Onvif 获取指定通道的流媒体地址

GetStreamUri函数可以获取流媒体地址。
代码如下：
void UserGetUri(const char* xAddr)
{
　　int result=0 ;
　　struct soap *soap = soap_new();
　　struct _trt__GetStreamUri trt__GetStreamUri ;
　　struct _trt__GetStreamUriResponse trt__GetStreamUriResponse;
　　printf(" ---------------Getting Uri---------------- ");

　　trt__GetStreamUri.StreamSetup = (struct tt__StreamSetup *)soap_malloc(soap, sizeof(struct tt__StreamSetup));
　　trt__GetStreamUri.StreamSetup->__any = NULL;
　　trt__GetStreamUri.StreamSetup->__anyAttribute = NULL;
　　trt__GetStreamUri.StreamSetup->__size = 1;
　　trt__GetStreamUri.StreamSetup->Stream = tt__StreamType__RTP_Unicast;
　　trt__GetStreamUri.StreamSetup->Transport = (struct tt__Transport *)soap_malloc(soap,sizeof(struct tt__Transport));
　　trt__GetStreamUri.StreamSetup->Transport->Protocol = tt__TransportProtocol__UDP;
　　trt__GetStreamUri.StreamSetup->Transport->Tunnel = NULL;
　　trt__GetStreamUri.ProfileToken = soap_malloc(soap, 1024);
　　strcpy(trt__GetStreamUri.ProfileToken , "Token_000"); //指明哪一通道的流媒体地址
　　soap_call___trt__GetStreamUri(soap, xAddr, NULL, &trt__GetStreamUri, &trt__GetStreamUriResponse);

　　if (soap->error)
　　{
　　　　printf("soap error: %d, %s, %s ", soap->error, *soap_faultcode(soap), *soap_faultstring(soap));
　　　　result = soap->error;

　　}

　　else
　　{
　　　　printf("!!!!NOTE: RTSP Addr Get Done is :%s ",trt__GetStreamUriResponse.MediaUri->Uri);
　　}

}
