question
When using Wireshark to capture packets, it is often found that there are many problems with Unknown packets.
During the rtmp interaction process, Set chunk Size 60000
analyze
Open the wireshark settings and find the maximum packet size setting in the RTMPT settings. The default value is 32768, and the default RTMPT protocol configures the function of reassembling RTMPT from multiple TCP streams (should consider the HTTP-based transmission method).
Wireshark -->preferences --> Protocol --> rtmpt
So the packet size here needs to be configured larger. The chunk size in the captured packet is 60000, so the configuration is larger. I chose 1048576 here.
