IsSubpictureStreamEnabled Method

  • Článek

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Note

This component is available for use in the Microsoft Windows 2000, Windows XP, and Windows Server 2003 operating systems. It may be altered or unavailable in subsequent versions.

 

The IsSubpictureStreamEnabled method retrieves a value indicating whether the specified subpicture stream is enabled in the current title.

Value Description
0 to 31 subpicture stream

Return Value

Returns a Boolean value indicating whether the specified audio stream is available in the current title. True means it is available.
