Shutdown gracefully on SIGHUP

[hholst80]

There are additional signals that should be catched by the application and shutdown the stream gracefully. I managed to get this error again by spawning wl-screenrec in the background and then killing the terminal. I think this should signal, at least on Linux, a SIGHUP to the application.

# mpv screenrecord.mp4

for sig in signals:
    signal.signal(sig, sighand)


time.sleep(3600)
