Detailed Description

writing Type 2 (separate audio data) DV AVIs

This file type contains both audio and video tracks. It is therefore more compatible to certain Windows programs, which expect any AVI having both audio and video tracks. The video tracks contain the raw DV data (as in type 1) and the extracted audio tracks.

Note that because the DV data contains audio information anyway, this means duplication of data and a slight increase of file size.

Member Function Documentation

void AVI2File::Init	(	int	format,
		int	sampleFrequency,
		int	indexType
	)			[virtual]

Initialize the AVI structure to its initial state, either for PAL or NTSC format.

Initialize the AVIFile attributes: mainHdr, indx, ix00, idx1

Todo:

consolidate AVIFile::Init, AVI1File::Init, AVI2File::Init. They are somewhat redundant.

Parameters:

	format	pass AVI_PAL or AVI_NTSC
	sampleFrequency	the sample frequency of the audio content
	indexType	pass AVI_SMALL_INDEX or AVI_LARGE_INDEX
