The current algorithm and all the heuristics present in libavfilter
should be consolidated and made optional. We have too many workarounds
that might solve something breaking something else (e.g. the mpegts
produced by some old vlc fed by an axis camera are wrongly workarounded
as I recently discovered). It needs a non small effort and possibly lots
of people working together. You seem interested on the topic, would you
help us sorting it out completely?
