Function Documentation

int ff_rle_encode	(	uint8_t *	outbuf,
		int	out_size,
		const uint8_t *	inbuf,
		int	bpp,
		int	w,
		int	add_rep,
		int	xor_rep,
		int	add_raw,
		int	xor_raw
	)

RLE compress the row, with maximum size of out_size.

Value before repeated bytes is (count ^ xor_rep) + add_rep. Value before raw bytes is (count ^ xor_raw) + add_raw.

Parameters:

	outbuf	Output buffer
	out_size	Maximum output size
	inbuf	Input buffer
	bpp	Bytes per pixel
	w	Image width

Returns:

Size of output in bytes, or -1 if larger than out_size
