void ReadFrameConcatenated	(	VideoDataFile *	input_file,
		int	FrameNoInFile,
		int	HeaderSize,
		FrameFormat *	source,
		unsigned char *	buf
	)

Reads one new frame from concatenated raw file Code does not distinguish between planar and interleaved data.

Parameters:

	input_file	Input file to read from
	FrameNoInFile	Frame number in the source file
	HeaderSize	Number of bytes in the source file to be skipped
	source	source file (on disk) information
	buf	image buffer data
