I am just focused on getting wide gamut encoded "right" at this point,
but the method HDMI uses to signal color boundaries might be a useful
addition in an SEI message (an optional/informative element in the
H.264 bitstream). H.264 has specific VUI (Video Useability
Information) parameters that are pitched to the Display Process so it
can implement the correct "render intent" e.g. wide gamut. Only thing
lacking is a method to signal "which wide?".
That is a major improvement over MPEG-2, which was designed when the
world had one choice (Rec 601), so the bitstream didn't have to deal
with these options.
