Probably the key part?
Code:

Re: About capturing AES-128 encrypted stream


 
it is URLSnooper
this is all I can provide because it is an android app which is limited in hk and need to login
or any other info that I can provide?

Re: About capturing AES-128 encrypted stream


 
I don't know how to help without access to the stream and in this case is impossible, sorry. I have found another thread with the same URI
http://stream-recorder.com/forum/cap...st-t20654.html

But on my side, for the video on the #3 post, i don't see any encrypted content for the "chunks.m3u8"
Code:
EXTM3U
#EXT-X-VERSION:3
#EXT-X-ALLOW-CACHE:NO
#EXT-X-TARGETDURATION:5
#EXT-X-MEDIA-SEQUENCE:19713
#EXTINF:2.002,
l_20_59146203_19713.ts?nimblesessionid=etc.
Maybe is changed, i don't know.

Thanks for your quick reply
I double check the link, I think they are time-bounded
the following is a new link
it is a m3u8 containing the video part
don't know if it can help

or another method for me to extract useful info from the app?
it has android and ios version
Code:
