Thank you! [Politecnico di Milano][polisite] students may want to use this fork over at https://github.com/SamanFekri/destreamer which is a specialized implementation of this project with automatic logon. ## 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 :) ## 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**][node]: You'll need Node.js version 8.0 or higher. A GitHub Action runs tests on all major Node versions on every commit. One caveat for Node 8, if you get a `Parse Error` with `code: HPE_HEADER_OVERFLOW` you're out of luck and you'll need to upgrade to Node 10+. - **npm**: usually comes with Node.js, type `npm` in your terminal to check for its presence - [**ffmpeg**][ffmpeg]: a recent version (year 2019 or above), in `$PATH` or in the same directory as this README file (project root). - [**git**][git]: one or more npm dependencies require git. Destreamer takes a [honeybadger](https://www.youtube.com/watch?v=4r7wHMg5Yjg) 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][xming]) and exporting the default display to it (`export DISPLAY=:0`) before running destreamer. See [this issue for more on WSL v1 and v2][wsl]. ## How to build To build destreamer clone this repository, install dependencies and run the build script - ```sh $ git clone https://github.com/snobu/destreamer $ cd destreamer $ npm install $ npm run build ``` ## Usage ``` $ ./destreamer.sh Options: --help Show help [boolean] --version Show version number [boolean] --videoUrls, -i List of video urls [array] --videoUrlsFile, -f Path to txt file containing the urls [string] --username, -u [string] --outputDirectory, -o The directory where destreamer will save your downloads [default: videos] [string] --outputDirectories, -O Path to a txt file containing one output directory per video [string] --noExperiments, -x Do not attempt to render video thumbnails in the console [boolean] [default: false] --simulate, -s Disable video download and print metadata information to the console [boolean] [default: false] --verbose, -v Print additional information to the console (use this before opening an issue on GitHub) [boolean] [default: false] --noCleanup, --nc Don't delete the downloaded video file when an FFmpeg error occurs [boolean] [default: false] --vcodec Re-encode video track. Specify FFmpeg codec (e.g. libx265) or set to "none" to disable video. [string] [default: "copy"] --acodec Re-encode audio track. Specify FFmpeg codec (e.g. libopus) or set to "none" to disable audio. [string] [default: "copy"] --format Output container format (mkv, mp4, mov, anything that FFmpeg supports) [string] [default: "mkv"] ``` We default to `.mkv` for the output container. If you prefer something else (like `mp4`), pass `--format mp4`. Download a video - ```sh $ ./destreamer.sh -i "https://web.microsoftstream.com/video/VIDEO-1" ``` Download a video and re-encode with HEVC (libx265): ```sh $ ./destreamer.sh -i "https://web.microsoftstream.com/video/VIDEO-1" --vcodec libx265 ``` Download a video and speed up the interactive login by automagically filling in the username - ```sh $ ./destreamer.sh -u user@example.com -i "https://web.microsoftstream.com/video/VIDEO-1" ``` Download a video to a custom path - ```sh $ ./destreamer.sh -i "https://web.microsoftstream.com/video/VIDEO-1" -o /Users/hacker/Downloads ``` Download two or more videos - ```sh $ ./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 - ```sh $ ./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). ## Contributing Contributions are welcome.
