Flex, Flash Media Server and RIA concepts

Flex Research

Rich Internet Applications are popping up all over the web. When I first saw them, I thought, “I want to do that too!” I started from level 0 when learning how to use Flex and Flash Media Server to build RIAs, and I had a lot of questions:

Defining Flex

Flex is confusing. Like Flash, it can mean many different things, depending on the conversation. If you are familiar with the multiple meanings of “Flash,” it will help you understand “Flex.” As you are probably already aware, “Flash” can refer to:

  1. the software – an IDE, such as Flash MX 2004
  2. an animation or game built from the software – like homestarrunner.com
  3. the .swf – the most common compiled file created by the software
  4. the player – such as Flash Player 10, a web browser plug in

Its logic is driven by a script language called ActionScript. “Flex” can mean:

  1. the software – an IDE, such as Flex Builder 3
  2. the framework – the SDK, such as Flex SDK
  3. Rich Internet Applications built from the software

Flex creates .swf files for the client, just like Flash. It uses Flash Player, just like Flash. Its logic is driven by ActionScript and can also incorporate a server-side language, such as Coldfusion, PHP or asp.NET.

The applications I develop for my company will use a symphony created from Flex, Flash Media Server, ActionScript 3 and asp.NET.

The Flash Media Server

FMS is a powerful tool that is simple to implement. If you want to manipulate online video and deliver it in an efficient manner without knowing much about video, FMS is a good, albeit expensive, answer. Dynamic video streaming and live streaming video with fast setup and use. Once FMS was installed it was easy to jump right in and begin adding stream-on-demand videos for our clients. The Flash Media Encoder allows you to start streaming live video with less than 5 minutes of time setting up the program. The major flaw of the Flash Media Encoder is that it supports Windows only- no Linux or Mac version of the software is available.

Rich Internet Application Development – Why FMS  and Flex?

FMS makes it easy to deploy video as well as coordinate any real-time tasks by using RTMP. Flex allows rapid prototype development thanks to the multitude of components and libraries available in the framework. Create your application in Flex, publish the resulting .swf file, have it coordinate with FMS for any real-time tasks you have, and voilà! you just produced: an online video chat, a live auction complete with audio, video and real-time bidding, or a live business presentation across countries.
