Working with splice inserts
Splice inserts inserted by the REST API are always of type “ad avail.”
You can:
-
Insert a SCTE-35 ad avail of type splice_insert. See Insert a new splice insert message.
-
Get the timecode of the content that is currently being processed. This data can be useful to determine the start time you need to enter in the command. See Get current time.
-
Insert an end time in an ad avail. See Insert an end time in an existing ad avail.
-
Cancel a SCTE-35 ad avail that is pending (the start time has not yet been reached). See Cancel a pending ad avail.
Effect of these commands
These commands modify the data stream as it is being encoded.
Their precise effect on other parts of the content depends on how the event is set up, as described in earlier chapters of this guide. So it depends on the Ad Avail mode, whether manifest decoration is enabled, blanking and blackout are enabled, and whether passthrough is enabled.
