IMediaObject::SetInputType (Windows CE 5.0)

Send Feedback

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

HRESULT SetInputType(DWORDdwInputStreamIndex,const DMO_MEDIA_TYPE* pmt,DWORDdwFlags);

Parameters

  • dwInputStreamIndex
    Zero-based index of an input 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 Values

Returns an HRESULT value. Possible values include the following.

Value Description
S_OK Success
S_FALSE Media type is not acceptable
DMO_E_INVALIDSTREAMINDEX Invalid stream index
DMO_E_TYPE_NOT_ACCEPTED Media type was not accepted

Remarks

Call this method to test, set, or clear the media type on an input 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.

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

Requirements

OS Versions: Windows CE .NET 4.1 and later.
Header: Dmo.h.
Link Library: Dmoguid.lib.
