Yusef library


Yusef is a mysterious "Unite Service Framework " (there was "Access Denied" on that ever since this link surfaced).

Although the links had been published, I don't think anyone actually saw what this was.

You can find the folder "Yusef" inside of mediaplayer[.us] ("C:\Program Files\Opera\unite\mediaPlayer.us" is a .zip file, open with WinRar) and many others. Unfortunately it's still unclear whether Yusef is a ready library or just a collection of some scripts.

It contains reference to many "hacks", so it might not be production ready.

Inside Yusef

Inside we can find classes and functions for stuff like:

Here and below "\mediaplayer\" means
C:\Program Files\Opera\unite\mediaPlayer.us
ADS(ASD?) Streams: (WTH is that? Maybe it's this , cool!)
\mediaplayer\yusef\adstreams

Resource Fetcher:
\mediaplayer\yusef\asdstream\resourcefetcher\

JSON helpers:
\mediaplayer\yusef\public_html\activityStream\dependsOn\json.js

Reset function

Static images serving - I couldn't make it work, so I modified it to work with "/application/" mount point (would be very easy to modify for others).
