Does HTTP Dynamic Streaming require ActionScript, or is it a function of the server?
Since HTTP Dynamic Streaming does not utilize RTMP or Flash Media Server, the stream transition logic, the commands to switch streams, and the determination to do so all come from ActionScript commands in the client SWF application. The Flash and Flex ActionScript developer includes logic in the application to monitor download and playback statistics and to switch from the old stream to the new stream when appropriate. It is recommended that players utilizing HTTP Dynamic Streaming be built using the OSMF, as all the logic for parsing manifest files and sequencing the playback of media fragments is built into the framework.
