Emitted each time the integer SVTA MQA-VIDEO score ([0..100]) changes. Score is computed from the upstream frame’s raw metrics using the shared aggregation in Avp.Types.QualityMetrics (see MqaVideoWeights defaults).

QualityReportingSignalLost

Emitted when no frames have arrived on a still-advertised stream for at least the configured timeout (probe W7a: transport up, media stalled).

QualityReportingSignalRestored

Emitted when frames resume after a signal-lost period.

QualityReportingSilenceDetected

Emitted when a stream has been silent for at least min_silence_ms.

QualityReportingSilenceEnded

Emitted when signal returns after silence (min_clear_ms of audio).

QualityReportingTsErrors

TR 101 290 transport-stream error counters (ETR 101 290 priorities 1-3). Values are CUMULATIVE running totals since the stream started, Prometheus- counter style — a consumer differences successive reports for windowed counts / rates. Emitted at most ~1/s, and only when a counter has advanced.

RtmpStreamAccept

Accept a remote inbound stream on a connection. The StreamKeys that you supply will be used for the audio and video media within this RTMP stream. They should have the same SourceName and ProgramNumber as any other streams accepted on this connection, but should be unique across StreamId and RenditionName.

StreamSelection

StreamSourceSequencePreloaded

Server event: fires when the engine has held a source pin (pre-warmed + queued + ready). The streams list reflects the pin’s currently visible stream complement; the event re-fires whenever that complement changes so the client can wait for an expected shape (e.g. audio + video both present). The pin remains held until the client calls release_preloaded(pin).

StreamSourceSequenceStreamsChanged

Fires when the active pin’s seen-stream-key set changes — the active-pin sibling of StreamSourceSequencePreloaded. Typically fires after a paused-then-resumed upstream when the active source’s streams start flowing for the first time; without this event, downstream consumers have no signal that the active pin is now producing (the held-pin event is suppressed for the active pin).
