 Summary of the bug:
 If there was any data flow, then ffmpeg process is interrupted well at
 first time. If there was none, it needs another signal.

 I recall that i have once reported exactly same bug, and it was resolved.

 How to reproduce:
 Run the following command when there is no data flow at given UDP address,
 and try to interrupt it via Ctrl+C or kill command.
