A bash script I wrote to remove audio from dash cam videos. Part of a larger system.

strip_audio_from_files.sh

#!/bin/bash

# So I got this dashcam and I run this script to remove audio because the
# camera itself is really badly designed. It does exactly as advertised for
# videos encoded as AVI.
# Usage: Run inside directory with AVI files that need to have audio removed
# ffmpeg is required. Duh.
