how to use the encoder when i CreateComponent, it return AMF_NOT_SUPPORTED

[jamaik7]

i test the code in Win10

Environment:
Windows10 1809
Adapter: Radeon Pro S7150v AMD MxGPU
Driver: Adrenalin-Edition-17.12.2 (17.50.07)
i use the AMF-1.4.6

`
int _tmain(int argc, _TCHAR* argv[])
{
AMF_RESULT res = AMF_OK; // error checking can be added later
res = g_AMFFactory.Init();
if(res != AMF_OK)
{
wprintf(L"AMF Failed to initialize");
return 1;
}

::amf_increase_timer_precision();

amf::AMFTraceEnableWriter(AMF_TRACE_WRITER_CONSOLE, true);
amf::AMFTraceEnableWriter(AMF_TRACE_WRITER_DEBUG_OUTPUT, true);


// initialize AMF
amf::AMFContextPtr context;
amf::AMFComponentPtr encoder;
amf::AMFSurfacePtr surfaceIn;

// context
res = g_AMFFactory.GetFactory()->CreateContext(&context);
AMF_RETURN_IF_FAILED(res, L"CreateContext() failed");

if(memoryTypeIn == amf::AMF_MEMORY_DX9)
{
    res = context->InitDX9(NULL); // can be DX9 or DX9Ex device
    AMF_RETURN_IF_FAILED(res, L"InitDX9(NULL) failed");
}
if(memoryTypeIn == amf::AMF_MEMORY_DX11)
{
    res = context->InitDX11(NULL); // can be DX11 device
    AMF_RETURN_IF_FAILED(res, L"InitDX11(NULL) failed");
    PrepareFillDX11(context);

}
// component: encoder
res = g_AMFFactory.GetFactory()->CreateComponent(context, pCodec, &encoder);`

it return AMF_NOT_SUPPORTED and AMFComponentPtr encoder is NULL ptr
how can i run this simple

• Which codec do you try to create?
• What do you see in the debug output?
  You have almost two years old driver. Try the latest hotfix from amd.com.

@MikhailAMD
1.AMFVideoEncoderVCE_AVC
2.SimpleEncoder.cpp:AMF_RETURN_IF_FAILED(res, L"CreateContext() failed");fail AMF_NOT_SUPPORTED
3.Because i use it in the Virtualization https://www.amd.com/zh-hans/support/professional-graphics/firepro/firepro-s-series/firepro-s7150-x2 the page support my driver only the 17.12.2 so i have not try other version driver.

Driver for virtualized GPU doesn't support encoder. You would have to put the GPU in passthrough mode.

@MikhailAMD how can i get the gpu output ,because i find the dxgi can't screenshots in exclusive mode

[MikhailAMD]

Not sure I understand the question. Do you need to capture screen and have problems? If so, there are two APIs: DesktopDuplication API from Microsoft https://docs.microsoft.com/en-us/windows/win32/direct3ddxgi/desktop-dup-api. I would start with it. AMF has a sample how to use it. Check VideoCapture component. Also there is AMD DOPP API connected to OpenGL. Works only with Pro GPUs and drivers. https://github.com/GPUOpen-LibrariesAndSDKs/DOPP

@MikhailAMD such as game play in full screen mode ,dxgi only capture the black image. NVIDIA have a solution(NvFBC), it can capture image from GPU output buffer

[MikhailAMD]

Did you try on regular, not VM setup? You can use OBS studio and enable DD mode.

[jamaik7]

@MikhailAMD I will try it ，thanks for your help

[MikhailAMD]

BTW: for AMD the solution is DOPP

[jamaik7]

ok thanks

When will it be supported?

[MikhailAMD]

Realy sorry but I cannot comment on non-released features.

[AlanDaniels101]

Thanks Mikhail. This is critical for our use case. Seems like cloud gaming and Citrix-type products would use this too. Hopefully it comes through soon.

If you like you can send me a private info about your project. I will show it to the people involved. Email:
