#playlists #tilderadio #ezstream #icecast #DJing

I have recently reevaluated my robo DJ processes for my Tilderadio shows "DJ Kate's Tales From The Crates" and "DJ Kyoko Time". My old automation processes can be found here.

My new process now involves the following new processes:

  1. Random picking of a playlist from a playlist folder called "playlists";
  2. Plugging in the playlist in the ezstream xml file;
  3. Running ezstream;
  4. Moving the played playlist folder from "playlists" folder to a separate folder called "played" so it does not get picked again randomly;
  5. And finally, moving all the played playlists from the folder "played" back to the "playlists" folder where they can be picked again randomly once all of the playlists have been played.

Creating media files to make up a playlist, i.e. streaming the mix for the first time while recording it and then preparing the mix for restreaming by the robo DJ, remains unchanged (refer to "My Media Files" section of the old blog).

Updated: Random Picking Of A Playlist & Livestreaming It Using ezstream

The updated script ezstream_kate_random now looks like this:

#!/bin/bash
folder=`find /Users/gary/Music/radio/playlists/kate* -maxdepth 100 -type d | /opt/local/bin/gshuf | head -1`
sed -i .bak -e "s|.*<\/filename>|${folder}\/playlist.txt<\/filename>|g" /Users/gary/.ezstream/ezstream_kate.xml
/usr/local/bin/ezstream -c /Users/gary/.ezstream/ezstream_kate.xml

Moving The Played Playlist So That It Does Not Get Streamed Again

I have created a new script called mv_folder_kate to be executed after the stream is completed (a separate cron job). This action cannot be included in the first script as the stream will stop once the script starts executing the line that moves the folder (ezstream will suddenly lose the media files to stream as the mv line will execute even before ezstream finishes streaming).

#!/bin/bash
last_playlist=$(grep "playlist.txt" /Users/gary/.ezstream/ezstream_kate.xml | sed 's/^.*\/Users\/gary\/Music\/radio\/playlists\/kate/\/Users\/gary\/Music\/radio\/playlists\/kate/' | sed 's/\/playlist.txt<\/filename>//')
mv "$last_playlist" /Users/gary/Music/radio/playlists/played/kate/

Moving All Played Playlists Back to Original Folder Once There Is No More Playlist To Stream

This is accomplished by a new script called test_kate:

#!/bin/bash
if ls /Users/gary/Music/radio/playlists/kate* >/dev/null 2>&1; then
		exit 0
	else
		mv /Users/gary/Music/radio/playlists/played/kate/* /Users/gary/Music/radio/playlists/
fi
