[REQ] ISO extraction

Post by flash3d » 08 Aug 2016, 18:15

Hi,

I would like to script the extraction of ISO files after the completion of the download. Could somebody help me with that script?
Extraction can be done in "DestDir".

I am also looking for a feature to "unpack" ISO files like NZBGet is doing it for RAR files.
Any ideas how to do this?

Hi,

I've created a nzbget post proccess script.

You can download it here: https://github.com/aeilkema/iso_extract
or create it from the code below.

Please feel free to modify it, it works great for me (maybe the script could use a cleanup :x ).
It was my first python script ever, so maybe expect some weird code (which does not mean it doesn't work :lol: )

If you find a bug please report it 8-)

greetings

Joachim Aeilkema

EDIT: created version 1.1, now:
  • only extract if current category is in categorylist in options

  • option to select if iso without should be extracted.


Version 1.1:
  • Function: Added category check

  • Option: ExtractWithoutCat, extract if current category is empty (yes/no)

  • Option: OnlyForCategories, list of categories to extract (comma separated list)


Code: Select all
