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

John,

DirectShow has the capability to combine different transform filters in such a way, that many input formats can be converted to many other formats.
