUPPORTED/Unsupported], Message: The specified device interface or feature level is not supported on this system.

   at SharpDX.Result.CheckError()
   at SharpDX.DXGI.SwapChain.GetContainingOutput(Output& outputOut)
   at SharpDX.DXGI.SwapChain.get_ContainingOutput()

The sample from the aforementioned sample works so I don't think it's anything related to my hardware. My guess is that is something like the IntPtr handle used to create the swap chain.

Can someone put me on the right track with this?

I'm on Windows 10, using .NET Core 9

Thanks

The example was contributed by a community member. Unfortunately I don't know much about D3D. I've updated it to the latest version of CEF and appears to be working ok.

Looks like you've asked at https://stackoverflow.com/questions/79524053/usage-of-onacceleratedpaint-in-osr

Hopefully someone there will be able to help you out.

Thank you @amaitland, no worries however, the next day I've asked that question on SO I was able to obtain a result of the texture shared by CEF in the OnAcceleratedPaint info. I had to dig deep in various info on D3D, which are not that well documented, but I can now share it with other devices, if you want, I could make a pr with a minimal example that could save a screenshot on disk with the obtained result

Nice one!
