The code you linked to looks to be nearly identical to this code here:
http://www.google.com/codesearch?hl=en&q=show:spitw_BsS18:XktR4Rb56GI:ZMtqWWQie4Y&sa=N&ct=rd&cs_p=http://libmpeg2.sourceforge.net/files/mpeg2dec-0.1.7.tar.gz&cs_f=mpeg2dec-0.1.7/libvo/yuv2rgb.c

It's from mpeg2dec-0.1.7 and claims copyright 1999-2000 Aaron Holtzman.  Of
course that doesn't necessarily mean Aaron Holtzman wrote it.  I've found
my code with someone else's copyright on it when they didn't write a single
line.  But this does appear to be the oldest version of the code I could
find, which is used all over the place.  I haven't found a version of
mpeg2dec older than 0.1.7 to see just how "new" the "new yuv2rgb code"
mentioned in the changelog for 0.1.7 really is.  Sometimes people think
changing a variable name makes something new.
