Have you seen my previous screencast (Intro in Derivatives API)?
In this screencast I show how to easily support HTML5 <video> tag on all major browsers using two derivatives of source video, created by Derivatives API. This is a sample feature. It's purpuse is to show how Media Derivatives API works and should not be used in production envirnonment.
In this screencast I want to show you basic workflow with Derivatives API, my Summer of code 2011 project. Derivatives API works with Media ecosystem and it's purpuse is to provide a solid and extensible framework for automated file derivations.
You will also see how different plugins work and get an idea what should be possible to do with them.
