有了前几篇的基础,现在可以正式开始onvif的实现工作,其中一项非常重要的部分就是 视频流的对接,即能够在符合onvif标准的监控客户端软件里接收到设备端NVT发来的RTSP视频流。这里,我所用的客户端软件是Onvif Device Manager v2.2。【来自http://blog.csdn.net/ghostyu】
ONVIF Profile S Specification文档描述了Device或者说DVT和Client可以使用的一种Profile,Profile这个词在计算机领域非常常见,我们可以理解成一种方案、配置、框架等。
文档里描述了如果实现VideoStream,device和client应该具备的条件,当然如果实现文档的所有条件,就可以说该设备符合Profile S
如果单纯实现VideoStream,只需完成下列命令。
1、GetProfiles 2、GetStreamUri 填充rtsp路径,例如:rtsp://192.168.1.201/petrov.m4e 3、Media Streaming using RTSP 这里使用开源的live555,完成rtsp功能 4、GetVideoEncoderConfiguration 5、GetVideoEncoderConfigurationOptions 6、GetCapabilities NVC为了获取DVT所支持的功能的命令
参考文档:
1、ONVIF Profile S Specification 描述ProfileS是什么样的一个东西,如何实现 2、Reference_of_ONVIF_Development_v1.01.02 Onvif DVT设计参考,指明了一条道路,但没有具体内容 3、ONVIF-Media-Service-Spec-v220 Onvif Media的说明介绍 4、http://www.onvif.org/onvif/ver20/util/operationIndex.html onvif几乎全部命令的详细说明,非常重要。该文档告诉我们结构体成员的意义和如何填充。Onvif开发其实就是各种结构体的填充。
一、产生onvif源码框架
1、从wsdl生成C头文件
- wsdl2h -o onvif.h -c -s -t .\typemap.dat
- http:
-
跟前一篇discovery唯一不同的是,这里多了很多wsdl文件,这次创建完整的onvif代码框架
2、从头文件生成源码框架
soapcpp2 -c onvif.h -x -I /root/onvif/gsoap-2.8/gsoap/import -I /root/onvif/gsoap-2.8/gsoap/
产生的C文件比较庞大,最大的有十几兆,大部分的内容没有复用导致。
二、创建soap运行环境
- int main(int argc, char **argv)
- {
- int m, s;
- struct soap add_soap;
- int server_udp;
- server_udp = create_server_socket_udp();
-
- pthread_t thrHello;
- pthread_t thrProbe;
-
-
- pthread_create(&thrProbe,NULL,main_Probe,server_udp);
-
- soap_init(&add_soap);
- soap_set_namespaces(&add_soap, namespaces);
-
- if (argc < 0) {
- printf("usage: %s <server_port> \n", argv[0]);
- exit(1);
- } else {
- m = soap_bind(&add_soap, NULL, 80, 100);
- if (m < 0) {
- soap_print_fault(&add_soap, stderr);
- exit(-1);
- }
- fprintf(stderr, "Socket connection successful: master socket = %d\n", m);
- for (;;) {
- s = soap_accept(&add_soap);
- if (s < 0) {
- soap_print_fault(&add_soap, stderr);
- exit(-1);
- }
- fprintf(stderr, "Socket connection successful: slave socket = %d\n", s);
- soap_serve(&add_soap);
- soap_end(&add_soap);
- }
- }
- return 0;
- }
注意,这里绑定了80端口,onvif使用的是http请求,然后附带xml,其实正常的是将onvif集成到web服务器中,普通的http请求有 web服务器处理,onvif的http请求则有soap处理。我们这里的做法也可行,只不过onvif的访问web服务器的功能是无法使用的。
三、RTSP视频对接
1、实现GetCapabilities命令
客户端发送GetCapabilities命令来得到设备端的能力,然后依据GetCapabilities返回的结果再来进行下一步操作
在__tds__GetCapabilities函数中我们只需要填充Media部分和一些必要的即可
-
- tds__GetCapabilitiesResponse->Capabilities->Media
- = (struct tt__MediaCapabilities*)soap_malloc(soap, sizeof(struct tt__MediaCapabilities));
- tds__GetCapabilitiesResponse->Capabilities->Media->XAddr
- = (char *) soap_malloc(soap, sizeof(char) * LARGE_INFO_LENGTH);
- strcpy(tds__GetCapabilitiesResponse->Capabilities->Media->XAddr, _IPv4Address);
- tds__GetCapabilitiesResponse->Capabilities->Media->StreamingCapabilities
- = (struct tt__RealTimeStreamingCapabilities*)soap_malloc(soap
- , sizeof(struct tt__RealTimeStreamingCapabilities));
- tds__GetCapabilitiesResponse->Capabilities->Media->StreamingCapabilities->RTPMulticast
- = (int *)soap_malloc(soap, sizeof(int));
- *tds__GetCapabilitiesResponse->Capabilities->Media->StreamingCapabilities->RTPMulticast
- = _false;
- tds__GetCapabilitiesResponse->Capabilities->Media->StreamingCapabilities->RTP_USCORETCP
- = (int *)soap_malloc(soap, sizeof(int));
- *tds__GetCapabilitiesResponse->Capabilities->Media->StreamingCapabilities->RTP_USCORETCP
- = _true;
- tds__GetCapabilitiesResponse->Capabilities->Media->StreamingCapabilities
- ->RTP_USCORERTSP_USCORETCP
- = (int *)soap_malloc(soap, sizeof(int));
- *tds__GetCapabilitiesResponse->Capabilities->Media->StreamingCapabilities
- ->RTP_USCORERTSP_USCORETCP
- = _true;
- tds__GetCapabilitiesResponse->Capabilities->Media->StreamingCapabilities->Extension
- = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Media->Extension = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Media->__size = 0;
- tds__GetCapabilitiesResponse->Capabilities->Media->__any = 0;
