VirtualDub Plugin SDK 1.2

IVDXInputFile interface

IVDXInputFile:: GetAudioSource

Opens a stream on an input file.

bool GetAudioSource(int index, IVDXAudioSource **ppAS);

Parameters

index	Index of stream to open, where zero is the first stream, if any. Stream numbers must be contiguous.
ppAS	Pointer to variable to receive audio source for the stream.

Thread safety

This method is not thread-safe.

Errors

Errors may not be returned from this function (see SetError()).

Return value

True if successful, false if the stream with the given index does not exist.

Remarks

The audio stream object should have an outstanding reference on it. VirtualDub will call IVDXUnknown::Release() for this reference when it is finished with the object.

It is allowed to open an audio stream more than once; the returned audio source objects must be independent.
