  • Onvif开发之服务端成功对接Rtsp视频流篇

    前面篇介绍onvif服务端的发现功能，继续在之前的代码基础上完成一个RTSP流的工作，也就是客户端通过ONVIF协议来预览设备端
    在这个之前必须确定几个简单的条件
    1 设备端能被发现
    2 设备端支持RTSP协议，并且能够通过VLC进行正常的预览


    通过onvif协议设备需要做的几个基本事情：
    1  __tds__GetCapabilities获取设备能力
    2  __trt__GetProfiles获取设备的配置信息
    3  获取前段设备的视频编码和视频源的一些基本需要的信息
    4 __trt__GetStreamUri后去设备的URi，通过RTSP获取视频流

    接口函数有了，实现的时候当然也需要注意匹配，需要把设备的一些主要信息对应匹配到Onvif协议中，下面一个函数一个函数的具体实现如下，在需要注意的地方我都加上了对应的注释，如果还有不清楚的地方可以留言，我会尽量尽我所知道的告诉大家
    1 __tds__GetCapabilities，此函数是获取设备端的能力的函数，在这里需要预览，所以基本的media和device的一些基本信息是需要填写的

        (4)__trt__GetVideoSourceConfigurations需要填写的一些基本信息

    1. trt__GetVideoSourceConfigurationsResponse->Configurations[0].UseCount = 1;  
    2. trt__GetVideoSourceConfigurationsResponse->Configurations[0].Name = (char*)soap_malloc(soap, sizeof(char) * MAX_PROF_TOKEN);  
    3. memset(trt__GetVideoSourceConfigurationsResponse->Configurations[0].Name, '', sizeof(char) * MAX_PROF_TOKEN);

    7. memset(trt__GetVideoSourceConfigurationsResponse->Configurations[0].token, '', sizeof(char) * MAX_PROF_TOKEN);  
    8. strcpy(trt__GetVideoSourceConfigurationsResponse->Configurations[0].token, "test_vstoken");  
    9.   
    10. trt__GetVideoSourceConfigurationsResponse->Configurations[0].SourceToken = (char*)soap_malloc(soap, sizeof(char) * MAX_PROF_TOKEN);  
    11. memset(trt__GetVideoSourceConfigurationsResponse->Configurations[0].SourceToken, '', sizeof(char) * MAX_PROF_TOKEN);  
    12. strcpy(trt__GetVideoSourceConfigurationsResponse->Configurations[0].SourceToken, "test_vstoken");  
    13.   
    14. trt__GetVideoSourceConfigurationsResponse->Configurations[0].Bounds = (struct tt__IntRectangle *)soap_malloc(soap, sizeof(struct tt__IntRectangle));  
    15. memset(trt__GetVideoSourceConfigurationsResponse->Configurations[0].Bounds, 0, sizeof(struct tt__IntRectangle));  
    16. trt__GetVideoSourceConfigurationsResponse->Configurations[0].Bounds->x      = 0;  
    17. trt__GetVideoSourceConfigurationsResponse->Configurations[0].Bounds->y      = 0;  
    18. trt__GetVideoSourceConfigurationsResponse->Configurations[0].Bounds->width  = 1280;  
    19. trt__GetVideoSourceConfigurationsResponse->Configurations[0].Bounds->height = 720;  

    这里里面本来都是一些个不相同的，通过对应不同的Token值来获取不同的视频源以及视频编码的一些信息的，因为这里我只是一个简单的测试，所以都是对单一的视频码流填写的相关信息，可能大家看到很多地方类似的，但是当不同的token值过来的时候，需要对应填写不同的相关信息的， 每次获取的时候都需要对应的判断token值是否正确，我这里都作了一些简化，在实际开发的时候都需要填充进去

    5 __trt__GetStreamUri后去设备的URi，通过RTSP获取视频流
     

    [cpp] view plain copy

    1. trt__GetStreamUriResponse->MediaUri = (struct tt__MediaUri *)soap_malloc(soap, sizeof(struct tt__MediaUri));  
    2. memset(trt__GetStreamUriResponse->MediaUri, 0, sizeof(struct tt__MediaUri));  
    3.   
    4. trt__GetStreamUriResponse->MediaUri->Uri = (char *)soap_malloc(soap, sizeof(char) * MAX_64_LEN);  
    5. memset(trt__GetStreamUriResponse->MediaUri->Uri, '', sizeof(char) * MAX_64_LEN);  
    6. //根据各个设备的rtsp协议的uri不同填写对应的值  
    7. strncpy(trt__GetStreamUriResponse->MediaUri->Uri, "rtsp://192.168.12.135:554/livestream", MAX_64_LEN);  
    8. trt__GetStreamUriResponse->MediaUri->InvalidAfterConnect = (enum xsd__boolean)0;  
    9. trt__GetStreamUriResponse->MediaUri->InvalidAfterReboot  = (enum xsd__boolean)0;  
    10. //超时时间  
    11. trt__GetStreamUriResponse->MediaUri->Timeout = 200;  

    设备端通过Onvif协议来实现RTSP预览的代码已经基本写完，现在可以看看效果，首先确定设备端能够通过vlc正确预览图像， 也就是说设备端需要支持RTSP协议，

    可能通过Live555来实现。然后就可以通过onvif的工具 Onvif  Deviece Manager 来查看效果了！

     先看看Live Video的效果

      z

    再看看Video Stream的效果图

     最后看看token的一些显示的基本信息

    里面因为是自己的一些token和name信息，所以我就打了码，这是都是可以根据自己的设备自己来定的，所以对对接视频没有响，只要在请求的时候对应自己的设备的能力值获取的时候对应起来就可以的！onvif设备端对接视频流也就完成！

     

    这个过程中还是有很多不不懂的地方，可能上面的开发过程很多不够完善的地方，如果有懂的更多这方面知识的开发者，
    希望能指出我的不足或者提出自己的观点，大家相互促进学习。
