It doesn't do DRC so if I want to use my big old stereo speakers (my TV
speakers are crap) to listen to a recorded film it would vary between
being too quiet and too loud.
As I guess you know the default for 5.1 should be full drc applied and
mixdown to 2.0 makes it even more essential as (I believe) the act of
mixing down increases dynamic range.

It's the (unparsed by ffmpeg) ancillary data aspect not the specific codec.

Yes I know, but right next to it is about aac in fact it was searching
for aac stuff that found me that doc.
