Properties

Property Type Description

delayOutputMs?

number

(Optional) By default, the program date time or event start time will be based on the timestamp of the first video packet received by Norsk in a stream.

Assuming minimal latency in Norsk itself, this behaviour is fine - but encodes and composition or synchronisation with external streams can then result in players requesting segments that don’t exist yet

delayOutputMs can be used to push the timestamp forwards so that players can calculate the edge of the stream accurately.

This number should match the delayOutputMs of other streams which will be served within the same master playlist

destination

CMAFDestinationSettings

The destination CMAFDestinationSettings for this stream to be published to

hlsCacheDirectory

string

A local directory in which to store the segments while they’re available

maximumPlaylistSegments

number

The maximum number of segments to display in a single generated playlist

retentionPeriodSeconds

number

How long to retain data for this playlist (this information can end up in the playlist to let the client know what the availability window is, for example)

segmentDurationSeconds

number

The target segment duration in seconds, Norsk will split subtitles over multiple segments in a compliant manner if necessary
