[mythtv-users] silence detection blocks jobqueue [ mythcommflag; silence.py ]

[Stefan Pappalardo]

For some recordings the silence 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


I'm using mythbuntu 14.04 with mythtv 0.27 and the latest silence.py (from http://www.mythtv.org/wiki/Commercial_detection_with_silences)

Has anyone an idea how to solve the problem?
thx
