Format configuration for NV12/NV21 with downscale ratio 2x. Positive biHeight implies top-down image (top line first) NV12. So I ran a Diagnostic Report on my system with Advance System Care and I got these errors. We can see that it's very easy to play a video file to VCam, and you can also play a video capture device, a video stream, an image file or any other video sources to VCam with DirectShow easily. In D3D9, I'm able to use UpdateSurface to transfer the NV12 video surface to a BGRX surface assigned to the D3DImage. The Y plane has one byte per pixel. I have a YUV:411 (aka NV12) frame data, how can I get OpenGL to recognize its format for glTexImage2D() rendering. New name is "Resizing NV12 image using Nearest Neighbor Interpolation and Bilinear interpolation algorithms".
