-4 output a '.mp4'-format file (to 'stdout')
-a play only the audio stream
-A <codec-number> specify the static RTP payload format number of the audio codec to request from the server ("playSIP" only)

-M <MIME-subtype> specify the MIME subtype of a dynamic RTP payload format for the audio codec to request from the server ("playSIP" only)
-d <duration> specify an explicit duration
-D <maximum-inter-packet-gap> specify a maximum period of inactivity to wait before exiting
-f <frame-rate> specify the video frame rate (used only with "-q", "-4", or "-i")
-F <fileName-prefix> specify a prefix for each output file name
-h <height> specify the video image height (used only with "-q", "-4", or "-i")
-H output a QuickTime 'hint track' for each audio/video track (used only with "-q" or "-4")

-l try to compensate for packet losses (used only with "-q", "-4", or "-i")
-m output each incoming frame into a separate file
-n be notified when RTP data packets start arriving
-o request the server's command options, without sending "DESCRIBE" ("openRTSP" only)

-p <startingPortNumber> specify the client port number(s)
-Q output 'QOS' statistics about the data stream (when the program exits)
-q output a QuickTime '.mov'-format file (to 'stdout')
-r play the RTP streams, but don't receive them ourself
-s <initial-seek-time> request that the server seek to the specified time (in seconds) before streaming
-S <byte-offset> assume a simple RTP payload format (skipping over a special header of the specified size)
-t stream RTP/RTCP data over TCP, rather than (the usual) UDP. ("openRTSP" only)
-T <http-port-number> like "-t", except using RTSP-over-HTTP tunneling. ("openRTSP" only)
-u <username> <password> specify a user name and password for digest authentication
