The problem is more likely to be that you're not using this function correctly.  Note that the "continueAfterOPTIONS()" function (and the other "continueAfter...()" functions) take a "RTSPClient*" as the first parameter.  In the current code, this parameter is not used (because we have only one "RTSPClient" object, which is a global variable "ourRTSPClient").  However, if you want to use this code in your own custom application - where the "RTSPClient" object is not a global variable (or there's more than one "RTSPClient" object) - then you will need to use this first parameter to the "continueAfter...()" functions; it will point to the "RTSPClient" object.
