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.
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.

Requirements

Header	dshow.h, Streams.h
Library	ole32.lib, Ole32auth.lib, Strmbase.lib, Strmiids.lib, uuid.lib
