Downloading/decrypting ts files with AES-128 from m3u8

[thecontroller]

Hi,

I've spent many hours looking through previous threads with similar problems, but I can't seem to find a way to do this.

There isn't one particular video I want to download, but I'll use this one as an example: http://www.9jumpin.com.au/show/brita...-3/audition-3/

The m3u8 file is here: https://secure.brightcove.com/servic...=4270762636001

An example of one of the key files is here: https://secure.brightcove.com/servic...041b14303016e7

When I try to use the ffmpeg code, I get the message "Unable to open key file".

I'd be very grateful if anyone could offer a solution! Thanks!
