| Microsoft DirectX 9.0 |
The AudioStreamsAvailable property retrieves the number of audio streams available in the current title.
Syntax
[ iStreams = ] MSWebDVD.AudioStreamsAvailable
Return Values
Returns an integer value from 1 through 8 representing the number of audio streams available in the current title.
Remarks
This property is read-only with no default value. The primary use of multiple audio streams is to provide movie soundtracks in more than one language. Typically, not every title on a disc has all audio streams enabled. For example, the feature movie might have soundtracks in three different languages, but the trailers might have only an English soundtrack. Before a user can select a stream, the application must determine which streams are available within the current title. Note that particular streams are identified by an index from zero through 7.
Discs generally present a menu showing the available soundtracks, enabling the user to select the audio stream to enable.
