1. Each RTMP output stream will have its own buffer. The total buffer size increases with the number of RTMP output connections.
2. If the client’s total disconnection time exceeds the output buffer size, excess packets will be discarded. The maximum accumulated delay will be equal to the output buffer size. There will be momentary loss of video when packets get discarded. Reducing the buffer size needs to be balanced with the maximum total disconnection time and the tolerable/observable video loss.
