YouTubeCrawler
Go-based automation utility that downloads YouTube videos
...The architecture follows a command-pattern setup: tasks implement a common interface and are scheduled and executed with concurrency controls (maximum goroutines customizable). It assumes a Linux environment with SSR proxy support, and requires the user to pre-install youtube-dl and ffmpeg. With its focus on automation, the tool is useful for easily archiving multilingual subtitles, prepping content for editing, or creating reference versions of YouTube videos.
