Well it seems that iPlayer Ondemand videos are not using adaptive streaming. So you must use rtmpdump to donwload those files. :(
But no worries here's how-to example:

If that seems too complicated use RTMPExploreX to download.

I'm guessing AdobeHDS.php is not in C:\Documents and Settings\Administrator> folder....?

All these links are of mp4, nothing indicates .f4m.
Where can I find the correct link ?
I am also having similar issues. I do not quite understand how to create/access/obtain the manifest file. i would like to restream the link that is caputured with the HDS Detector. where do i find this? I have been able to dl the file to my HDD and would like to now know how streaming is possible. thank you.

Hi KSV,

what tools do you need to try to break the encryption of HDS? I may give it a try.
I feel that it is important to enable playback on platforms without flash (FreeBSD etc.)

@ont
Video is encrypted with DRM, you can't decode it without specific key.

How do I download the following video:
Code:
Video Direct link:
http://www.nrk.no/embed/PS*93936

Video Embedded:
http://www.nrk.no/nyheter/verden/1.10889437
I have tested Adobe HDS Downloader but dont got any access to the file even I see the manifest(.f4m), the video extension and the "Seg" inside the links:

Code:

Have you even read the first post or wiki?

@IV
following is the info i posted long ago in now deleted thread. This is only related to custom encryption used by Akamai CDN (Packet type 10 & 11) not FlashAccess DRM (Packet type 40 & 41).

==========
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.
