int dct_8x8	(	Macroblock *	currMB,
		ColorPlane	pl,
		int	b8,
		int *	coeff_cost,
		int	intra
	)

The routine performs transform,quantization,inverse transform, adds the diff. to the prediction and writes the result to the decoded luma frame. Includes the RD constrained quantization also.

Input:

b8: Block position inside a macro block (0,1,2,3).

Output:

nonzero: 0 if no levels are nonzero. 1 if there are nonzero levels. coeff_cost: Counter for nonzero coefficients, used to discard expensive levels.

int dct_8x8_cavlc	(	Macroblock *	currMB,

	)

The routine performs transform,quantization,inverse transform, adds the diff. to the prediction and writes the result to the decoded luma frame. Includes the RD constrained quantization also. Used for CAVLC.

Input:

b8: Block position inside a macro block (0,1,2,3).

Output:

nonzero: 0 if no levels are nonzero. 1 if there are nonzero levels. coeff_cost: Counter for nonzero coefficients, used to discard expensive levels.
