Comment (by withmorten):
Hi clone206,
I ran into a similar problem this week when I wanted to cut off one second
of silence at the end of some files which I had added earlier (with
ffmpeg).
It wasn't too hard to implement and can probably be improved on sanity
check-wise, but it works for my purposes and can probably be used as a
good starting point for properly implementing this by somebody who knows
how ffmpeg is supposed to work:
https://gist.github.com/withmorten/ea585798076fa020b757437f23aca768
Diffed against ffmpeg 3.4.2.
It only works as input option (duration seemed to be unknown in
open_output_file), so you'll have to use it like:
ffmpeg -toeof -00:00:00.9 -i input.flac output.flac
It basically makes the input file shorter by whatever amount you tell it.
Not entirely sure why this would be impossible to implement ...?
