EasyNVRRTSP摄像机转HLS直播服务器中使用Onvif协议控制预置位

EasyNVR支持预置位控制&＃xff0c;包括转到指定预置位&＃xff0c;设置指定预置位&＃xff0c;删除指定预置位

预置位在安防领域有较为普遍的应用&＃xff0c;可以进行很多既定位置的跳转&＃xff0c;很方便

之前我们说过如何用Onvif协议进行设备的发现&＃xff0c;探测&＃xff0c;以及云台控制等&＃xff0c;今天我们来说一下如何使用Onvif进行预置位的操作

流程

获取设备能力Capabilities

获取设备的能力&＃xff0c;并且可以获取到Media和PTZ的URI&＃xff0c;使用这两个URL可以进行流和预置位操作&＃xff0c;这里如果PTZ URI获取不到意味着这个设备无法支持预置位控制

_tds__GetCapabilities* capabilities &＃61; soap_new__tds__GetCapabilities(proxyDevice, -1);
tt__CapabilityCategory* category &＃61; new tt__CapabilityCategory;
capabilities->Category &＃61; category;
*(capabilities->Category) &＃61; tt__CapabilityCategory__All;
_tds__GetCapabilitiesResponse* response &＃61; soap_new__tds__GetCapabilitiesResponse(proxyDevice, -1);
if (SOAP_OK &＃61;&＃61; proxyDevice->GetCapabilities(capabilities, response))
{if (response->Capabilities){//Media URI: response->Capabilities->Media->XAddr;//PTZ URI: response->Capabilities->PTZ->XAddr;}
}

获取Media Profile

_trt__GetProfiles* getProfiles &＃61; soap_new__trt__GetProfiles(proxyMedia, -1);
_trt__GetProfilesResponse* response &＃61; soap_new__trt__GetProfilesResponse(proxyMedia, -1);
if (SOAP_OK &＃61;&＃61; proxyMedia->GetProfiles(getProfiles, response))
{int size &＃61; response->__sizeProfiles;for (int i &＃61; 0; i <size; &＃43;&＃43;i){if (response->Profiles[i]){//Media Profile Token: response->Profiles[i]->token;//一般设备包含多个Profile Token&＃xff0c;包含主码流、子码流、第三码流}}
}

预置位控制

bool result &＃61; false;PTZBindingProxy* ptzProxy &＃61; new PTZBindingProxy;ptzProxy->soap_endpoint &＃61; ptzUrl.c_str();if (!security(ptzProxy, username, password)){delete ptzProxy;return result;}char presetToken[8];itoa(index, presetToken, 10);if (command &＃61;&＃61; PRESET_GOTO){_tptz__GotoPreset* preset &＃61; soap_new__tptz__GotoPreset(ptzProxy, -1);_tptz__GotoPresetResponse* response &＃61; soap_new__tptz__GotoPresetResponse(ptzProxy, -1);preset->ProfileToken &＃61; const_cast<char*>(profile.c_str());preset->PresetToken &＃61; presetToken;if (SOAP_OK &＃61;&＃61; ptzProxy->GotoPreset(preset, response))result &＃61; true;if (response)soap_delete__tptz__GotoPresetResponse(ptzProxy, response);if (preset)soap_delete__tptz__GotoPreset(ptzProxy, preset);}else if (command &＃61;&＃61; PRESET_SET){_tptz__SetPreset* preset &＃61; soap_new__tptz__SetPreset(ptzProxy, -1);_tptz__SetPresetResponse* response &＃61; soap_new__tptz__SetPresetResponse(ptzProxy, -1);preset->ProfileToken &＃61; const_cast<char*>(profile.c_str());preset->PresetToken &＃61; presetToken;if (SOAP_OK &＃61;&＃61; ptzProxy->SetPreset(preset, response))result &＃61; true;if (response)soap_delete__tptz__SetPresetResponse(ptzProxy, response);if (preset)soap_delete__tptz__SetPreset(ptzProxy, preset);}else if (command &＃61;&＃61; PRESET_REMOVE){_tptz__RemovePreset* preset &＃61; soap_new__tptz__RemovePreset(ptzProxy, -1);_tptz__RemovePresetResponse* response &＃61; soap_new__tptz__RemovePresetResponse(ptzProxy, -1);preset->ProfileToken &＃61; const_cast<char*>(profile.c_str());preset->PresetToken &＃61; presetToken;if (SOAP_OK &＃61;&＃61; ptzProxy->RemovePreset(preset, response))result &＃61; true;if (response)soap_delete__tptz__RemovePresetResponse(ptzProxy, response);if (preset)soap_delete__tptz__RemovePreset(ptzProxy, preset);}delete ptzProxy;return result;
