CTransInPlaceFilter::CheckTransform (Windows Embedded CE 6.0)
1/6/2010
Verifies that the media is supported by input and output pins.
Syntax
HRESULT CheckTransform(
const CMediaType* mtIn,
const CMediaType* mtOut
);
Parameters
- mtIn
Input pin media type.
- mtOut
Output pin media type.
Return Value
Returns S_OK by default.
Remarks
This member function overrides the CTransformFilter::CheckTransform member function.
The base class functions that call this member function are overridden in this class to call the CTransformFilter::CheckInputType member function that is overridden in the derived class, with the assumption that the type does not change.
Usually there is no reason for this member function to be called.
In debug builds some calls will be made, and returning S_OK ensures that these calls do not assert.
