Sauce+ downloader

This is a Sauce+ video downloader, written in nushell

Dependenices

There is a nix flake w/ devshell to provide all dependencies, but alternatively, the following should be installed manually:

• nushell (duh)
• openssl
• ffmpeg

How to use

1. Open the video to download in a browser
2. Open devtools, switch to network tab
3. Refresh the page
4. Look in the list of request for a few important ones, listed below:

Request file	Description	What to do with it
video?id=...	The text after ?id= in the file is the GUID of the media file	Replace GUID in the below command with the text after ?id=. It should look something like tqHgbrNbF5
watchKey?token=...	The response of this contains the encryption key of the downloaded media	Replace ENCRYPTION_KEY in the below command with the response value. It should look something like gdR/nTT3nHAlXEIVPJ6cPA==.
chunk.m3u8?token=...	The response of this contains the list of files to download	Copy the entire text and paste it into a local file, probably named chunk.m3u8. It should start with #EXTM3U.

5. Run ./downloader.nu get-video GUID ENCRYPTION_KEY
6. Wait for the download. If any errors occur while downloading or decrypting, you should probably run it again.
7. The downloaded file should be placed at out.mkv.

TODOs

• Make an HAR parser to remove manual labor of reading devtools
• Clean up some janky nushell code sitting around
