Downloading YouTube Videos with Elixir

#elixir #youtube #ytdlp #exyt

We recently had to develop some features that involved downloading videos from YouTube.

After some research, we found YT-DLP([https://github.com/yt-dlp/yt-dlp])

yt-dlp is a fork of youtube-dl based on the now inactive youtube-dlc. The main focus of this project is to add new features and patches while staying up to date with the original project.

From this came the idea of writing a simple wrapper around Elixir to facilitate integration with our stack.
