CTransformOutputPin::GetMediaType (Compact 2013)
3/26/2014
Returns the media type for the output pin to use.
Syntax
HRESULT GetMediaType(
int iPosition,
CMediaType* pMediaType
);
Parameters
- iPosition
Position of the media type in the media type list.
- pMediaType
Returned media type object.
Return Value
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. |
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.
