Expand description
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
