Description

When trying to pull my recent livestream from Stretch, it failed due to a JSON read error. There also seems to be some Python errors. When downloading a YouTube video, the downloader seems to work correctly and the video file plays with no problem. I believe that this has to do with how Stretch is doing things on their backend. It should be a simple link switch in the extractor. Not sure though.

Here is the link to the video if needed: https://portal.stretchinternet.com/kwu/portal.htm?eventId=627944&streamType=video
