5.3 Controlling Driver
The ADLINK HDV62 Video Capture filter provides property pages
and exposes COM interfaces to control video. So an application
can have two ways to control video configurations: using the prop-
erty pages and using the COM interfaces.
5.3.1 Use Property Pages
There are two embedded property pages in the driver. To show
these property pages, use Windows API:
OleCreatePropertyFrame .
Documentation about Displaying a Filter’s Property Page can be
found on Microsoft MSDN homepage.
Below is the example code for adding property pages:
// pFilter points to an ADLINK HDV62 Video Capture
filter
// or an ADLINK HDV62 Crossbar filter
ISpecifyPropertyPages *pSpecify;
HRESULT hr;
hr = pFilter-
>QueryInterface(IID_ISpecifyPropertyPages, (void
**)&pSpecify);
if (SUCCEEDED(hr))
{
FILTER_INFO FilterInfo;
pFilter->QueryFilterInfo(&FilterInfo);
FilterInfo.pGraph->Release();
CAUUID caGUID;
pSpecify->GetPages(&caGUID);
pSpecify->Release();
OleCreatePropertyFrame(
NULL, // Parent window
0, // x (Reserved)
0, // y (Reserved)
FilterInfo.achName,// Caption for the
dialog box
1, // Number of filters
