Having stair step problem on image bounderies and texture filtering(bilinear, trilinear or anisotropic) is having no effect on image quality.

Hi,
I have imported your TextureUWP project for plugin build. I am streaming H264 encoded frames(webcam via Gstreamer) and rendering it on the cube(Hololens). I am having stair step issue on the edges of object in image frame. I have tried different texture sampling techniques but these have no(zero) effect on image quality. I have added below code snippet in TextureUWP.cpp file:

void CreateSampler()
{ //Called at intialization
ZeroMemory(&samplerDesc, sizeof(D3D11_SAMPLER_DESC));
D3D11_TEXTURE_ADDRESS_MODE addressMode = D3D11_TEXTURE_ADDRESS_CLAMP
samplerDesc.AddressU = addressMode;
samplerDesc.AddressV = addressMode;
samplerDesc.AddressW = addressMode;
samplerDesc.ComparisonFunc = D3D11_COMPARISON_FUNC::D3D11_COMPARISON_NEVER;
samplerDesc.Filter = D3D11_FILTER::D3D11_FILTER_MIN_MAG_LINEAR_MIP_POINT;//D3D11_FILTER_ANISOTROPIC;
samplerDesc.MaxAnisotropy = 16;
samplerDesc.MaxLOD = FLT_MAX;
samplerDesc.MinLOD = FLT_MIN;
samplerDesc.MipLODBias = 0;
}

Here I'm creating the sampler.
void UpdateUnityTexture(void* textureHandle, int rowPitch, void* dataPtr)
{
ID3D11Texture2D* d3dtex = (ID3D11Texture2D*)textureHandle;
assert(d3dtex);

ID3D11DeviceContext* ctx = NULL;
m_Device->GetImmediateContext(&ctx);
//New inserted lines
ID3D11SamplerState* sampler = NULL;
m_Device->CreateSamplerState(&samplerDesc, &sampler);
ctx->PSSetSamplers(0, 1, &sampler);
//
ctx->UpdateSubresource(d3dtex, 0, NULL, dataPtr, rowPitch, 0);
ctx->Release();
}

I have not used directX before. Am I doing it right? Please help.

Thanks
