Constructor & Destructor Documentation

CAviFile::CAviFile	(	LPCTSTR	lpszFileName = _T("Output.avi"),
		DWORD	dwCodec = mmioFOURCC('M','P','G','4'),
		DWORD	dwFrameRate = 1
	)

Constructor accepts the filename, video code and frame rate settings as parameters. lpszFileName: Name of the output movie file to create dwCodec: FourCC of the Video Codec to be used for compression dwFrameRate: The Frames Per Second (FPS) setting to be used for the movie

The default Codec used here is MPG4. To use a different codec, pass its Fourcc value as the input parameter for dwCodec. For example, pass mmioFOURCC('D','I','V','X') to use DIVX codec, or pass mmioFOURCC('I','V','5','0') to use IV50 codec etc...

Also, you can pass just 0 to avoid the codecs altogether. In that case, Frames would be saved as they are without any compression; However, the output movie file size would be very huge in that case.

Finally, make sure you have the codec installed on the machine before passing its Fourcc here.
