Download age-restricted videos on YouTube

2022 UPDATE: It's better to use the YT-DLP fork of youtube-dl at this point. You can always make an alias for yt-dlp like so: alias youtube-dl='/usr/local/bin/yt-dlp' (make sure to replace /usr/local/bin/ with your actual yt-dlp path).

YouTube has recently blocked age-restricted videos from being downloaded. You can use the youtube-dl's --cookies flag to pass your stored cookie preferences to the command to bypass this.

• Install a Chrome extension like Get Cookies.txt to get your browser's cookies.
• Install youtube-dl from source, or use Python 3's PIP package manager to install it.
• Obtain a copy of your browser cookies stored as a .txt file.

Basic youtube-dl command is: youtube-dl "https://www.youtube.com/watch?v=VIDEO_ID_HERE".

Make sure to do the following first:

• Ensure the python3 command is working and actually runs a version of Python 3.x.
• Make sure that the path to your cookies file is correct.
• Make sure that you have the latest version of youtube-dl installed (youtube-dl --version).
• Ensure the absolute file path for the youtube-dl binary or installation (In a UNIX-like terminal use which youtube-dl).

Multi-Architecture Cross-Compatible Docker Setup for FFmpeg

Here's a Docker setup I used to help speed up FFmpeg in the containers by using different compiled binaries for each respective architecture. If someone knows of a better way to do this, or a cleaner way to do this, please let me know.

I've tested this on Ubuntu and Apple Silicon host machines.
