kvz_filter_deblock_lcu()

void kvz_filter_deblock_lcu	(	encoder_state_t *const	state,
		int	x_px,
		int	y_px
	)

Filter the following vertical edges (horizontal filtering):

1. The left edge of the LCU.
2. All vertical edges within the LCU.

Filter the following horizontal edges (vertical filtering):

1. The rightmost 4 pixels of the top edge of the LCU to the left.
2. The rightmost 4 pixels of all horizontal edges within the LCU to the left.
3. The top edge and all horizontal edges within the LCU, excluding the rightmost 4 pixels. If the LCU is the rightmost LCU of the frame, the last 4 pixels are also filtered.

What is not filtered:

• The rightmost 4 pixels of the top edge and all horizontal edges within the LCU, unless the LCU is the rightmost LCU of the frame.
• The bottom edge of the LCU.
• The right edge of the LCU.

Parameters

state	encoder state
x_px	x-coordinate of the left edge of the LCU in pixels
y_px	y-coordinate of the top edge of the LCU in pixels
