Answer 1

The mplayer help explain this is for HTTP:

-user-agent
Use as user agent for HTTP streaming.

If you look at mpayer source code demux_rtp.cpp you will see that there is no way to specify the user-agent string used by RTSPClient.

In order to set it you could call the live555 API of class RTSPClient:

void    setUserAgentString (char const *userAgentName)
