Re: Adobe HDS Downloader

You are right it doesn't work.

Code:

HDS Link Detector works as expected and detects proper url with all required parameters.

Downloading 227322688/227322688 fragments

There was a little bit of security trick involved. script wasn't using the auth parameter with bootstrap requests and server was sending wrong bootstrap info in that case. i have fixed that in my repo. update your script either manually or

Code:

php AdobeHDS.php --update

Re: Adobe HDS Downloader

Hi

Is it possible to take this stream via X-Forwarded-For. It works for me only with "--proxy --fproxy", but the proxies are too slow.

http://live.stream.vrt.be/vrt_sporza...p/manifest.f4m

The stream is not always online.

Thanks in advance

Re: Adobe HDS Downloader

Hi KSV, your HDS link dectetor working perfect for http://www.cielotv.it/cielolive.html but the stream not start, i past batch process:

I am just posting it publicly. this info is based on actual reversing i tried few months ago. global key is different for each session. SessionID and KeyUrl are not of much relevance because they are only used to retrieve GlobalKey. mysterious salt block in each packet header can be broken into 4 different blocks. first was always 01 and third block was always all zeros.

Code:

SessionID: 010075cd3e8441c5f40f4427ae4f93e8b2b00a1b6740eda2fd0049958d1532318bd1423ec94a2c3f4074ede220dd615b9d588f6ad1ef

Encryption scheme used is AES-128-CBC. i couldn't figure out the KDF (key derivation function) used to derive individual packet decryption key from global key using the salt block as shown above. KDF function is executed inside Alchemy VM (a method used to execute c code from ActionScript VM) which makes it very hard to reverse engineer from disassembled code.
==========

KSV, what about FlashAccess DRM? Do you have an idea on a how protection scheme works, and to break it?

Thanks

Re: Adobe HDS Downloader

This message appears at the end. Waiting eagerly for the updates, it seems that the time to break encryption is near! Good job, KSV!

This stream is encrypted with Akamai DRM. Decryption of such streams isn't currently possible with this script.

You need to be little quick while using the command provided by add-on. for some websites manifest url is only valid for few seconds.

No, but FlashAccess uses even better methods to secure it's communication with Authentication Server unlike Akamai which sends global key in plain text.

Don't get your hopes too high. he has actually quoted a very old post.

Here is a link to an HLS protected stream played under Android: http://vod-and.llnw.cdn.m6web.fr/phl..._600k.mp4.m3u8 I know HLS != HDS but you may find some answers here...

Re: Adobe HDS Downloader

I'm in waaaay over my head here. Most of what I've read in this thread and on the AdobeHDS github wiki might as well be messages from aliens, since I'm comprehending all of this at about the same level.

I started a thread here, and was directed to AdobeHDS as a possible solution. But like I said, this stuff isn't making any sense to me. So let me talk this out. These are the steps I'll need to perform, correct me if I'm wrong (I'll be wrong... especially since I don't even know where the php code goes).

1. copy the code at github into a file called AdobeHDS.php (??)
2. install php 5
3. install the Firefox addon
4. run php from command prompt
5. navigate to video page
6. copy the pop-up url and paste it into the command prompt window
7. download begins
8. ???
9. PROFIT

Is this right? It can't be. There has to be something missing (probably lots of somethings) since there was more stuff on the wiki page that I don't understand, along with the fact that I don't know where the php code goes. Do I put it in the php folder?? Do I paste it into the command prompt? Does php run on any Windows OS without any additional requirements? WTF?? I'm so confused.

Sorry for being a total moron. Any clarification would be appreciated.

Re: Adobe HDS Downloader

please
it is possible to download fragments from rutube.ru?

like this one
