linux设备上的Onvif 实现13: 获取子通道的配置数据范围

1 背景

想要修改配置数据，必须知道摄像头支持的数据范围，这样才能设置成正确的数据。

2 函数原型

SOAP_FMAC5 int SOAP_FMAC6 soap_call___ns8__GetVideoEncoderConfigurationOptions(struct soap *soap, const char *soap_endpoint, const char *soap_action, struct _ns8__GetVideoEncoderConfigurationOptions *ns8__GetVideoEncoderConfigurationOptions, struct _ns8__GetVideoEncoderConfigurationOptionsResponse
*ns8__GetVideoEncoderConfigurationOptionsResponse)

该函数需要指定通道代号、该通道的功能种类（例如本例中的编码器代号）

getOptionsReq.ConfigurationToken

getOptionsReq.ProfileToken

3 我的代码实例：

/* 读取子通道的配置数据范围.

一般2通道，第1是主通道，第2是子通道。 */

struct _ns8__GetVideoEncoderConfigurationOptions getOptionsReq;

struct _ns8__GetVideoEncoderConfigurationOptionsResponse getOptionsResponse;

if(count>1)

channel=1;

else

channel=0;

getOptionsReq.ConfigurationToken = deviceode->profile[channel].VideoEncoderConfigurationtoken;

getOptionsReq.ProfileToken = deviceode->profile[channel].token;

result = soap_call___ns8__GetVideoEncoderConfigurationOptions(soap, deviceode->mediauri, NULL, &getOptionsReq, &getOptionsResponse);

if(result==-1)

{

printf("soap error: %d, %s, %s\n", soap->error, *soap_faultcode(soap), *soap_faultstring(soap));

result = soap->error;

return FALSE;

}

else

{

printf(" GetVideoEncoderConfigurationOptions OK! \n");

/* 有的摄像头应答无Extension字段，有的有Extension字段。

Extension字段中含码率BitrateRange范围定义 */

#if 1

printf(" getOptionsResponse.Options->QualityRange=(%d ~ %d) \n", getOptionsResponse.Options->QualityRange->Min,getOptionsResponse.Options->QualityRange->Max);

printf(" getOptionsResponse.Options->H264->__sizeResolutionsAvailable=%d \n", getOptionsResponse.Options->H264->__sizeResolutionsAvailable);

struct ns3__VideoResolution *ResolutionsAvailable;

ResolutionsAvailable = getOptionsResponse.Options->H264->ResolutionsAvailable;

count = getOptionsResponse.Options->H264->__sizeResolutionsAvailable;

for(i=0; i<count;i++)

{

printf(" getOptionsResponse.Options->H264->ResolutionsAvailable[%d]=(%d x %d) \n", i,ResolutionsAvailable->Width,ResolutionsAvailable->Height);

ResolutionsAvailable++;

}

printf(" getOptionsResponse.Options->H264->GovLengthRange=(%d ~ %d) \n", getOptionsResponse.Options->H264->GovLengthRange->Min,getOptionsResponse.Options->H264->GovLengthRange->Max);

printf(" getOptionsResponse.Options->H264->FrameRateRange=(%d ~ %d) \n", getOptionsResponse.Options->H264->FrameRateRange->Min,getOptionsResponse.Options->H264->FrameRateRange->Max);

printf(" getOptionsResponse.Options->H264->EncodingIntervalRange=(%d ~ %d)\n", getOptionsResponse.Options->H264->EncodingIntervalRange->Min,getOptionsResponse.Options->H264->EncodingIntervalRange->Max);

printf(" getOptionsResponse.Options->H264->__sizeH264ProfilesSupported=%d \n", getOptionsResponse.Options->H264->__sizeH264ProfilesSupported);

printf(" getOptionsResponse.Options->H264->H264ProfilesSupported=%d \n", *getOptionsResponse.Options->H264->H264ProfilesSupported);

if(getOptionsResponse.Options->Extension!=NULL)

printf(" getOptionsResponse.Options->Extension->H264->BitrateRange=(%d ~ %d) \n", getOptionsResponse.Options->Extension->H264->BitrateRange->Min,getOptionsResponse.Options->Extension->H264->BitrateRange->Max);

#endif

}

4 命令及应答报文

linux服务器发出命令 GetVideoEncoderConfigurationOptions，获取配置参数的范围。
