 ffmpeg doesn't reconnect when streaming to a remote server (e.g. rtmp://,
 tcp://) if the connection is lost.

 When running e.g.

 {{{
 $ ffmpeg -i ... -f flv rtmp://...
 }}}

 if the connection drops for some reason (e.g. `ifdown eth0`, network cable
 unplugged), ffmpeg doesn't reestablish the session when the connection
 becomes available again. In fact nothing happens, the process just hangs.

 `-loglevel debug` doesn't report anything, the `RTMP_SendPacket` just
 stops.

 This seems to have been discussed before:
 http://ffmpeg.org/pipermail/ffmpeg-user/2012-October/010137.html

 A pair of options like `-reconnect` and `-disconnect_exit` would make
 sense for TCP-based protocols?
