Comment:

 Maybe the following command line helps you understanding the issue -
 option placement does matter - better:
 {{{
 $ ffmpeg -rtsp_transport udp -i rtsp://192.168.1.1/554 -rtsp_transport tcp
 rtsp://192.168.1.2/554
 }}}

 Iiuc, unused format and protocol options - contrary to encoder options -
 do not trigger a warning.
 {{{
 $ ffmpeg -i fate-suite/lena.pnm -rtsp_transport tcp -user_agent foo -key
 bar -write_id3v2 1 -f null -
