| onVideoSizeChanged | when the video size or rotation information of a specified remote user changes |
| onRemoteVideoStateChanged | when the remote video stream state changes |
| onLocalPublishFallbackToAudioOnly | when the published media stream falls back to an audio-only stream due to poor network conditions or switches back to video stream after the network conditions improve |

| onLocalVideoStat | Reports the statistics of the uploading local video streams |
| onRemoteVideoStat | Reports the statistics of the video stream from each remote user/host.|
| onRemoteAudioTransportStats | Reports the transport-layer statistics of each remote audio stream.This callback reports the transport-layer statistics, such as the packet loss rate and time delay, once every two seconds after the local user receives an audio packet from a remote user. |
| onRemoteVideoTransportStats | Reports the transport-layer statistics of each remote video stream.This callback reports the transport-layer statistics, such as the packet loss rate and time delay, once every two seconds after the local user receives the video packet from a remote user. |

| onAudioEffectFinished | when the audio effect file playback finishes. |
| onStreamPublished | when a CDN live stream is published. |
| onStreamUnpublished | when CDN live streaming stops. |
