default to the Web side as long as there is a push stream on the

note:

Remote user (communication scenario)/anchor (live scenario) is called back from

the current channel.A remote user/anchor has left the channel (or dropped the line).

There are two reasons for users to leave the channel, namely normal departure and

time-out:When leaving normally, the remote user/anchor will send a message like

"goodbye". After receiving this message, determine if the user left the channel.

The basis of timeout dropout is that within a certain period of time

(live broadcast scene has a slight delay), if the user does not receive any

packet from the other side, it will be judged as the other side dropout.

False positives are possible when the network is poor. We recommend using the

Agora Real-time messaging SDK for reliable drop detection.
