Help with finding the video URL

Hi, I am a Python enthusiast and sometimes try to write my own addon for video streaming web sites for which I don’t see any already existing addon. Recently I am coming across sites where I can’t find any iframe or any other clue to get the video (m3u8/mp4 etc) URL.

Following are the 3 such URLs I tried to get the video URL. Looking for your expert help to write some python code to get such complex URLs.
