title: D3D texture to NVIDIA Media Foundation Encoder
body: <p>I want to encode a ARGB D3D11 texture by the NVIDIA H.264 Encoder MFT directly.But i found this MFT's input type must YUV format like NV12. So i have to map texture to memory then transform to NV12.Is there any way can avoid memory copying?Or how can i transform a ARGB texture to NV12 texture no memory copy?</p>
