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.
[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. |
