I'm testing 2023-1206-2 and about half the time, Control-C won't work and I have to look up the PID and kill the process. Could I listen to a q keypress or offer another quick while to halt capture.

btw, with dvrescue ... -m file -m - | mpv -. If I close mpv, then the SIGPIPE signal does consistently stop dvrescue, with about a one second delay btw closing mpv and dvrescue stopping.

With --in-control you can use 'q' to quit ,normally.

Does control-c works without --control or with a firewire deck? (I try to guess if a linked library overwrite my signal handler)
