A lot of use cases, such as client authentication etc require passing connection parameters to the media server. When using a client such as FFmpeg, you can pass parameters to Red5 Pro for an RTMP request but not an RTSP request (currently not supported).

For ‘non-flash’ RTMP clients, Red5 Pro allows passing connections params in the connection URL only. An important thing to remember is that parameters arrive at Red5 Pro as a part of the connection URL and not the stream name. The stream name should always appear at the end of the connection URL.

Parameters need to be appended to the RTMP connection URL as a query string a shown below.

rtmp://<host>:1935/live?param1=value1&param2=value2

Passing parameters over RTSP using FFmpeg is currently not supported.
