Explanation:
My ADTF-Filter gets as input two double values and its output is a struct. The struct contains a few double values.
typedef struct {
double ValueX;
double ValueY;
double ValueZ;
} tStruct;
My problem:
I wanted to see my values in "Signal View" But I'm getting this error:
warning | 00:00:15:015 | Media Description Service: No Media Description found for struct type '' on pin 'Filter/ValueX/'. This pin will not be available in SignalView! | media_description_signal_provider.cpp(158) | 12736/8516 | C:\tools\ADTF\2.14.2\bin\adtf_devenv.exe | OK | No error | cMediaManager_plugin
What I have tried
I played around a bit with the MediaDescription Editor and tried to see how it is done in the examples given by adtf. But nothing is working so far.

警告(无错误)准确描述了所缺少的内容:您正在使用结构的输出引脚上没有设置“媒体描述”。
我猜您在Init方法中使用的是这样的内容:
m_oOutputPin.Create("output", cObjectPtr<IMediaType>(new cMediaType(0, 0)), static_cast<IPinEventSink*> (this));
因此,您必须使用结构扩展媒体类型的创建:
m_oOutputPin.Create("output", cObjectPtr<IMediaType>(new cMediaType(0, 0, 0, "tStruct")), static_cast<IPinEventSink*> (this));
然后将根据您的结构对其进行设置和生成。
