static void	continueAfterDESCRIBE (RTSPClient rtspClient, int resultCode, char resultString)
	Called after rtsp DESCRIBE command gets a reply.

static void	continueAfterGET_PARAMETER (RTSPClient rtspClient, int resultCode, char resultString)
	Used by pingGET_PARAMETER: a dummy callback to GET_PARAMETER.

static void	subsessionAfterPlaying (void *clientData)
	Called when a stream's subsession (e.g., audio or video substream) ends.

static void	subsessionByeHandler (void *clientData)
	Called when a RTCP "BYE" is received for a subsession.

static void	streamTimerHandler (void *clientData)
	Called at the end of a stream's expected duration (if the stream has not already signaled its end using a RTCP "BYE")

static void	setupNextSubsession (RTSPClient *rtspClient)
	Used to iterate through each stream's 'subsessions', setting up each one.

static void	shutdownStream (RTSPClient *rtspClient, int exitCode=1)
	Used to shut down and close a stream (including its "RTSPClient" object):

static void	pingGetParameter (void *clientData)
