audioBreakRate

nonatomic, assign double audioBreakRate

Audio break count, break count during the callback cycle (Available since 1.17.0)

mos

nonatomic, assign double mos

The audio quality of the playing stream determined by the audio MOS (Mean Opinion Score) measurement method, value range [-1, 5], where -1 means unknown, [0, 5] means valid score, the higher the score, the better the audio quality. For the subjective perception corresponding to the MOS value, please refer to https://docs.zegocloud.com/article/3720#4_4 (Available since 2.16.0)

rtt

nonatomic, assign int rtt

Server to local delay, in milliseconds

packetLostRate

nonatomic, assign double packetLostRate

Packet loss rate, in percentage, 0.0 ~ 1.0

peerToPeerDelay

nonatomic, assign int peerToPeerDelay

Delay from peer to peer, in milliseconds

peerToPeerPacketLostRate

nonatomic, assign double peerToPeerPacketLostRate

Packet loss rate from peer to peer, in percentage, 0.0 ~ 1.0

level

nonatomic, assign ZegoStreamQualityLevel level

Published stream quality level

delay

nonatomic, assign int delay

Delay after the data is received by the local end, in milliseconds

avTimestampDiff

nonatomic, assign int avTimestampDiff

The difference between the video timestamp and the audio timestamp, used to reflect the synchronization of audio and video, in milliseconds. This value is less than 0 means the number of milliseconds that the video leads the audio, greater than 0 means the number of milliseconds that the video lags the audio, and 0 means no difference. When the absolute value is less than 200, it can basically be regarded as synchronized audio and video, when the absolute value is greater than 200 for 10 consecutive seconds, it can be regarded as abnormal (Available since 1.19.0)

isHardwareDecode

nonatomic, assign BOOL isHardwareDecode

Whether to enable hardware decoding

videoCodecID

nonatomic, assign ZegoVideoCodecID videoCodecID

videoRecvBytes

nonatomic, assign double videoRecvBytes

Number of video bytes received
