This component creates, and optionally publishes, a HLS/TS media playlist for a single stream

Component Configuration

A unique identifier for the component instance

displayName

The name shown in the Studio UI of this component

name

The name of the playlist

sessionId

Generate a unique session id per run to avoid cache collisions (default: false)

Each playlist will be published within a 'group', change this if you need multiple playlists for the same stream

segments

Detailed segment configuration

<COMPONENT_ID>_SEGMENTS

destinations

Destination to publish to (default: [])

<COMPONENT_ID>_DESTINATIONS

The publishing state of this endpoint by default on start-up (default: "enabled")

<COMPONENT_ID>_INITIALSTATE

notes

Additional notes about this component

Options with an environment override can be set when Studio starts, without editing the workflow. <COMPONENT_ID> is this component’s id in your workflow, uppercased, with spaces and dashes replaced by underscores and other punctuation removed — a component named SRT Input reads SRT_INPUT_PORT. Renaming a component changes its id, and so changes these variable names.

Segments

Option Description Required

retentionPeriod

How many seconds of data to retain for playback in media playlists (default: 60)

defaultSegmentCount

How many segments to display in a default playlist (0 means show all) (default: 0)

targetSegmentDuration

How many seconds should be in each segment (default: 4)

targetPartDuration

For low latency playlists, what size parts should be generated in seconds (default: 1)

audioSegmentStrategy

Detailed segmentation strategy. Must be configured to match segment duration (after rounding) or invalid playlists may be generated (default: {"type":"default"})

videoSegmentStrategy

Detailed segmentation strategy. Must be configured to match segment duration (after rounding) or invalid playlists may be generated (default: {"type":"default"})

integralSegmentDuration

Round segment durations in playlist to integers instead of true decimal value. Possible workaround for certain player issues. (default: true)

holdBackSegments

How many segments back should a player start

holdBackParts

How many parts back should a player start

lowLatency

Produce low-latency HLS (EXT-X-PART / blocking reload). Turn this off for standard, CDN-cacheable playlists with no parts — recommended when delivering through a caching CDN. (default: true)
