I found this information dug up from this and the x264-devel maling
list quite useful:

for -lavdopts debug=8 from
:http://lists.mplayerhq.hu/pipermail/mplayer-docs/2006-February/007261.html


> debug=8 prints the type of each macroblock in each frame.
> The primary types are:
> I	Intra 16x16
> i	Intra 4x4 or 8x8
> P	Intra PCM
> A	Intra with AC prediction
> >       Inter forward
> <       Inter backward
> X       Inter bidirectional
> S       Skip
> D	Direct
> d	Direct, no residual
> G       GMC
> g	GMC, no residual
>
> This may be followed by a modifier:
> (blank)	no partitions
> +	8x8 or smaller partitions
> |	8x16 partitions
> -	16x8 partitions
> =	Interlaced

> The current color scheme is designed like this:

 Is this documented anywhere else? Is the colorscheme mentioned above
for debug=0x4000 correct?
