各位前輩請教一下
我是用DSPACK來寫directshow的應用
我想呼叫出directshow中的CapturePin Property Page
下面的範例是我從amcaop中找出來的
我想請問的是pVCap可以從哪產生，如果要按照amcap中的範例來做，似乎還有很多的functions得要加入


[code cpp]
IAMStreamConfig *pSC;
hr = pBuild->FindInterface(&PIN_CATEGORY_CAPTURE,
&MEDIATYPE_Interleaved, pVCap,
::IID_IAMStreamConfig, (void **)&pSC);
if(hr != NOERROR)
hr = pBuild->FindInterface(&PIN_CATEGORY_CAPTURE,
&MEDIATYPE_Video, pVCap,
::IID_IAMStreamConfig, (void **)&pSC);
ISpecifyPropertyPages *pSpec;
CAUUID cauuid;
hr = pSC->QueryInterface(::IID_ISpecifyPropertyPages,(void **)&pSpec);
if(hr == S_OK)
{
hr = pSpec->GetPages(&cauuid);
hr = OleCreatePropertyFrame(NULL, 30, 30, NULL, 1,
(IUnknown **)&pSC, cauuid.cElems,
(GUID *)cauuid.pElems, 0, 0, NULL);
// !!! What if changing output formats couldn't reconnect
// and the graph is broken? Shouldn't be possible...
CoTaskMemFree(cauuid.pElems);
pSpec->Release();
}
pSC->Release();
[/code]

簡單的說...pVCap是一個GraphBuilder中的某一個已connect 的IBaseFilter....
依你的code來看...那個IBaseFilter 應該就是那capture的設備...
那個範例中..有一段是先透過 IEnumMoniker 將設備加入的...
