Detailed Description

Declares high level functions to search through intra modes.

Function Documentation

set_y_mode_and_delta_angle()

void set_y_mode_and_delta_angle	(	const int	mode_idx,
		MB_MODE_INFO *const	mbmi,
		int	reorder_delta_angle_eval )

set the luma intra mode and delta angles for a given mode index. The total number of luma intra mode is LUMA_MODE_COUNT = 61. The first 13 modes are from DC_PRED to PAETH_PRED, followed by directional modes. Each of the main 8 directional modes have 6 = MAX_ANGLE_DELTA * 2 delta angles.

Parameters

[in]	mode_idx	mode index in intra mode decision process.
[in]	mbmi	Pointer to structure holding the mode info for the current macroblock.
[in]	reorder_delta_angle_eval	Indicates whether to reorder the evaluation of delta angle modes.
