It has greatly progressed last Thursday. At this time, I need to figure out
why it mangles the audio in 32-bits while it works perfectly in 16-bits.
Then I will have to stress-test it, clean up and write the doc. This is
currently my highest-priority task on the ffmpeg queue.

I see the it the other way around: filters should be the default way to do
anything, as they have a generic interface and can be ordered with regard to
each other.

(A non-audio example for the part on the ordering: depending on how you
state your arithmetic and what you want to do exactly, you may want to scale
and then crop or on the contrary crop and then scale: scaling and cropping
need to be filters you can organize as you need.)

OTOH, the filtering system has currently a limitation that makes it slightly
awkward to use it for mapping: filters can have only have a fixed number of
inputs and outputs, which means that if you need to merge three streams, you
have to use two merge filters.

I wonder if that limitation could be lifted.
