Hi Liu, Thanks for submitting this issue. This has been noticed in the past. This is caused because of buffering in the RTSP client (VLC for example). VLC has options to decrease the buffer so will leg much less... Hope this helps, Rene

This is a problem of the WiFi throughput; that's limited to 1MB/s or so.
I made a new RTSP streamer. Currently in develop brach. Maybe this fixes your problem
