IsAudioStreamEnabled Method

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IsAudioStreamEnabled method retrieves a value indicating whether the specified audio stream is enabled in the current title.

[bEnabled = ] MSWebDVD.IsAudioStreamEnabled(iStream)

Parameters

iStream

Specifies the audio stream as an Integer value from 0 through 7.

Return Value

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

Remarks

Although a disc can contain up to eight independent audio streams, each stream is not necessarily available for each title. For example, a main movie title might have three audio streams for English, Spanish, and Japanese, but the "Coming Attractions" title might have only one audio stream in English. Always verify that a stream is available for a title before setting the CurrentAudioStream property.
