Re: restarting ffmpeg process

[Anthony Griffiths]

I wrote a script called stream-start.sh that follows your instructions but even though ffmpeg starts fine it does not create a pid file. I created this:

long-ffmpeg-command &

pid=$!

echo $pid > /var/run/stream.pid

but this didn't work and and after trawling google and trying a few variations the script still does not create a pid file.

in monitrc I have:

check process stream with pidfile /var/run/stream.pid

       start = "/usr/bin /root/start-stream.sh"

and monit starts without any complaints

but the monit log shows:

error    : monit: Error reading pid from file '/var/run/stream.pid'

error    : 'stream' process is not running

error    : monit: Start or stop method not defined -- process stream

thanks for any further advice.

I've tried but no success so far. I found this page http://mmonit.com/wiki/Monit/FAQ but I can't get the the wrapper script there adapted to my needs. (I don't know what JAVA_HOME and CLASSPATH=ajarfile.jar.is.) I start ffmpeg with a single (long) command in the console and either put a '&' on the end to background it or run it in a screen and then detach. This is how the process runs, it's not done by /etc/init.d/blah-de-blah. Can the monit wrapper script still work with this?

Any reason what ever script/program you have starting ffmpeg can't make
a pid file?
