Here's a new patch with the above handled, I think this is the correct
method as that will extend easily to all other mpeg formats. It's currently
only implemented for h264, and the coef's are only output as the index given
by mpeg. This should extend to encoding too, but that's for another patch.

Might be possible, thou I've as of yet not seen any reference to these coefs
in rationals, so I'm not sure where to get ahold of that.
