IMediaObject::SetOutputType (Windows Embedded CE 6.0)

1/6/2010

This method sets the media type on an output stream or tests whether a media type is acceptable.

Syntax

HRESULT SetOutputType(
  DWORD dwOutputStreamIndex,
  const DMO_MEDIA_TYPE* pmt,
  DWORD dwFlags
);

dwFlags
Bitwise combination of zero or more flags from the DMO_SET_TYPE_FLAGS enumeration.

Returns an HRESULT value. Possible values include the following.

Call this method to test, set, or clear the media type on an output stream:

To test the media type without setting it, use the DMO_SET_TYPEF_TEST_ONLY flag. If the media type is not acceptable, the method returns S_FALSE.
To set the media type, set dwFlags to zero. If the media type is not acceptable, the method returns DMO_E_TYPE_NOT_ACCEPTED.
To clear the current media type (if any), use the DMO_SET_TYPEF_CLEAR flag and set pmt to NULL. When the method returns, the stream no longer has a media type. The DMO cannot process samples until the application sets a new media type, unless the stream is optional.

The media types that are currently set on other streams can affect whether the media type is acceptable.
