We agree, except on the last point.
All user-visible FFmpeg types should have a way for the user to input
them, self-contained and convenient with regard with the logic of the
type, and a function to print them in a way that can be parsed back.
Channels layouts do not have multiple options, they have
av_channel_layout_from_string(). Rationals are not entered with
-framerate_num 24000 -framerate_den 1001, they are entered as a ratio,
and so on. It should be systematic.
