The Real Time Messaging Protocol (RTMP) is a proprietary protocol developed by Macromedia, now owned by Adobe, primarily used for high-performance transmission of audio, video, and data between a server and Flash player. Operating over TCP port 1935, RTMP enables low-latency streaming which contributed to Flash's dominance in web video delivery during its peak. Despite Flash's decline, RTMP remains popular in live streaming infrastructure and content delivery due to its robustness, simplicity, and widespread support.

Which one is on your host

ask the machine, not the registry

The registry says what 1935 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.

linux
ss -ltnp | grep ':1935\b'
macos
lsof -nP -iTCP:1935 -sTCP:LISTEN
windows
netstat -ano | findstr :1935

On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.

A port number is not a service. Anything may listen on 1935 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
