Comment (by juannm):

 Replying to [comment:2 Balling]:
 > In that case triple Ctrl-C or maybe Ctrl + \ (SIGQUIT) should work, no?

 It does; at least on the manual test, the second Ctrl-C kills the FFmpeg
 process. But I see doing that a bit (a lot) like sweeping the underlying
 problem under a carpet... a big difference between letting FFmpeg know it
 should close, so it has time to adequately flush the output file, write
 the ending metadata (e.g. MP4 moov), etc; and simply killing it, which
 could render an unreadable output file.

 Also note the commands I provided are a simplified, minimal, reproducible
 example, not the actual use case. In reality there is a Node.js process in
 control of FFmpeg, among other things; it sends SIGINT to external
 processes, expecting them to exit and doing some additional cleanup on the
 process' exit events. But the event never arrives from the FFmpeg process,
 because it got itself into a soft-lock, and that's probably a bug caused
 by some internal control loop not acting as intended.
