Onvif開發之服務端成功對接Rtsp視頻流篇

本文轉載自   查看原文   2017-03-23 14:13   4047    onvif

前面篇介紹onvif服務端的發現功能，繼續在之前的代碼基礎上完成一個RTSP流的工作，也就是客戶端通過ONVIF協議來預覽設備端
在這個之前必須確定幾個簡單的條件
1 設備端能被發現
2 設備端支持RTSP協議，並且能夠通過VLC進行正常的預覽


通過onvif協議設備需要做的幾個基本事情：
1  __tds__GetCapabilities獲取設備能力
2  __trt__GetProfiles獲取設備的配置信息
3  獲取前段設備的視頻編碼和視頻源的一些基本需要的信息
4 __trt__GetStreamUri后去設備的URi，通過RTSP獲取視頻流

接口函數有了，實現的時候當然也需要注意匹配，需要把設備的一些主要信息對應匹配到Onvif協議中，下面一個函數一個函數的具體實現如下，在需要注意的地方我都加上了對應的注釋，如果還有不清楚的地方可以留言，我會盡量盡我所知道的告訴大家
1 __tds__GetCapabilities，此函數是獲取設備端的能力的函數，在這里需要預覽，所以基本的media和device的一些基本信息是需要填寫的

  13.   
  14. trt__GetVideoSourceConfigurationResponse->Configuration->Bounds = (struct tt__IntRectangle *)soap_malloc(soap, sizeof(struct tt__IntRectangle));

    (4)__trt__GetVideoSourceConfigurations需要填寫的一些基本信息

 

[cpp]  view plain  copy
 
 在CODE上查看代碼片派生到我的代碼片
  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, '\0', sizeof(char) * MAX_PROF_TOKEN);  
  4. strcpy(trt__GetVideoSourceConfigurationsResponse->Configurations[0].Name, "test_vsname");  
  5.   
  6. trt__GetVideoSourceConfigurationsResponse->Configurations[0].token = (char*)soap_malloc(soap, sizeof(char) * MAX_PROF_TOKEN);  
  7. memset(trt__GetVideoSourceConfigurationsResponse->Configurations[0].token, '\0', 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, '\0', 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;  

這里里面本來都是一些個不相同的，通過對應不同的Token值來獲取不同的視頻源以及視頻編碼的一些信息的，因為這里我只是一個簡單的測試，所以都是對單一的視頻碼流填寫的相關信息，可能大家看到很多地方類似的，但是當不同的token值過來的時候，需要對應填寫不同的相關信息的， 每次獲取的時候都需要對應的判斷token值是否正確，我這里都作了一些簡化，在實際開發的時候都需要填充進去

5 __trt__GetStreamUri后去設備的URi，通過RTSP獲取視頻流
 

[cpp]  view plain  copy
 
 在CODE上查看代碼片派生到我的代碼片
  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, '\0', sizeof(char) * MAX_64_LEN);  
  6. //根據各個設備的rtsp協議的uri不同填寫對應的值  
  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. //超時時間  
  11. trt__GetStreamUriResponse->MediaUri->Timeout = 200;  

 

設備端通過Onvif協議來實現RTSP預覽的代碼已經基本寫完，現在可以看看效果，首先確定設備端能夠通過vlc正確預覽圖像， 也就是說設備端需要支持RTSP協議，

可能通過Live555來實現。然后就可以通過onvif的工具 Onvif  Deviece Manager 來查看效果了！

 先看看Live Video的效果

  z

再看看Video Stream的效果圖

 最后看看token的一些顯示的基本信息

里面因為是自己的一些token和name信息，所以我就打了碼，這是都是可以根據自己的設備自己來定的，所以對對接視頻沒有響，只要在請求的時候對應自己的設備的能力值獲取的時候對應起來就可以的！onvif設備端對接視頻流也就完成！

 

這個過程中還是有很多不不懂的地方，可能上面的開發過程很多不夠完善的地方，如果有懂的更多這方面知識的開發者，
希望能指出我的不足或者提出自己的觀點，大家相互促進學習。
