02/22/2024

Important Deprecated. This API may be removed from future releases of Windows. Applications should use the Media Session for playback.

Selects or deselects a stream.

Syntax

HRESULT SetStreamSelection(
  [in] DWORD dwStreamIndex,
  [in] BOOL  fEnabled
);

Parameters

[in] dwStreamIndex

Zero-based index of the stream. To get the number of streams, call IMFPMediaItem::GetNumberOfStreams.

[in] fEnabled

Specify whether to select or deselect the stream.

Value	Meaning
TRUE	The stream is selected. During playback, this stream will play.
FALSE	The stream is not selected. During playback, this stream will not play.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

You can use this method to change which streams are selected. The change goes into effect the next time that IMFPMediaPlayer::SetMediaItem is called with this media item. If the media item is already set on the player, the change does not happen unless you call SetMediaItem again with this media item.
