 # What is This Script?
 # This script allows you to broadcast your AzuraCast radio signal to a remote video stream, using a 
 # static video file that loops in the background and dynamically writing the currently playing track
 # on top of that video file.
 #
 # This script replaces the previous "radio-video-stream" project, allowing you to manage files directly from
 # within AzuraCast and not requiring any changes to your Docker configuration at all.
 # 
 # To use this script, you must be running at least AzuraCast 0.19.0 or a later Rolling Release version.
 # 
 # Before Using This Script:
 #  - Upload a video file to a folder under your station's media library (in the example below, named "videostream")
 #  - Choose a font to display Now Playing data and upload a TTF version of that font to the same folder
 #
 # How to Use This Script
 #  - Copy the section below.
 #  - Visit your station's "Edit Liquidsoap Configuration" section (under "Broadcasting" in newer versions)
 #  - Paste the code into the bottom-most configuration section
 #  - Customize as necessary with your station's media directory and font specifications
 #  - Click "Save Changes" and then "Restart Broadcasting"
 #  - Enjoy!
