Download videos from Microsoft Stream with Destreamer

#destreamer #powershell #prompt #git

Presentation

Hello everyone
In these last days I participated in some online lectures that were recorded and made available by Microsoft Stream. Many of these talks, I would like to save offline, to watch during a trip or even listen as a podcast.
There are hundreds (if not thousands) of tools that download videos from YouTube, all online, but unfortunately, none for Microsoft Stream.

It was then that I came across this repository on GitHub and decided to share it with the dev.to community. Enjoy ;)

Prereqs

NodeJS
NPM
FFMPEG
Git

How to build



$ git clone https://github.com/snobu/destreamer
$ cd destreamer
$ npm install
$ npm run build

Use

Note: If you are running the destreamer in a Windows environment, it is recommended to use the PowerShell or Prompt scripts.

For use, you can pass some parameters, all of them can be consulted with the destreamer (consult the platform you are using to use the correct extension)

For example, I had to download some videos and make them manually it would be laborious, so I copied the links and put them in a notepad inside the installation folder.
From there, I ran the command at a Windows prompt:



destreamer.cmd -u USER@EMAIL.COM -f links.txt -k true -x true --skip

-u: I pass the user to login to Microsoft Stream (it is still necessary to enter the password).

-f: It is the file that contains my links, they must be placed one per line. If you want to download a single file, just use the -i option and pass the direct link to the video (read the help or documentation).

-k: I set it to true to keep the session cookie I logged in. Thus, it is not necessary to enter the password in any of the subsequent downloads. Complete automation.

-x: The destreamer tool presents a brief preview of the video being downloaded. To remove this, I set this option to true. The output log is cleaner.

--skip: If any video fails, I can run this entire command again and this parameter will validate that the video has already been downloaded and will ignore it for download.
