Returns the media type for the output pin to use.
HRESULT GetMediaType(intiPosition,CMediaType* pMediaType);
Parameters
- iPosition
Position of the media type in the media type list. - pMediaType
Returned media type object.
Return Values
Returns an HRESULT value that depends on the implementation of the pure virtual CTransformFilter::GetMediaType member function.
HRESULT can include one of the following constants.
| Value | Description |
|---|---|
| NOERROR | A media type is returned. |
| S_FALSE | Although the iPosition parameter typically is valid, it does not correspond to a media type that is currently valid. |
| VFW_S_NO_MORE_ITEMS | The iPosition parameter is beyond the valid range. |
Use other standard error values, such as E_INVALIDARG, for error cases.
Remarks
This member function overrides the CBasePin::GetMediaType member function and calls the pure virtual CTransformFilter::GetMediaType member function, which must be overridden to return media types supported by your filter.
This is part of the implementation of CBasePin::EnumMediaTypes.
