This project acts as a daemon-style folder watcher for converting any (LEGALLY OBTAINED) videos to .mp3 format. The program is extension agnostic and takes arguments of the form:

./ffmpeg_proc <input_dir> <output_dir>

The program will keep track of the files in the input_dir, and save these files as .mp3 to the output_dir. This means files can be dragged and dropped into the input_dir and the program will automatically perform conversion.

Install Elixir here: https://elixir-lang.org/install.html

ffmpeg must be installed either system-wide or downloaded to the directory where the program is run from. For system wide, simply do:

sudo apt-get install ffmpeg

Alternatively, your distribution of Linux may already have it installed.

mix escript.build
./ffmpeg_proc <input_dir> <output_dir>

To run on the sample video provided, simply do:

./ffmpeg_proc videos/ out/

Where out/ can be replaced by a directory of your choice.

This project comes with one youtube video as a sample in the videos directory.
