Revision as of 15:44, 16 October 2014
Anyone know the correct way to edit a skiplist in Python?
- Done. wagnerrp
It's stopped working recently
I can't figure out why but silence.cpp seems to be ignoring SIGALRM and so it never stops. If I kill the tail manually (like silence.ccp is supposed to in the alarm handler) it finishes properly. If I send a SIGALRM to silence.cpp nothing happens. I'm on Debian Wheezy and it was working until a few weeks ago so it is probably a kernel or security update. Has anyone else seen this behaviour?
Fixed in silence.cpp v4.2 - I don't know what has changed but the process has SIGALRM blocked when it starts so this change simply unblocks it and all is good in the world again.
A suggestion to improve the visibility of the running job in the Mythweb status page.
I would like to propose a small change to your code to include the following lines at line 178 of the silence.py script.
#Add this line to show the status in green in the Mythweb status page job.update({'status': 4, 'comment': 'Running.'})
With this line added the status of the job shown in Mythweb status page shows running in green whilst the job is running, this is only a small cosmetic change but it helps to identify a running job in a long list of finished and queued jobs.
For some recordings the detection does not really start and never ends => jobqueue is blocked!
Here is a snipped from the mythcommflag.log:

Afer a few minutes of blocking the jobque I killed the lowest childprocess and the log gets a finished line:
Oct 16 17:27:05 obelix silence.py[10378]: mythcommflag: Detected 0 adverts.
Here is the commandline for the job:
/usr/local/bin/silence.py %JOBID% --chanid %CHANID% --starttime %STARTTIME% --loglevel debug --nodblog --syslog local7 --presetfile ~/.mythtv/silence.preset
