Half-pel DSP context.

Fields§

§put_pixels_tab: [[op_pixels_func; 4]; 4]

Halfpel motion compensation with rounding (a+b+1)>>1. this is an array[4][4] of motion compensation functions for 4 horizontal blocksizes (8,16) and the 4 halfpel positions
pixels_tab[ 0->16xH 1->8xH ][ xhalfpel + 2yhalfpel ] @param block destination where the result is stored @param pixels source @param line_size number of bytes in a horizontal line of block @param h height

§avg_pixels_tab: [[op_pixels_func; 4]; 4]

Halfpel motion compensation with rounding (a+b+1)>>1. This is an array[4][4] of motion compensation functions for 4 horizontal blocksizes (8,16) and the 4 halfpel positions
pixels_tab[ 0->16xH 1->8xH ][ xhalfpel + 2yhalfpel ] @param block destination into which the result is averaged (a+b+1)>>1 @param pixels source @param line_size number of bytes in a horizontal line of block @param h height

§put_no_rnd_pixels_tab: [[op_pixels_func; 4]; 4]

Halfpel motion compensation with no rounding (a+b)>>1. this is an array[4][4] of motion compensation functions for 2 horizontal blocksizes (8,16) and the 4 halfpel positions
pixels_tab[ 0->16xH 1->8xH ][ xhalfpel + 2yhalfpel ] @param block destination where the result is stored @param pixels source @param line_size number of bytes in a horizontal line of block @param h height @note The size is kept at [4][4] to match the above pixel_tabs and avoid out of bounds reads in the motion estimation code.

§avg_no_rnd_pixels_tab: [op_pixels_func; 4]

Halfpel motion compensation with no rounding (a+b)>>1. this is an array[4] of motion compensation functions for 1 horizontal blocksize (16) and the 4 halfpel positions
pixels_tab[0][ xhalfpel + 2yhalfpel ] @param block destination into which the result is averaged (a+b)>>1 @param pixels source @param line_size number of bytes in a horizontal line of block @param h height
