Hi:
I'm almost there, actually everything works great, but I'm trying to understand how, when I set the Logitech Quick Cam PRO 3000 for I420 format, the framegrabber sink color format for eUYVY, everything works. My question is, how does it convert from YYYYYYYYYYYYYYYY....UUUU....VVVV....(I420-a 12 bit per pixel format) to UYVYUYVYUYVY.....(eUYVY-a 16 bit per pixel format). I know it does because I just do a memcpy into my overlay surface (line by line of course to take care of Stride) and everything works.
Thanks and Regards,
John Oehrle
