soap实现ONVIF协议PTZControl的AbsoluteMove失败

请教各位大神，使用gSoap工具生成的ONVIF协议的C代码，想实现摄像头的AbsoluteMove，我用ONVIF Device Test Tool工具测试，我的摄像头是支持AbsoluteMove的，但是我调用soap_call___tptz__AbsoluteMove方法时，返回值永远是12，摄像头也没有动，
有大神知道是什么原因吗？
这是我的代码

struct _tptz__AbsoluteMove *AbsoluteMove;

	struct _tptz__AbsoluteMoveResponse *AbsoluteMoveResponse;

	AbsoluteMove = (_tptz__AbsoluteMove*)soap_malloc(soap, sizeof(struct _tptz__AbsoluteMove));

	AbsoluteMoveResponse = (_tptz__AbsoluteMoveResponse*)soap_malloc(soap, sizeof(struct _tptz__AbsoluteMoveResponse));

	soap_default__tptz__AbsoluteMove(soap, AbsoluteMove);//内存清零

	soap_default__tptz__AbsoluteMoveResponse(soap, AbsoluteMoveResponse);



	AbsoluteMove->ProfileToken = trt__GetProfilesResponse.Profiles->token;

	AbsoluteMove->Position = (tt__PTZVector*)soap_malloc(soap, sizeof(struct tt__PTZVector));

	AbsoluteMove->Position->PanTilt = (tt__Vector2D*)soap_malloc(soap, sizeof(struct tt__Vector2D));

	AbsoluteMove->Position->PanTilt->x = -0.9798;//P这里是随便写的几个数

	AbsoluteMove->Position->PanTilt->y = 0.6768;//T

	AbsoluteMove->Position->PanTilt->space = (char*)soap_malloc(soap, 128);

	strcpy(AbsoluteMove->Position->PanTilt->space, "http://www.onvif.org/ver10/schema");

	AbsoluteMove->Speed = (tt__PTZSpeed*)soap_malloc(soap, sizeof(struct tt__PTZSpeed));

	AbsoluteMove->Speed->PanTilt = (tt__Vector2D*)soap_malloc(soap, sizeof(struct tt__Vector2D));;

	AbsoluteMove->Speed->PanTilt->x = 1.0;//P方向转速

	AbsoluteMove->Speed->PanTilt->y = 1.0;//T方向转速

	AbsoluteMove->Speed->PanTilt->space = (char*)soap_malloc(soap, 128);

	strcpy(AbsoluteMove->Speed->PanTilt->space, "http://www.onvif.org/ver10/schema");



	AbsoluteMove->Position->Zoom = (tt__Vector1D*)soap_malloc(soap, sizeof(struct tt__Vector1D));

	AbsoluteMove->Position->Zoom->x = 0.7646;//Z

	AbsoluteMove->Position->Zoom->space = (char*)soap_malloc(soap, 128);

	strcpy(AbsoluteMove->Position->Zoom->space, "http://www.onvif.org/ver10/schema");

	AbsoluteMove->Speed->Zoom = (tt__Vector1D*)soap_malloc(soap, sizeof(struct tt__Vector1D));;

	AbsoluteMove->Speed->Zoom->x = 1.0;//Z缩放速度

	AbsoluteMove->Speed->Zoom->space = (char*)soap_malloc(soap, 128);

	strcpy(AbsoluteMove->Speed->Zoom->space, "http://www.onvif.org/ver10/schema");



	soap_wsse_add_UsernameTokenDigest(soap, "", UserName.c_str(), PassWord.c_str());

	int ret = soap_call___tptz__AbsoluteMove(soap, capa_resp.Capabilities->PTZ->XAddr, NULL, AbsoluteMove, AbsoluteMoveResponse);

	if (ret == SOAP_OK)

	{

		printf("AbsoluteMove----OK\n");

	}
