I'm perfectly calm and wasn't perceiving any blame. I'm just trying to
point out what I have been thinking. See more below.

I think it would be better to tackle the whole problem rather than
spending time working on temporary fixes that affect the output of
other codecs in FFmpeg. 'If you're going to do something, do it well'
and all that. :) It would be quite a large job, but I think it would
be worthwhile in the long run. If we get some discussion going and can
pin down what exactly is a good approach to the problem then actually
coding the solution should probably only eat a few hours of someone's
time.
