syncWithAudio property
Whether to synchronize the data packet with the published audio packet. true: Synchronize the data packet with the audio packet.
false: Do not synchronize the data packet with the audio packet.
When you set the data packet to synchronize with the audio, then if the data packet delay is within the audio delay, the SDK triggers the streamMessage callback when the synchronized audio packet is played out. Do not set this parameter as true if you need the receiver to receive the data packet immediately. Agora recommends that you set this parameter to true only when you need to implement specific functions, for example lyric synchronization.
