I wonder, should we expect FFmpeg to already be referenced by

The use case of "download video and watch it on another machine
never watch it)" seems somewhat esoteric.
I don't see why my use case should be sidelined as ‘esoteric’.
However, in my recent experience, youtube usually provides the
freedom-respecting formats only as separate audio and video
which must be recombined by youtube-dl, and in that case the
command line tool seems to be required.
This is a good argument. If including ffmpeg by default makes it
easier to request & mux freeër formats, let's do that.
I see two possible approaches: ffmpeg could be added to
propagated-inputs, or it could be instead be added to 'inputs',
could substitute hardcoded paths to 'ffmpeg' in the built
I generally tend to favor the latter approach, but there are
arguments for each approach and I don't feel strongly about it.
Which advantages does the former have? I wasn't aware of any.
