 Posted: Sat Dec 23, 2006 12:45 pm Post subject: on-connect scripts |
 |
|
hello
i use the following <on-connect> and <on-disconnect> scripts to start a transcoding on a freebsd server.
i write a pid file for the streamtranscoder and then i kill the process when it stops.
but it just works when i start from the shell (as well with the icecast user), when i let it start automaticly from icecast it creates the file but doesn't write into it.
| Code: |
<on-connect>/usr/local/share/icecast/bin/streamtranscoder1start.sh</on-connect>
<on-disconnect>/usr/local/share/icecast/bin/streamtranscoder1stop.sh</on-disconnect>
|
streamtranscoder1start.sh
| Code: |
#!/bin/sh
cd /usr/local/streamtranscoder/
/usr/local/bin/streamTranscoder -c /usr/local/streamtranscoder/streamtranscoder1.conf 1>/dev/null &
sleep 10
ps -aux |grep -v grep | grep /usr/local/streamtranscoder/streamtranscoder1.conf | awk '{print $2}' > /usr/local/streamtranscoder/pid/streamtranscoder1.pid
|
i tried to stop it directly without the pid file but it doesn't work neither
streamtranscoder1stop.sh
| Code: |
#!/bin/sh
kill -9 `ps -aux |grep -v grep | grep /usr/local/streamtranscoder/streamtranscoder1.conf | awk '{print $2}'`
kill -9 `cat /usr/local/streamtranscoder/pid/streamtranscoder1.pid`
rm /usr/local/streamtranscoder/pid/streamtranscoder1.pid
|
i think it is related to the way icecast starts the scritps, has anyone a idea what i do wrong or how to stop a process?
i could do some ugly things like writing into a file 0 or 1 read it out with a cronjob and then run the scripts.... but... i whould prefere to do this directly.
thx

The scripts are run when the stream has started or is shutting down so if the idea is that ST transcodes this stream to another mountpoint then the mechanism should be fine.
In the start script you don't need the ps/grep/awk etc to get the pid. You should be ok with just
echo $! > st.pid
Without knowing what it's actually doing then it's hard to say what the solution to the problem is. You may need from exho statements in the scripts to see how far it's getting.

thank you very much... that did it!!
here is the working startscript:
streamtranscoder1start.sh
| Code: |
#!/bin/sh
cd /usr/local/streamtranscoder/
/usr/local/bin/streamTranscoder -c /usr/local/streamtranscoder/streamtranscoder1.conf 1>/dev/null &
sleep 10
echo $! > /usr/local/streamtranscoder/pid/streamtranscoder1.pid
|
yes i do a transcoding from a livestream to a other quality, both streams (lofi + hifi) have a (seperate) fallback.
the problem was when i disconnect the livestream it will start the fallback then it transcodes the fallback stream, which is unnessecary for me and each time i reconnect to the mountpoint with a source it starts a new transcode process.
somehow i don't know why it didn't work with ps/grep/awk... but with echo$! it works.
thank you

|
|
hello
unfortunatly it does not always (just sometimes) write the pid into the file.
i need to stop the transcoding after the stream stopped so is there a other way to get the pid file on my freebsd for the streamtranscoder?
or does anyone have a other idea?
thx

You have to track this further, is it a question of ST dying before the file is written or a problem of actually writing the file?

well... now with freebsd 6.2 it works well.
i think it was a problem with the freebsd 4.* we had.
