- FourCCs: YUY2, UYVY
YUV 4:2:2 is a packed YUV format in which a pair of consecutive pixels is represented by 1 Y sample each but share a U sample and a V sample.
This type of data may be packaged in a container format with a a FourCC of YUY2 which indicates the following byte formatting:
Y0 U Y1 V
The first pixel is a a function of (Y0, U, V) and the second pixel is a function of (Y1, U, V). Alternately, the FourCC UYVY is used to indicate YUV 4:2:2 data with a byteswapped order:
U Y0 V Y1