另外必要填充的还有
-
- tds__GetCapabilitiesResponse->Capabilities->Extension->DeviceIO->VideoSources = TRUE;
- tds__GetCapabilitiesResponse->Capabilities->Extension->DeviceIO->VideoOutputs = FALSE;
- tds__GetCapabilitiesResponse->Capabilities->Extension->DeviceIO->AudioSources = FALSE;
- tds__GetCapabilitiesResponse->Capabilities->Extension->DeviceIO->AudioOutputs = FALSE;
- tds__GetCapabilitiesResponse->Capabilities->Extension->DeviceIO->RelayOutputs = FALSE;
- tds__GetCapabilitiesResponse->Capabilities->Extension->DeviceIO->__size = 0;
- tds__GetCapabilitiesResponse->Capabilities->Extension->DeviceIO->__any = NULL;
-
- tds__GetCapabilitiesResponse->Capabilities->Extension->Display = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Extension->Recording = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Extension->Search = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Extension->Replay = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Extension->Receiver = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Extension->AnalyticsDevice = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Extension->Extensions = NULL;
- tds__GetCapabilitiesResponse->Capabilities->Extension->__size = 0;
- tds__GetCapabilitiesResponse->Capabilities->Extension->__any = NULL;
2、实现GetServices命令
- int __tds__GetServices(struct soap* soap, struct _tds__GetServices *tds__GetServices
- , struct _tds__GetServicesResponse *tds__GetServicesResponse)
- {
- DBG("__tds__GetServices\n");
-
- char _IPAddr[INFO_LENGTH];
- int i = 0;
- sprintf(_IPAddr, "http://%03d.%03d.%03d.%03d/onvif/services", 192, 168, 1, 233);
- tds__GetServicesResponse->__sizeService = 1;
-
- tds__GetServicesResponse->Service
- = (struct tds__Service *)soap_malloc(soap, sizeof(struct tds__Service));
- tds__GetServicesResponse->Service[0].XAddr
- = (char *)soap_malloc(soap, sizeof(char) * INFO_LENGTH);
- tds__GetServicesResponse->Service[0].Namespace
- = (char *)soap_malloc(soap, sizeof(char) * INFO_LENGTH);
- strcpy(tds__GetServicesResponse->Service[0].Namespace
- , "http://www.onvif.org/ver10/events/wsdl");
- strcpy(tds__GetServicesResponse[0].Service->XAddr, _IPAddr);
- tds__GetServicesResponse->Service[0].Capabilities = NULL;
- tds__GetServicesResponse->Service[0].Version
- = (struct tt__OnvifVersion *)soap_malloc(soap, sizeof(struct tt__OnvifVersion));
- tds__GetServicesResponse->Service[0].Version->Major = 0;
- tds__GetServicesResponse->Service[0].Version->Minor = 3;
- tds__GetServicesResponse->Service[0].__any
- = (char **)soap_malloc(soap, sizeof(char *));
- tds__GetServicesResponse->Service[0].__any[0]
- = (char *)soap_malloc(soap, sizeof(char) * INFO_LENGTH);
- strcpy(tds__GetServicesResponse->Service[0].__any[0],"why1");
- tds__GetServicesResponse->Service[0].__any[1]
- = (char *)soap_malloc(soap,sizeof(char) * INFO_LENGTH);
- strcpy(tds__GetServicesResponse->Service[0].__any[1],"why2");
- tds__GetServicesResponse->Service[0].__size = NULL;
- tds__GetServicesResponse->Service[0].__anyAttribute = NULL;
- return SOAP_OK;
- }
3、实现GetVideoSources命令
- int __tmd__GetVideoSources(struct soap* soap
- , struct _trt__GetVideoSources *trt__GetVideoSources
- , struct _trt__GetVideoSourcesResponse *trt__GetVideoSourcesResponse)
- {
- DBG("__tmd__GetVideoSources\n");
-
- int size1;
- size1 = 1;
- trt__GetVideoSourcesResponse->__sizeVideoSources = size1;
- trt__GetVideoSourcesResponse->VideoSources = (struct tt__VideoSource *)
- soap_malloc(soap, sizeof(struct tt__VideoSource) * size1);
- trt__GetVideoSourcesResponse->VideoSources[0].Framerate = 30;
- trt__GetVideoSourcesResponse->VideoSources[0].Resolution =
- (struct tt__VideoResolution *)soap_malloc(soap, sizeof(struct tt__VideoResolution));
- trt__GetVideoSourcesResponse->VideoSources[0].Resolution->Height = 720;
- trt__GetVideoSourcesResponse->VideoSources[0].Resolution->Width = 1280;
- trt__GetVideoSourcesResponse->VideoSources[0].token
