VirtualDub Plugin SDK 1.2

IVDXStreamSource interface

IVDXStreamSource:: GetDirectFormat

Obtains the direct format for the stream, if present.

const void *GetDirectFormat();

Thread safety

This method is not thread-safe.

Errors

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

Return value

A pointer to the direct format structure, or NULL if direct stream copy is not supported. The direct format is a VDXBITMAPINFOHEADER for a video stream and VDXWAVEFORMATEX for an audio stream.

Remarks

If an implementation wishes to support the direct stream copy feature, it must return a non-null direct format. This is the format that is used for the output stream. The pointer must remain valid for the life of the stream source. Currently, a direct format must always be exposed for an audio stream.
