Linux下onvif客戶端獲取h265 IPC攝像頭的RTSP地址

1、 設備搜索，去獲取webserver 的地址 ，目的是在獲取能力提供服務地址，demo：https://www.cnblogs.com/croxd/p/10683429.html

2、 GetCapabilities獲取能力，目的是在GetProfiles時提供媒體地址，demo：https://www.cnblogs.com/croxd/p/10683503.html，

如果GetCapabilities獲取能力失敗，soap error 4 或者 52的話，可以參考：https://www.cnblogs.com/croxd/p/10684712.html

    char sercer_addr[] = "http://172.168.0.211/onvif/device_service";//設備搜索獲取到的地址
    struct SOAP_ENV__Header header;
    struct soap* soap = ONVIF_Initsoap(&header, NULL, NULL, 5);
    struct _tds__GetCapabilities *req;
    struct _tds__GetCapabilitiesResponse *Response;

    req->__sizeCategory = 1;
    req->Category = (enum tt__CapabilityCategory *)soap_malloc(soap, sizeof(int));
    *(req->Category) = (enum tt__CapabilityCategory)5; //5表示：tt__CapabilityCategory__Media

    ONVIF_SetAuthInfo(soap,"admin","123456");  //鑒權，輸入攝像頭的用戶名、密碼
    ret = soap_call___tds__GetCapabilities(soap, sercer_addr, NULL,req, Response);

3 、GetServices獲取多個媒體地址 demo：https://www.cnblogs.com/croxd/p/10683576.html

要是在獲取GetProfiles時，用第二步的媒體地址不支持h265，那麼你就需要調用這個介面。在這個介面的tds__GetServicesResponse結構體中可以獲取兩個媒體地址  。要是之前沒有安裝h265的gsoap環境，這邊也是只能獲取一個媒體地址，安裝h265的環境請查看上一篇的文章 ：Linux下onvi支持h265環境的的搭建 

    char secvre_addr[] = "http://172.168.0.211/onvif/device_service"; //設備搜索獲取得到的服務地址
    struct SOAP_ENV__Header header;
    struct _tds__GetServices *tds__GetServices;
    struct _tds__GetServicesResponse *tds__GetServicesResponse;
 
    struct soap* soap = ONVIF_Initsoap(&header, NULL, NULL, 5);
    
    tds__GetServices->IncludeCapability = 0;
 
    ONVIF_SetAuthInfo(soap,"admin","123456");  //鑒權
    soap_call___tds__GetServices(soap,secvre_addr,NULL, tds__GetServices, tds__GetServicesResponse);

4、GetProfiles 獲取媒體信息文件 demo：https://www.cnblogs.com/croxd/p/10683598.html

從tr2__GetProfilesResponse結構體獲取媒體信息文件，soap_call___tr2__GetProfiles介面是安裝h265的環境時，gsoap框架所生成的介面。

    char media_addr2[] = "http://172.168.0.211/onvif/media2_service"; //GetServices得到的地址
    struct SOAP_ENV__Header header;  
    struct soap* soap = ONVIF_Initsoap(&header, NULL, NULL, 5);
 
    struct _tr2__GetProfiles tr2__GetProfiles;
    struct _tr2__GetProfilesResponse tr2__GetProfilesResponse;
    
    tr2__GetProfiles.__sizeType = 1;
    tr2__GetProfiles.Token = NULL;  
    tr2__GetProfiles.Type = NULL;
    ONVIF_SetAuthInfo(soap,"admin","123456");  //鑒權
    soap_call___tr2__GetProfiles(soap, media_addr2, NULL, &tr2__GetProfiles, &tr2__GetProfilesResponse);   

5、 GetStreamUri 獲取RTSP地址 demo：https://www.cnblogs.com/croxd/p/10683616.html

從tr2__GetStreamUriResponse結構體中獲取h265的RTSP地址，soap_call___tr2__GetStreamUri介面是安裝h265的環境時，gsoap框架所生成的介面。

    char media_addr2[] = "http://172.168.0.211/onvif/media2_service"; //GetServices得到的地址
    char taken[] = "Profile000";   //get_profiles獲取
    struct SOAP_ENV__Header header;
    
    struct soap* soap = ONVIF_Initsoap(&header, NULL, NULL, 5);
    struct _tr2__GetStreamUri tr2__GetStreamUri;
    struct _tr2__GetStreamUriResponse tr2__GetStreamUriResponse;
    tr2__GetStreamUri.Protocol = (char *)soap_malloc(soap, 128*sizeof(char));//
    if (NULL == tr2__GetStreamUri.Protocol){
        printf("soap_malloc is error\n");
        ret = -1;
    }

    tr2__GetStreamUri.ProfileToken = (char *)soap_malloc(soap, 128*sizeof(char ));//
    if (NULL == tr2__GetStreamUri.ProfileToken){
        printf("soap_malloc is error\n");
        ret = -1;
    }

    strcpy(tr2__GetStreamUri.Protocol, "tcp");
    strcpy(tr2__GetStreamUri.ProfileToken, taken);
    ONVIF_SetAuthInfo(soap,"admin","123456");  //鑒權
    soap_call___tr2__GetStreamUri(soap, media_addr2, NULL, &tr2__GetStreamUri, &tr2__GetStreamUriResponse);
