SrtPcapInputSettings interface

Settings for an SRT pcap input node.

Experimental: passive SRT probe from a packet capture. The node replays the SRT sessions found in a classic pcap file as if they had been sent to an SRT listener: one connection per session, the same connection callbacks and health events as NorskInput.srt() in listener mode, and the node closes once the capture has been delivered. see: NorskInput.srtPcap()

Events

Property Type Description

onConnection?

( streamId: string, index: number, remoteHost: string) ⇒ SrtConnectionResult

(Optional) Called for each SRT session found in the capture, as SrtCommonInputSettings.onConnection. remoteHost is the sender’s ip:port.

onConnectionHealth?

(health: SrtConnectionHealth) ⇒ void

(Optional) Called periodically with per-connection health, as SrtInputSettings.onConnectionHealth.

onConnectionStatusChange?

( status: SrtInputStatus, sourceName: string | undefined, index: number, health?: InputHealthStatus) ⇒ void

(Optional) Called when a connection’s status has changed (e.g. when a session of the capture has ended)

Properties

Property Type Description

fileName

string

Absolute path of a classic pcap file on the engine host

healthSampling?

HealthSamplingSettings

(Optional) Per-connection health sampling, as SrtInputSettings.healthSampling. On by default. A session’s final statistics are reported for three health intervals after its end, before the connection is reported as disconnected.

healthThresholds?

HealthThresholdsSettings | "recommended"

(Optional) Opt-in thresholds for degraded / recovered, as SrtInputSettings.healthThresholds.

onRecording?

(event: InputRecordingEvent) ⇒ void

(Optional) Events from the recording SourceRecordingSettings started

onSourceTimeStateChange?

(sourceTimeState: SourceTimeState) ⇒ void

(Optional) Called when either a VITC timecode is detected, or having previously detected a timestamp it stops being present

onTsContext?

(context: SrtTsContext) ⇒ void

(Optional)

onTsTable?

(table: SrtTsTable) ⇒ void

(Optional) Callback to be invoked on receiving a TS PSI/SI table/section

playbackRate?

number

(Optional) Playback rate multiplier: capture time is replayed at this many times realtime. Defaults to 1 (realtime).

programFilter?

number

(Optional) Optionally filter a single program from MPTS at decode time

sourceRecording?

SourceRecordingSettings

(Optional) Record each source’s bytes as they arrive, from the start: see SourceRecordingSettings

statsPollIntervalMs?

number

(Optional) Interval in milliseconds at which to sample the per-connection SRT statistics. When unspecified a default is used.

timeDomain?

TimeDomain

(Optional) Optional time-domain configuration, as SrtCommonInputSettings.timeDomain.
