We announced a release of a final version of Smooth Streaming Plugin for Open Source Media Framework (OSMF). Please read Cenk's blog post for details.
Here is a quick blurb from Cenk's post:
We are pleased to announce that Windows Azure Media Services team released a RTW version of Microsoft Smooth Streaming plugin for OSMF. Using Smooth Streaming OSMF plugin, you can add Smooth Streaming capabilities to existing OSMF and Strobe Media Playback players and furthermore build rich media experiences for Adobe Flash Player endpoints using the same back-end infrastructure you use today to target Smooth Streaming playback to other devices like Win8 store apps, browser and so on.
