This plug-in:

• Collects "Now & Next" signals from RDAirPlay (Rivendell's automation software)
• Creates a /playlist Wordpress page (which you can edit to change the title and the header text) where the user can browse Rivendell's playlist.

We have 3 roles for the machines involved:

• a player, the one running RDAirplay, will send now & next signals via UDP to the transmitter.
• a transmitter, which runs our listen_now_and_next_and_post_to_wordpress.sh script. This machine can be the player.
• a wordpress server, which will receive artist/title signals from the transmitter.

TODO

• transmitter script as a system service
• i18n https://codex.wordpress.org/I18n_for_WordPress_Developers
• drop table in https://developer.wordpress.org/reference/functions/register_uninstall_hook/

Installation

On the player:

• launch RDAdmin
• click Manage hosts
• select your player
• click the RDAirplay button
• click the Configure Now & Next parameters button
• In the Master log (at the top) section, enter the IP of the transmitter. The UDP port number should match the PORT written in the transmitter script.
• In UDP string enter %a___%t%R (that's 3 underscores)
• Click OK to close all this
• Restart RDAirplay on the player.

On the WordPress server:

• Copy the plug-in forlder in your Wordpress installation (to /wp/wp-content/plugins).
• Log in Wordpress as an admin and go to the extensions page.
• Find "Rivendell Now&Next collector and browser" in the list, and click on "activate".
• In the left menu browse to "Settings" and "Rivendell".
• Set a secret key: choose something long.

On the transmitter (assuming this is a freshly installed CentOS7, where we listen on port 2345):

• sudo yum install nmap-ncat
• sudo firewall-cmd --permanent --zone=public --add-port=2345/udp
• sudo firewall-cmd --reload
• change listen_now_and_next_and_post_to_wordpress.sh: change at least WORDPRESS_BASE_URL and KEY, according to what you set above.
• copy this file to the transmitter machine, log in and run the script with ./listen_now_and_next_and_post_to_wordpress.sh &> listen_now_and_next_and_post_to_wordpress.log &
• type disown %1 before logging out
