Adobe HDS (HTTP Dynamic Streaming) is a new technology to deliver video stream in fragments instead of one single stream. AdobeHDS.php script was created to download and stitch those fragments in single flv file. you need to pass some parameters (e.g. manifest) to the script to download videos. though finding those parameters is easy but doing so for multiple videos can easily become cumbersome job. This add-on was created to facilitate the automatic detection of those parameters and generate proper command line which you can simply paste in the console to download your video.
