I try to get a handle of this d3d11texture : getsharedhandle, open the handle by the d3d11on12 device : opensharedresource ,and then map the d3d11texture to d3d12
: UnwrapUnderlyingResource.But i can only get the Y data.

2022-04-20T03:35:31.733+00:00 I get the NV12 from ffmpeg d3d11va decoder.
D3D11_TEXTURE2D_DESC texture_desc = {0}; texture_desc.Width = 640; texture_desc.Height = 480; texture_desc.MipLevels = 1; texture_desc.Format = DXGI_FORMAT_NV12; texture_desc.SampleDesc.Count = 1; texture_desc.ArraySize = 1; texture_desc.Usage = D3D11_USAGE_DEFAULT; texture_desc.MiscFlags = D3D11_RESOURCE_MISC_SHARED; Microsoft::WRL::ComPtr<ID3D11Texture2D> shared_texture_for_ffmpeg_device{nullptr}; ffmpeg_device->CreateTexture2D(&texture_desc, NULL, &shared_texture_for_ffmpeg_device); ffmpeg_device_context->CopySubresourceRegion(shared_texture_for_ffmpeg_device.Get(), 0, 0, 0, 0, (ID3D11Texture2D*)ffmpeg_avframe->data[0], (int)ffmpeg_avframe->data[1], NULL); ffmpeg_device_context->Flush(); Microsoft::WRL::ComPtr<IDXGIResource> dxgi_resource{nullptr}; shared_texture_for_ffmpeg_device.As(&dxgi_resource); HANDLE shared_handle = NULL; dxgi_resource->GetSharedHandle(&shared_handle); dxgi_resource->Release(); Micsoft::WRL::ComPtr<ID3D11Device> my_d3d11_device{nullptr}; my_d3d11on12_device.As(&my_d3d11_device); Microsoft::WRL::ComPtr<ID3D11Texture2D> temp_texture_for_my_device {nullptr}; my_d3d11_device->OpenSharedResource(shared_handle, __uuidof(ID3D11Texture2D), (void**)temp_texture_for_my_device .GetAddressOf()); my_d3d11on12_device->UnwrapUnderlyingResource(temp_texture_for_my_device .Get(), my_d3d12_command_queue.Get(), IID_PPV_ARGS(&my_d3d12_resource)); -

2022-04-20T03:35:44.553+00:00 If i need read back
ID3D11Texture2D* readback_buffer; ID3D11Texture2D_DESC readback_desc = { 0 }; readback_desc.Width = 640; readback_desc.Height = 480; readback_desc.MipLevels = 1; readback_desc.Format = DXGI_FORMAT_NV12; readback_desc.SampleDesc.Count = 1; readback_desc.ArraySize = 1; readback_desc.Usage = D3D11_USAGE_STAGING; readback_desc.CPUAccessFlags = D3D11CPU_ACCESS_READ | D3D11CPU_ACCESS_WRITE; my_d3d11_device->CreateTexture2D(&readback_desc, NULL, &readback_buffer); my_d3d11_contex->CopyResource(read_back, temp_texture_for_my_device.Get() ); my_d3d11_contex->Flush(); D3D11_MAPPED_SUBRESOURCE mapped; my_d3d11_contex->Map(readback_buffer, 0, D3D11_MAP_READ, 0, &mapped); -

2022-04-20T07:53:55.293+00:00 Try this
my_d3d11on12_device->UnwrapUnderlyingResource(temp_texture_for_my_device.Get(), my_d3d12_command_queue.Get(), __uuidof(ID3D12Resource),&my_d3d12_resource);
I think the process you copied conforms to the official instructions. Could you debug the change oftemp_texture_for_my_device -

2022-04-20T08:08:43.563+00:00 Thanks for your anwser,but i get a same result.
When i maptemp_texture_for_my_deviceto CPU, i can only get the Y datas,but when i mapshared_texture_for_ffmpeg_deviceto CPU, it's normal.
I'm confused,it's a same resource with different pointer. -

2022-04-20T08:14:09.61+00:00 or Try this, Not use
AS,IDXGIResource* dxgi_resource(NULL); shared_texture_for_ffmpeg_device->QueryInterface(__uuidof(IDXGIResource), (void**)& dxgi_resource); HANDLE shared_handle = NULL; dxgi_resource->GetSharedHandle(&shared_handle); dxgi_resource->Release(); -

2022-04-20T09:03:07.883+00:00 Of course.
Create d3d11on12 device:int d3d11_device_flags = D3D11_CREATE_DEVICE_VIDEO_SUPPORT; Micsoft::WRL::ComPtr<ID3D11Device> d3d11_device; Micsoft::WRL::ComPtr<ID3D11DeviceContext> d3d11_device_context; D3D11On12CreateDevice(my_d3d12_device.Get(), d3d11_device_flags, nullptr, 0, reinerpret_cast<IUnKnow**>(my_d3d12_commadn_queue.GetAddressOf()), 1, 0, &d3d11_device, &d3d11_device_context, nullptr); Micsoft::WRL::ComPtr<ID3D11DeviceContext4> my_d3d11_context; Micsoft::WRL::ComPtr<ID3D11On12Device2> my_d3d11on12_device; d3d11_device.As(&my_d3d11on12_device); d3d11_device_context.As(&my_d3d11_context);Create d3d12 device:
D3D12CreateDevice(nullptr, D3D_FEATURE_LEVEL_11_0, IID_PPV_ARGS(&my_d3d12_device)); D3D12_COMMAND_QUEUE_DESC queue_desc{}; queue_desc.Type = D3D12_COMMAND_LIST_TYPE_DIRECT; queue_desc.Flags = D3D12_COMMAND_QUEUE_FLAG_NONE; my_d3d12_device->CreateCommandQueue(&queue_desc, IID_PPV_ARGS(&my_d3d12_queue));If you need anything else, I can continue to provide.

2022-04-26T09:34:52.917+00:00 Thanks for your help,my problem is solved.Maybe d3d think there is only one subresource in
temp_texture_for_my_device,so when i copytemp_texture_for_my_devicetotexture_for_my_deviceviaCopyResource,only the luma data is replicated. -

2022-04-26T09:48:48.783+00:00 Glad that your problem has been solved. I didn't find
CopyResourcein your code. I tried to reproduce your situation these days but failed. If you have any other questions, please feel free to ask them.
