ffmpeg | branch: master | Alexandre Colucci <alexandre at elgato.com> | Fri Mar 25 17:31:28 2011 +0100| [d980d7b1295290cedd978ef53118513838aa1484] | committer: Anton Khirnov

pgssubdec: fix incorrect colors.

On Blu-ray colors are stored in the order YCrCb (and not YCbCr) as mentioned in the specifications:
see System Description Blu-ray Disc Read-Only Format, 9.14.4.2.2.1 Palette Definition Segment

When decoding a Blu-ray subtitle, the colors were incorrectly set.
