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
);
Parameters
- dwOutputStreamIndex
Zero-based index of an output stream on the DMO.
- pmt
[in] Pointer to a DMO_MEDIA_TYPE structure that specifies the media type.
- dwFlags
Bitwise combination of zero or more flags from the DMO_SET_TYPE_FLAGS enumeration.
Return Value
Returns an HRESULT value. Possible values include the following.
Value | Description |
---|---|
S_OK |
Success |
S_FALSE |
Media type is not acceptable |
Invalid stream index |
|
Media type was not accepted |
Remarks
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.
