How to decrypt encrypted smi files from hulu.com

chanc · #1 10-06-2012, 09:21 AM

While using hulu.sh, I can download http://www.hulu.com/watch/358372. And I can also get the encrypted subtitles in the form of smi file.But without decrpting it, the subtitles are a bunch of meaningless numbers and letters.
Any way to decrypt such files ?
If open the file in txt , it is like this :

Code:

If you have python, this should work

code.google.com/p/bluecop-xbmc-repo/source/browse/trunk/plugin.video.hulu/resources/lib/subtitles.py

otherwise I can try to port that into something else

Thanks, SVNPENN.You are always there to offer help. How generous!

But python is totally unfamiliar to me.

Could you please turn it into something that can be run in cygwin ?

Thank you very much.

I have installed python in my computer.
When I ran subtitles.py in cygwin, I got :

Code:

Administrator@pc ~
$ python -V
Python 2.7.3

Administrator@pc ~
$ cd c:/cygwin/usr/local/bin/

Administrator@pc /usr/local/bin
$ python subtitles.py
Traceback (most recent call last):
  File "subtitles.py", line 1, in <module>
    import xbmc
ImportError: No module named xbmc

Administrator@pc /usr/local/bin
$

The subtitles.py seems to be a part of a plugin of xbmc. I don't know how to make it work.
