What if you built a nice, custom FLV player in Flex and wanted to embed the player in an HTML page and have it star playing a specific video? How could you easily do that without tweaking the MXML each time with the path to the FLV or calling a server-side script to somehow determine the video you wanted to play? Well, one of the easiest solutions is to tweak the generated embed code and pass in any custom variables you wanted using “FlashVars”.
No idea what I’m talking about? Well, check out the following Flex 2.0.1 docs for more of a background: “Using flashVars” and “Using the Application.application.parameters object”.
