Public Function GetAudioData( _
   ByVal stream As Integer _
) As RasterNativeBuffer

Visual Basic (Usage)	Copy Code
Dim instance As CodecsExtensionList Dim stream As Integer Dim value As RasterNativeBuffer   value = instance.GetAudioData(stream)

public RasterNativeBuffer GetAudioData( 
   int stream
)

public:
RasterNativeBuffer GetAudioData( 
   int stream
) 

Parameters

stream

Index of the audio stream to retrieve. The extensions may have more than one audio stream. This index is 0-based. Therefore, the first stream is stream 0, the second stream is stream 1, etc. To retrieve all the audio streams, retrieve the streams one by one until an empty RasterNativeBuffer is returned (empty RasterNativeBuffer will have a RasterNativeBuffer.Data set to IntPtr.Zero and RasterNativeBuffer.Length set to 0.

Return Value

The audio data is stored inside extensions in the WAVE format.

The audio data can be played directly from memory, or the data can be written to a disk file and played from the disk. When writing the audio data to a disk file, give the file a .WAV extension.

The audio data pointer returned is freed automatically when this CodecsExtensionList object is disposed. so do not try to free this memory.
