There are 2 possbile reasions:
- The network is unstable.
- The live stream server is unavailable.
Most of the case it is an unstable network. The MSDK log may print "sendNativeMRTCAgentVideoData error, code = 420478978" which means a timeout is happened. It is suggested to add a listener for LiveStreamStatus. Pay attention to the getPacketLoss, getPacketCacheLen and getRtt to judge the current network status.
