LiveEventGetTrackIngestHeartbeatsResult

Get live event track ingest heart beats result.

Name	Type	Description
value	LiveEventTrackEvent[]	The result of the get live event track events.

LiveEventTrackEvent

The live event track event.

Name	Type	Description
data	LiveEventTrackEventData	Event data.
eventTime	string	The time event raised.
eventType	LiveEventTrackEventType	The type of the track event.

LiveEventTrackEventData

The live event track ingest heart beat event data.

Name	Type	Description
bitrate	integer	Bitrate of the track.
discontinuityCount	integer	Number of discontinuities detected in the last 20 seconds.
healthy	boolean	Indicates whether ingest is healthy.
incomingBitrate	integer	Calculated bitrate based on data chunks coming from encoder.
ingestDriftValue	string	Indicates the speed of delay, in seconds-per-minute, of the incoming audio or video data during the last minute. The value is greater than zero if data is arriving to the live event slower than expected in the last minute; zero if data arrived with no delay; and "n/a" if no audio or video data was received. For example, if you have a contribution encoder sending in live content, and it is slowing down due to processing issues, or network latency, it may be only able to deliver a total of 58 seconds of audio or video in a one-minute period. This would be reported as two seconds-per-minute of drift. If the encoder is able to catch up and send all 60 seconds or more of data every minute, you will see this value reported as 0. If there was a disconnection or discontinuity from the encoder, this value may still display as 0, as it does not account for breaks in the data - only data that is delayed in timestamps.
lastFragmentArrivalTime	string	The last timestamp in UTC that a fragment arrived at the ingest endpoint.
lastTimestamp	string	Latest timestamp received for a track in last 20 seconds.
nonincreasingCount	integer	Number of data chunks with timestamps in the past that were received in last 20 seconds.
overlapCount	integer	Number of data chunks that had overlapped timestamps in last 20 seconds.
state	string	State of the live event.
timescale	string	Timescale in which timestamps are expressed.
trackName	string	Name of the track.
trackType	LiveEventTrackEventTrackType	Type of the track.
transcriptionLanguage	string	The language code (in BCP-47 format) of the transcription language. For example, "de-de" indicates German (Germany). The value is empty for the video track heartbeats, or when live transcription is turned off.
transcriptionState	string	This value is "On" for audio track heartbeats if live transcription is turned on, otherwise you will see an empty string. This state is only applicable to track type of "audio" for Live transcription. All other tracks will have an empty value.
unexpectedBitrate	boolean	If expected and actual bitrates differ by more than allowed limit in last 20 seconds.

LiveEventTrackEventTrackType

Type of the track.

Name	Type	Description
audio	string
video	string

LiveEventTrackEventType

The type of the track event.

Name	Type	Description
TrackEvent/IngestHeartbeat	string	Track heartbeat received.
