Adobe Flash HTTP Dynamic Streaming

Adobe Flash HTTP Dynamic Streaming


 
One of the on-line TV service providers in UK, 4oD, has started to use http dynamic streaming and in consequence I can no longer even watch the programmes using Firefox on openSUSE 12.1 Linux.

Adobe state that their flash software should work but mine does not so I can neither stream or watch this channel anymore.

Surely some other linux users have noticed this problem. Can anybody help please?

The file format spec provided in one of the replies is the manifest file format specification - F4M. The actual f4f file format specification is only available under NDA. We have a white paper that we are working on @ Adobe, and once that is out, I can update you. Stay tuned.

Where are the coders and the reverse engineers if it comes to that? I am not thinking just of downloading, I can't even watch some TV shows on line now.

I do not believe there is no solution out there, just that I cannot find it.

Please could somebody who knows share their knowledge.

The RTMP "specification" was released in June 2009 by Adobe.

So they opted for "security through obscurity"

The official F4F specification is only available , as of now, through an NDA. The following thread gives all the details : http://forums.adobe.com/thread/685558

They're only using it for some videos. njtaylor has done quite a lot of investigation into this, see this issue at Google Code: http://code.google.com/p/get-flash-v...=379&start=100. The main problem now is that not only does this use dynamic streaming, it's also encrypted. Need to find the key.
