checks if the System is big- or little-endian

Returns:

0, little-endian (e.g. Intel architectures) 1, big-endian (e.g. SPARC, MIPS, PowerPC)

Reads one new frame from file.

Parameters:

	input_file	structure containing information (filename, format) about the source file
	FrameNoInFile	Frame number in the source file
	HeaderSize	Number of bytes in the source file to be skipped
	source	source file (on disk) information
	output	output file (for encoding) information
	pImage	Image planes
