TVHeadend Python PostProcessing script
Author: ckarrie <>
Python PostProcessing script that deletes all duplicate recordings according to their
description and filesize. The script keeps the recording with the largest filesize.
1) put this python file somewhere (i.e. /media/daten/tvheadend/
2) Add this line to TVHeadend > Configuration > Recording > [your recording settings] > Post-processor command
replace <path/to/this/file/> according to Point 1)
/usr/bin/python2.7 /media/daten/tvheadend/ "%f" "%d"
3) Record something with this recording settings
