Understanding video formats and controlling video volume in Flash Lite 3.x
As mobile devices become more sophisticated, developers continue to stretch the boundaries of the content they deliver to handsets. Video delivery is one avenue that has a promising future in mobile devices, but there is still much trailblazing to be done to successfully present it over the current mobile networks. Recently I came across a question in the forums that asked for a method to control the volume of an embedded video in Flash Lite 2.0. This is clearly not possible. However, the challenge intrigued me and I investigated possible strategies for controlling the sound of digital video in mobile applications. I am writing this article to elaborate my findings in this area and to share a workaround that can be accomplished in Flash Lite 3.0 with the online community.
In addition, I'll also explain the different types of video formats that are involved (native and device video) and provide information about the currently supported codecs available for mobile developers.
Requirements
In order to make the most of this article, you'll need the following software and files:

Prerequisite knowledge
