Pacify

Shell script that extracts YouTube video audio and condenses it for passive language listening

Pacify downloads YouTube audio via youtube-dl and condenses it for a better passive listening experience.

POSIX compliant* *Require youtube-dl(python), ffmpeg, and dos2unix to be installed and in the PATH. Make sure that a symlink of python3 to python is made

ln -s /usr/local/bin/python3 /usr/local/bin/python

and that youtube-dl is the latest version (monthly release).

youtube-dl --version

This script has been tested on Ubuntu 20.04, Alpine 3.13.5, FreeBSD 12.2, and OpenBSD 6.8.

Running

chmod +x ./pacify

./pacify SuperTuxCart uWO5DISzMUA es

Note: This video might not work on OpenBSD, try the video you want instead

The command format is

pacify [file/directory name] [YouTube video ID] [subtitle language ID]
