A common preferred pixel format for webcams is YUY2. Mac has a great texture format which allows you so upload the texture as one image from which you can sample the Y,U,V components in a shader w/o any extra texture coordinate calculations for the U,V offsets. This can be done using GL_UNSIGNED_SHORT_8_8_APPLE on Mac. Though so far I haven’t found such an extension for Windows.
But because YUY2 is such a common format, I’m wondering fif someone knows an extension or maybe a standard solution to handle YUY2 on Windows?
