I think the SDK part of your application would just log in and export the video stream to a temp file on the web server, in a place where it can be served from. Your web application would then point the video player (either a <video> element or something more sophisticated) at the url for that temp file. You'll need to clean up the temp files, and you'll want to make sure to consider security and privacy concerns - e.g. does there need to be access control to downloaded files, what if someone guesses a url, etc.
