value = instance.GetAudioData(stream)

public RasterNativeBuffer GetAudioData( 
   int stream
)

 function Leadtools.Codecs.CodecsExtensionList.GetAudioData( 
   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 Leadtools.RasterNativeBuffer is returned (empty Leadtools.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.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
