what maintaince does it need ?
i mean i know the code is ugly but what _needs_ to be changed?

libpostproc implements part of ISO/IEC 14496-2
(that is the spec for an MPEG-4 ASP decoder)

its content could be moved in libavfilter and or the mpeg4 decoder
(there are arguments to be made for either)
but it doesnt belong in a lib external to FFmpeg.
(and in the process some bits probably can be droped as they
 no longer serve a purpose compared to other filters)

I have too many other things to work on to do a big refactoring of it
but if there are small bugs in it or questions about it i can look into them

thx

Asymptotically faster algorithms should always be preferred if you have
