Do all webcams use YUY2?

I've noticed that raw data from my webcam comes in the from of YUY2. Actually, this "raw data" is the input for an AVICAP callback, and I suppose that this is the actual data from the webcam.

Anyway, do all the webcams use YUY2 format, or should I expect different formats as well?

+1 A:

YUY2/YUYV are probably most common. I've also seen web cams that used MJPEG, but are less common. Covering both of those will deal with a majority of non-network (Java or otherwise) style web cams.

Thanks. Would you happen to know the value of bmiHeader.biCompression for YUYV (too lazy to google it)?* "non-network (Java or otherwise) style web cams." what do you mean by that?

Some cams use proprietary interfaces with Java or IP based stuff. These are typically network web cams, rather than local USB cams.Not sure on the first. It would be a constant I would set and forget. :)
