This project was inspired by https://github.com/snobu/destreamer, rewritten into Python from https://github.com/sup3rgiu/MStreamDownloader.

Latest python script is available here on github.

You need Python 3.x to run the script.

Extract the latest ffmpeg release (download from https://github.com/BtbN/FFmpeg-Builds/releases) and aria2c (download from https://github.com/aria2/aria2/releases) either into arbitrary directory and don't forget to add paths to PATH environtment variable, or simply into the directory containing the python script.

On a fresh Debian install, run

sudo apt-get update
sudo apt-get install ffmpeg aria2 python3 python3-pip

Make sure you have installed all required modules. Most of them should be included in default python3 installation, the rest can be installed using pip:

pip install m3u8 nest_asyncio pyppeteer requests_async termcolor prompt_toolkit

The function async def defaultLogin(page, email, password) tries to find specific HTML elements in the login form on Microsoft Stream website. It is usually composed of default Microsoft login form and a form specific for your university/company. Element identifiers used in the python script are working for the CTU login, but you will probably need to change them slightly.

Elements corresponding to input[type="email"], input[type="submit"] and div[id="usernameError"] are common as they are located at the default Microsoft login form. When username is entered and submit button pressed the form brings you to your university/company login form - username is copied automatically, but elements input[type="password"], span[id="submitButton"] and span[id="errorText"] may be different in your case. The easiest way to find the correct identifiers is to perform the login manually with Chrome DevTools opened and focused on the required elements, then you should be able to find them in the HTML code. If the login is successful it will redirect you back to Microsoft login form to choose if password should be remembered, the "No" button corresponds to input[id="idBtn_Back"]. That is the end of the login process followed by a redirection to the Microsoft Stream homepage.
