FOURCC value for "Hap Q Alpha"? #36

Closed LukasBanana closed 7 years ago

Can anyone tell me the correct FOURCC value for Hap Q Alpha?

I'm only aware of these ones:

#define FOURCC_Hap1 MAKEFOURCC('H','a','p','1') // Hap
#define FOURCC_Hap5 MAKEFOURCC('H','a','p','5') // Hap Alpha
#define FOURCC_HapY MAKEFOURCC('H','a','p','Y') // Hap Q
/*                    ???                    */ // Hap Q Alpha

And by the way: Where does the letter "Q" come from within the "Hap Q" and "Hap Q Alpha" names? Hap Q has "YCoCg" color space for instance, so what does the "Q" mean in that context? The nomenclature seems a little confusing to me.

HapM - See the specification.

Q is for quality.
