Breaking Change Warning

SCTE input handler

If you use the feature that triggers an AppleScript when an SCTE message is received, you will need to update your AppleScript to follow the new syntax introduced with the addition of Segmentation Descriptor support. More info...

Time markers (Auto Start) - Clocked Items

We’ve updated how Time Markers work (the feature that lets you set a start time on a clip). Previously, only one playlist at a time could be set to automatically start clips using the clock icon at the top of the playlist. Now, you can enable this option on multiple playlists.

However, if you are playing a playlist with the clock option enabled and then start another playlist, the clock option on the previous playlist will automatically be disabled. This ensures that during events like breaking news—when you start a new playlist—the earlier playlist will not continue triggering its scheduled items.

When the breaking news playlist is finished, simply re-enable the clock option on the original playlist. You can do this manually in the playlist or by using the new REST API call:

GET /playback/clocked_items?enabled=1

This call enables the clock option on all playlists.
