Testing out the sample code

The first thing I did was try out the examples straight from the magazine. This was straightforward. The samples didn’t build anything too advanced but I noticed something. It didn’t take very many lines of code to get the video playing. Most of the code was for adding buttons and making them call a single function in the OSMF API. As usual when doing samples from an article I decide to tweak it to see has intuitive it was to do things. Adding and customizing simple playback controls and capabilities was a breeze. I only needed to check the documentation to make sure my assumptions were true, which they were in most cases. For a basic custom player, this thing is extremely easy to use.

Looking under the hood

The second thing I did is something I like to do with a framework I’m looking at, skim over the documentation. This consists of going through each package and seeing what classes are where. For the most part I will click into each classes documentation to find out what the class is meant for. Sure, this has me look at a lot of helper classes that I may never use ( which is a good learning exercise ), but it also has me find obscure classes that might be quite useful in a pinch.

One class that interested me both for educational and practical reasons was the ListenerProxyElement class. It is actually quite beautiful in its simple use. It is a class that is meant to be extended. The class itself sets up all the listeners for a MediaElement and has them trigger hook functions that you override to handle these events with custom code. I foresee using this in many projects. There are quite a few other things taken care of in this framework, such as handling of a video player that is sized differently from the video content.

Overall, Adobe ( who is in charge of this open source project ) has put together a very useful, intuitive and extensible framework that is still in the early stages. I’m looking forward to see what types of media players I can build now that so much is already handled for me. Is there anything you want to know about OSMF? Have you already used it on a project? If you have can we see your work (and hopefully code)?[ad#Adobe Banner]