- = (char *)soap_malloc(soap, sizeof(char)*INFO_LENGTH);
- strcpy(trt__GetVideoSourcesResponse->VideoSources[0].token,"GhostyuSource_token");
-
-
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging
- =(struct tt__ImagingSettings*)soap_malloc(soap, sizeof(struct tt__ImagingSettings));
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Brightness
- = (float*)soap_malloc(soap,sizeof(float));
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Brightness[0]
- = 128;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->ColorSaturation
- = (float*)soap_malloc(soap,sizeof(float));
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->ColorSaturation[0] = 128;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Contrast
- = (float*)soap_malloc(soap,sizeof(float));
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Contrast[0] = 128;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->IrCutFilter
- = (int *)soap_malloc(soap,sizeof(int));
- *trt__GetVideoSourcesResponse->VideoSources[0].Imaging->IrCutFilter = 0;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Sharpness
- = (float*)soap_malloc(soap,sizeof(float));
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Sharpness[0] = 128;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->BacklightCompensation
- = (struct tt__BacklightCompensation*)soap_malloc(soap
- , sizeof(struct tt__BacklightCompensation));
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->BacklightCompensation->Mode = 0;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->BacklightCompensation->Level = 20;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Exposure = NULL;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Focus = NULL;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->WideDynamicRange
- = (struct tt__WideDynamicRange*)soap_malloc(soap, sizeof(struct tt__WideDynamicRange));
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->WideDynamicRange->Mode = 0;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->WideDynamicRange->Level = 20;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->WhiteBalance
- = (struct tt__WhiteBalance*)soap_malloc(soap, sizeof(struct tt__WhiteBalance));
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->WhiteBalance->Mode = 0;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->WhiteBalance->CrGain = 0;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->WhiteBalance->CbGain = 0;
- trt__GetVideoSourcesResponse->VideoSources[0].Imaging->Extension = NULL;
- trt__GetVideoSourcesResponse->VideoSources[0].Extension = NULL;
- return SOAP_OK;
- }
__tmd__GetVideoSources最重要的是token的填充,必须要和下面profile中的sourcetoken相同,需要匹配到这个视频源
4、实现GetProfiles命令
- size = 1;
- trt__GetProfilesResponse->Profiles
- =(struct tt__Profile *)soap_malloc(soap, sizeof(struct tt__Profile) * size);
- trt__GetProfilesResponse->__sizeProfiles = size;
-
- i=0;
- trt__GetProfilesResponse->Profiles[i].Name
- = (char *)soap_malloc(soap,sizeof(char)*MAX_PROF_TOKEN);
- strcpy(trt__GetProfilesResponse->Profiles[i].Name,"my_profile");
- trt__GetProfilesResponse->Profiles[i].token
- = (char *)soap_malloc(soap,sizeof(char)*MAX_PROF_TOKEN);
- strcpy(trt__GetProfilesResponse->Profiles[i].token,"token_profile");
- trt__GetProfilesResponse->Profiles[i].fixed = _false;
- trt__GetProfilesResponse->Profiles[i].__anyAttribute = NULL;
除了上面的基本信息,还需要填充两大项:VideoSourceConfiguration和VideoEncoderConfiguration,一个用于描述视频源的信息,另外一个描述视频的编码信息
先给VideoSourceConfiguration分配空间
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration
- = (struct tt__VideoSourceConfiguration *)soap_malloc(soap
- ,sizeof(struct tt__VideoSourceConfiguration ));
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->Name
- = (char *)soap_malloc(soap,sizeof(char)*MAX_PROF_TOKEN);
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->token
- = (char *)soap_malloc(soap,sizeof(char)*MAX_PROF_TOKEN);
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->SourceToken
