For the record, I have had detailed plans for all this for years. But
since it is very related to strings, it requires AVWriter, and it
requires the abstraction and type description layer that I want to
introduce that starts with AVWriter. Therefore, it cannot go forward
unless FFmpeg has once more proper leadership able to greenlight it.

I wild recommend using the fftools as a staging area.
