The AudioStreamsAvailable property retrieves the number of audio streams available in the current title.
VidWebDVD.AudioStreamsAvailable as Long
Parameters
This property takes no parameters.
Return Value
Returns an integer value from 1 through 8 representing the number of audio streams available in the current title.
Error Codes
If the property fails, Err.Number may be set to one of the following values.
| Value | Description |
|---|---|
| E_UNEXPECTED | Unspecified error. |
| E_NO_IDVD2_PRESENT | Unspecified internal error. |
| E_NO_DVD_VOLUME | No DVD available. |
| E_REGION_CHANGE_FAIL | The DVD has the wrong region code for this machine. |
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 0 through 7.
Discs generally present a menu showing the available soundtracks, which allows the user to select the audio stream to enable.
