在RTSPSession中,创建 QTSS_RoleParams    fRoleParams变量,该变量(联合体)用来赋值模块的角色参数.



(void)theModule->CallDispatch(QTSS_RTSPPreProcessor_Role, &fRoleParams);


enum { //Global QTSS_Register_Role = FOUR_CHARS_TO_INT('r', 'e', 'g', ' '), //reg //All modules get this once at startup QTSS_Initialize_Role = FOUR_CHARS_TO_INT('i', 'n', 'i', 't'), //init //Gets called once, later on in the startup process QTSS_Shutdown_Role = FOUR_CHARS_TO_INT('s', 'h', 'u', 't'), //shut //Gets called once at shutdown QTSS_ErrorLog_Role = FOUR_CHARS_TO_INT('e', 'l', 'o', 'g'), //elog //This gets called when the server wants to log an error.

模块的参数:参数采用联合体,所有需要参数的地方只需要创建QTSS_RoleParams对象即可. typedef union { QTSS_Register_Params regParams; QTSS_Initialize_Params initParams; QTSS_ErrorLog_Params errorParams; QTSS_StateChange_Params stateChangeParams; QTSS_Filter_Params rtspFilterParams; QTSS_IncomingData_Params rtspIncomingDataParams; QTSS_StandardRTSP_Params rtspRouteParams; QTSS_RTSPAuth_Params rtspAthnParams; QTSS_StandardRTSP_Params rtspAuthParams; QTSS_StandardRTSP_Params rtspPreProcessorParams; QTSS_StandardRTSP_Params rtspRequestParams; QTSS_StandardRTSP_Params rtspPostProcessorParams; QTSS_RTSPSession_Params rtspSessionClosingParams; QTSS_RTPSendPackets_Params rtpSendPacketsParams; QTSS_ClientSessionClosing_Params clientSessionClosingParams; QTSS_RTCPProcess_Params rtcpProcessParams; QTSS_OpenFile_Params openFilePreProcessParams; QTSS_OpenFile_Params openFileParams; QTSS_AdviseFile_Params adviseFileParams; QTSS_ReadFile_Params readFileParams; QTSS_CloseFile_Params closeFileParams; QTSS_RequestEventFile_Params reqEventFileParams; Easy_StreamInfo_Params easyStreamInfoParams; QTSS_GetAssociatedCMS_Params GetAssociatedCMSParams; QTSS_JudgeStreamID_Params JudgeStreamIDParams; Easy_GetDeviceStream_Params easyGetDeviceStreamParams; QTSS_RelayingData_Params rtspRelayingDataParams; } QTSS_RoleParams, *QTSS_RoleParamPtr; typedef struct { QTSS_RTSPSessionObject inRTSPSession; QTSS_RTSPRequestObject inRTSPRequest; QTSS_RTSPHeaderObject inRTSPHeaders; QTSS_ClientSessionObject inClientSession; } QTSS_StandardRTSP_Params;
