DirectShow

[defused]

Hi all out there... i have a little problem with using DirecShow..
i got errors like the those shown below.. is there any1 who know how to debug it?

KNN error LNK2001: unresolved external symbol _CLSID_AudioCompressorCategory
KNN error LNK2001: unresolved external symbol _CLSID_FileWriter
KNN error LNK2001: unresolved external symbol _CLSID_FilterGraph
KNN error LNK2001: unresolved external symbol _CLSID_SystemDeviceEnum
KNN error LNK2001: unresolved external symbol _IID_IAMStreamConfig
KNN error LNK2001: unresolved external symbol _IID_IBaseFilter
KNN error LNK2001: unresolved external symbol _IID_ICreateDevEnum
KNN error LNK2001: unresolved external symbol _IID_IFileSinkFilter
KNN error LNK2001: unresolved external symbol _IID_IGraphBuilder
KNN error LNK2001: unresolved external symbol _IID_IMediaControl
KNN error LNK2001: unresolved external symbol _IID_IMediaEvent


The document from DirectShow says that Strmiids.lib are used to exports class identifiers (CLSIDs) and interface identifiers (IIDs). All DirectShow applications require this library. So i am wondering whether did i link this lib to my project. Is including <Dshow.h> just enough? But y am i still having the same errors???

you certainly must link Strmiids.lib to your project. Using code list below:

#pragma comment(lib,"Strmiids.lib")

Typing this to your the headline of your code file and try once again,good luck!
