Liquidsoap 2.1 Video Stream with HLS

video_stream.liq

# 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!

Can anyone help me set this up please
Yes, I am

@radiorecordua can u help me pls?
there are 5 section where i can paste this script. is it suppose to be in the lowest one under "# Remote Relays"?
should i join the url and key like this syntax? stream_key = "rtmp://YOUR RTMP URL/STREAM-KEY"

@radiorecordua hi! good afternoon and thank you for the quick response!
I just modified and pasted it and in the save I'm getting error: "At line 91, char 16: Error 2: Parse error" if I counted correctly it suppose to be one of those lines: def add_nowplaying_text(s) = or def mkfilter(graph)
just double checking cause I'm not sure, should it goes in the lowest script section? under the line "# Remote Relays" in azuracast liquidsoap overall script?
thank you for your time and help!

@radiorecordua thanks again,
it seems we have got different versions, mine is v0.20.4 Stable. which is yours?
do you find it under the main menu under broadcasting -> edit liquidsoap configuration? mine looks different
