MEDIASUBTYPE_YU10 – 10bit Y + 10bit Cb/Cr – 20bit YCbCr
4:2:2
‘ x’ means ‘don’t care bit’.
Its compression (FOURCC code) is ‘YU10’ and GUID is
30315559-0000-0010-8000-00AA00389B71.
Notes for the MEDIASUBTYPE_YU10 format:
Total bytes of one scan line need to be aligned to multiple of
16. If the requirement is not met, HDV62 appends dummy
bytes to the end of each line. For example,
if width = 800 pixels, each line = 2144 bytes (11 dummy bytes
appended);
if width = 640 pixles, each line = 1712 bytes (5 dummy bytes
appended);
if width = 720 pixles, each line = 1920 bytes (0 dummy bytes
appended).
The formula is: total bytes of each line = ((width * 16 / 6) + 15)
& ~15 with all integer calculation.
The formula to convert YCbCr to RGB is as following:
R = Y + 1.371(Cr-128)
G = Y – 0.698(Cr-128) – 0.336(Cb-128)
B = Y + 1.732(Cb-128)
