Triggering Blackouts via Event Adaptors

You can easily trigger a blackout via the Event Adaptors by filling in the SongInfo object.

For example the following will trigger a 5sec blackout when using the HTTP event adaptor. http://localhost:8181/?songtype=B&duration=5000&filename=test.m3u&intro=test.mp3&outro=test.mp3

Key fields:

• songtype: Set value of 'B' to signal blackout. (Required)
• duration: Duration of blackout in milliseconds (Required)
• filename: The location of a M3U playlist file containing a list of tracks to play during the blackout. (Required)

  If you do not want any audio, write silence as the file.

• intro: Intro file to play at start of blackout. (Optional)
• outro: File to play once blackout ends. (Optional)
• artist, title and other normal song fields can also be specified for display purposes. (Optional)

You can also trigger the end of a blackout by using a songtype value of 'Z', i.e. http://localhost:8181/?songtype=Z
