Constants

OTPublisherVideoEventNone

No notable video event or quality degradation. Default or unknown reason.

Declared In OTVideoEventReason.h.

OTPublisherVideoEventPublisherPropertyChanged

The video event was caused by this publisher changing the value for OTPublisherKit.publishVideo.

Declared In OTVideoEventReason.h.

OTPublisherVideoEventQualityChanged

The video event was caused by a change in the network congestion level. The [OTPublisherKitDelegate publisherVideoDisabled:reason:] message is sent. When conditions improve, the video stream resumes, and the [OTPublisherKitDelegate publisherVideoEnabled:reason:] message is sent.

Declared In OTVideoEventReason.h.

OTPublisherVideoEventQualityDegradationBandwidth

Quality degradation due to insufficient network bandwidth.

Declared In OTVideoEventReason.h.

OTPublisherVideoEventQualityDegradationCPU

Quality degradation caused by CPU limitations on the client device.

Declared In OTVideoEventReason.h.

OTPublisherVideoEventQualityDegradationOther

Quality degradation caused by other reasons.

Declared In OTVideoEventReason.h.

OTPublisherVideoEventCodecChange

The video codec for the stream has changed.

Declared In OTVideoEventReason.h.

OTPublisherVideoEventResolutionChange

Change in video resolution or number of layers. This can occur due to bitrate constraints, encoder adaptation, camera source changes (e.g., switching cameras or changing input resolution), or configuration changes. Does not always imply quality degradation.
