This is a very incomplete python library for downloading streams in the Adobe HDS format, heavily inspired by K-S-V's AdobeHDS.php (https://github.com/K-S-V/Scripts/blob/master/AdobeHDS.php). It is a work in progress, as is my understanding of HDS streams and the Adobe Flash Video file format, and a lot of this code will change.
tl;dr: Move on and pay no attention to this mess.
