Dreamweaver gives you the following options for delivering Flash Video to your site visitors:
Progressive Download Video downloads the Flash Video (FLV) file to the site visitors hard disk and then plays it. Unlike traditional "download and play" methods of video delivery, however, progressive download allows the video file to start playing before the download is complete.
Streaming Video streams the Flash Video content and plays it on a web page after a short buffer period that ensures smooth playback. To enable streaming video on your web pages, you must have access to Macromedia Flash Communication Server.
You must have an encoded Flash Video (FLV) file before you can use it in Dreamweaver. You can insert video files created with two kinds of codecs (compression/decompression technologies): Sorenson Squeeze and On2.
After inserting a Flash Video file in a page, you can insert code in the page to detect whether the user has the correct version of the Flash Player to view the Flash Video. If they dont have the correct version, they will be prompted to download the latest version of Flash Player. For more information, see Detecting the Flash Player version to view the Flash Video.
