[FFmpeg-user] Dealing with an intermittent rtsp source

[Enrico Purisima]

Hello Ben,

I encounter a similar problem regularly and have written a few scripts to
monitor the progress of the ffmpeg and to kill and restart the ffmpeg
process if it's hung. There are three files in the zipfile attachment:
ffmpeg.sh, monitor_stream.sh and stop_ffmpeg.sh. ffmpeg.sh runs your ffmpeg
command and starts up the monitoring script. You will need to edit the
files to replace your_login_user and path_to_script with the appropriate
values. (These were extracted from a larger script I have, so I hope I
haven't introduced any fatal typos.) I run these on Ubuntu but it should
work on other Linux distros as well.

Hope this helps.

Enrico
