Saves Microsoft Stream videos for offline enjoyment

v2.0 Release, codename Hammer of Dawn^TM

This release would not have been possible without the code and time contributed by two distinguished developers: @lukaarma and @kylon. Thank you!

What's new

• Major code refactoring
• Dramatically improved error handling
• We now have a token cache so we can reuse access tokens. This really means that within one hour you need to perform the interactive browser login only once.
• We removed the dependency on youtube-dl
• Getting to the HLS URL is dramatically more reliable as we dropped parsing the DOM for the video element in favor of calling the Microsoft Stream API
• Fixed access token lifetime bugs (you no longer get a 403 Forbidden midway though your download list)
• Fixed a major 2FA bug that would sometimes cause a timeout in our code
• Fixed a wide variety of other bugs, maybe introduced a few new ones :)
• Automatic authentication for polimi student in this repository

Disclaimer

Hopefully this doesn't break the end user agreement for Microsoft Stream. Since we're simply saving the HLS stream to disk as if we were a browser, this does not abuse the streaming endpoints. However i take no responsibility if either Microsoft or your Office 365 admins request a chat with you in a small white room.

Prereqs

• Node.js: You'll need Node.js version 8.0 or higher. A GitHub Action runs tests on all major Node versions on every commit.
• npm: usually comes with Node.js, type npm in your terminal to check for its presence
• ffmpeg: a recent version (year 2019 or above), in $PATH or in the same directory as this README file (project root).
• git: one or more npm dependencies require git.

Destreamer takes a honeybadger approach towards the OS it's running on. We've successfully tested it on Windows, macOS and Linux.

Limits and limitations

Make sure you use the right script (.sh, .ps1 or .cmd) and escape char (if using line breaks) for your shell. PowerShell uses a backtick [ ` ] and cmd.exe uses a caret [ ^ ].

Note that destreamer won't run in an elevated (Administrator/root) shell. Running inside Cygwin/MinGW/MSYS may also fail, please use cmd.exe or PowerShell if you're on Windows.

WSL (Windows Subsystem for Linux) is not supported as it can't easily pop up a browser window. It may work by installing an X Window server (like Xming) and exporting the default display to it (export DISPLAY=:0) before running destreamer. See this issue for more on WSL v1 and v2.

Download a video -

$ ./destreamer.sh -i "https://web.microsoftstream.com/video/VIDEO-1"

Download a video and speed up the interactive login by automagically filling in the username -

$ ./destreamer.sh -u user@example.com -i "https://web.microsoftstream.com/video/VIDEO-1"

Download a video to a custom path -

$ ./destreamer.sh -i "https://web.microsoftstream.com/video/VIDEO-1" -o /Users/hacker/Downloads

Download two or more videos -

$ ./destreamer.sh -i "https://web.microsoftstream.com/video/VIDEO-1" \
                     "https://web.microsoftstream.com/video/VIDEO-2"

Download many videos but read URLs from a file -

$ ./destreamer.sh -f list.txt

You can create a .txt file containing your video URLs, one video per line. The text file can have any name, followed by the .txt extension.

Passing --username is optional. It's there to make logging in faster (the username field will be populated automatically on the login form).

You can use an absolute path for -o (output directory), for example /mnt/videos.

Expected output

Windows Terminal -

iTerm2 on a Mac -

By default, downloads are saved under videos/ unless specified by -o (output directory).
