Linux下onvif客户端获取h265 IPC摄像头的RTSP地址

1、 设备搜索，去获取webserver 的地址 ，目的是在获取能力提供服务地址，demo：https://www.cnblogs.com/croxd/p/10683429.html

2、 GetCapabilities获取能力，目的是在GetProfiles时提供媒体地址，demo：https://www.cnblogs.com/croxd/p/10683503.html，

如果GetCapabilities获取能力失败，soap error 4 或者 52的话，可以参考：https://www.cnblogs.com/croxd/p/10684712.html

    char sercer_addr[] = "http://172.168.0.211/onvif/device_service";//设备搜索获取到的地址
    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");  //鉴权，输入摄像头的用户名、密码
    ret = soap_call___tds__GetCapabilities(soap, sercer_addr, NULL,req, Response);

3 、GetServices获取多个媒体地址 demo：https://www.cnblogs.com/croxd/p/10683576.html

要是在获取GetProfiles时，用第二步的媒体地址不支持h265，那么你就需要调用这个接口。在这个接口的tds__GetServicesResponse结构体中可以获取两个媒体地址  。要是之前没有安装h265的gsoap环境，这边也是只能获取一个媒体地址，安装h265的环境请查看上一篇的文章 ：Linux下onvi支持h265环境的的搭建 

    char secvre_addr[] = "http://172.168.0.211/onvif/device_service"; //设备搜索获取得到的服务地址
    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");  //鉴权
    soap_call___tds__GetServices(soap,secvre_addr,NULL, tds__GetServices, tds__GetServicesResponse);

4、GetProfiles 获取媒体信息文件 demo：https://www.cnblogs.com/croxd/p/10683598.html

从tr2__GetProfilesResponse结构体获取媒体信息文件，soap_call___tr2__GetProfiles接口是安装h265的环境时，gsoap框架所生成的接口。

    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");  //鉴权
    soap_call___tr2__GetProfiles(soap, media_addr2, NULL, &tr2__GetProfiles, &tr2__GetProfilesResponse);   

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

从tr2__GetStreamUriResponse结构体中获取h265的RTSP地址，soap_call___tr2__GetStreamUri接口是安装h265的环境时，gsoap框架所生成的接口。

    char media_addr2[] = "http://172.168.0.211/onvif/media2_service"; //GetServices得到的地址
    char taken[] = "Profile000";   //get_profiles获取
    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
");
        ret = -1;
    }

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

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