使用D3D11将NV12转成RGB

我显示使用硬解解码出视频，但是解码器只支持NV12的格式，需要转成RGB格式显示，并且这部分在GPU里面做，速度也会比较快，但是，碰到问题：D3D11 CORRUPTION:ID3D11DeviceContext::VideoProcessorBlt: Second parameter does not match device;

D3D11_TEXTURE2D_DESC dstDesc;
ZeroMemory(&dstDesc, sizeof(dstDesc));
dstDesc.Width = s->width;
dstDesc.Height = s->height;
dstDesc.MipLevels = 1;
dstDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
dstDesc.SampleDesc.Count = 1;
dstDesc.ArraySize = ctx->num_surfaces;
dstDesc.BindFlags = D3D11_BIND_RENDER_TARGET;
dstDesc.CPUAccessFlags = D3D11_CPU_ACCESS_READ | D3D11_CPU_ACCESS_WRITE;

ID3D11Texture2D *srcTextureNV12Fmt = texture;
ID3D11Texture2D *dstTextureRGBFmt;