- = (char *)soap_malloc(soap,sizeof(char)*MAX_PROF_TOKEN);
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->Bounds
- = (struct tt__IntRectangle *)soap_malloc(soap,sizeof(struct tt__IntRectangle));
然后在填充它
-
- strcpy(trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->Name,"VS_Name");
- strcpy(trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->token,"VS_Token");
- strcpy(trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->SourceToken
- ,"GhostyuSource_token");
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->UseCount = 1;
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->Bounds->x = 1;
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->Bounds->y = 1;
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->Bounds->height = 720;
- trt__GetProfilesResponse->Profiles[i].VideoSourceConfiguration->Bounds->width = 1280;
如果是指针必须先用soap_malloc分配内存,然后才能赋值
下面是VideoEncoderConfiguration
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration
- = (struct tt__VideoEncoderConfiguration *)soap_malloc(soap
- ,sizeof(struct tt__VideoEncoderConfiguration));
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->Name
- = (char *)soap_malloc(soap,sizeof(char)*MAX_PROF_TOKEN);
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->token
- = (char *)soap_malloc(soap,sizeof(char)*MAX_PROF_TOKEN);
- strcpy(trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->Name,"VE_Name1");
- strcpy(trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->token,"VE_token1");
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->UseCount = 1;
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->Quality = 10;
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->Encoding
- = 1;
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->Resolution
- = (struct tt__VideoResolution *)soap_malloc(soap, sizeof(struct tt__VideoResolution));
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->Resolution->Height = 720;
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->Resolution->Width = 1280;
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->RateControl
- = (struct tt__VideoRateControl *)soap_malloc(soap, sizeof(struct tt__VideoRateControl));
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->RateControl
- ->FrameRateLimit = 30;
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->RateControl
- ->EncodingInterval = 1;
- trt__GetProfilesResponse->Profiles[i].VideoEncoderConfiguration->RateControl
- ->BitrateLimit = 500;
5、GetVideoSourceConfiguration和GetVideoEncoderConfiguration
- int __trt__GetVideoSourceConfiguration(struct soap* soap
- , struct _trt__GetVideoSourceConfiguration *trt__GetVideoSourceConfiguration
- , struct _trt__GetVideoSourceConfigurationResponse
- *trt__GetVideoSourceConfigurationResponse)
- {
- DBG("__trt__GetVideoSourceConfiguration\n");
-
- return SOAP_OK;
- }
-
- int __trt__GetVideoEncoderConfiguration(struct soap* soap
- , struct _trt__GetVideoEncoderConfiguration *trt__GetVideoEncoderConfiguration
- , struct _trt__GetVideoEncoderConfigurationResponse
- *trt__GetVideoEncoderConfigurationResponse)
- {
- DBG("__trt__GetVideoEncoderConfiguration\n");
- return SOAP_OK;
- }
6、GetVideoEncoderConfigurationOptions
- int __trt__GetVideoEncoderConfigurationOptions(struct soap* soap
- , struct _trt__GetVideoEncoderConfigurationOptions *trt__GetVideoEncoderConfigurationOptions
- , struct _trt__GetVideoEncoderConfigurationOptionsResponse
- *trt__GetVideoEncoderConfigurationOptionsResponse)
- {
- DBG("__trt__GetVideoEncoderConfigurationOptions\n");
-
- return SOAP_OK;
- }
以上5、6不分的代码直接返回SOAP_OK即可,正常来说是应该填充的,这里不影响RTSP Video Stream,暂时就不去动它
四、运行live555MediaServer服务器
live555官网有很多测试文件,我这里用的是MPEG4的测试文件路劲为rtsp://192.168.1.201/petrov.m4e
五、启动Onvif Device Manager测试
有一个问题,OnvifDeviceManager的并不能自动发现设备(OnvifTestTool可以),还好它提供了手动添加功能
单击add,添加如下内容:http://192.168.1.233/onvif/device_service
注意,我在程序中固定了两个IP:linux192.168.1.233,windows:192.168.1.201,这里需看情况修改
