Function Documentation

void ReadFrameConcatenated	(	InputParameters *	p_Inp,
		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:

	p_Inp	Input configuration 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

void ReadFrameSeparate	(	InputParameters *	p_Inp,
		VideoDataFile *	input_file,
		int	FrameNoInFile,
		int	HeaderSize,

		unsigned char *	buf
	)

Reads one new frame from separate data files Code does not distinguish between planar and interleaved data.

Parameters:

	p_Inp	Input configuration 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	taget buffer
