Fields

source: i32

Where the current macroblock comes from; negative value when it comes from the past, positive value when it comes from the future. XXX: set exact relative ref frame reference instead of a +/- 1 “direction”.

w: u8

Width and height of the block.

h: u8

Width and height of the block.

src_x: i16

Absolute source position. Can be outside the frame area.

src_y: i16

Absolute source position. Can be outside the frame area.

dst_x: i16

Absolute destination position. Can be outside the frame area.

dst_y: i16

Absolute destination position. Can be outside the frame area.

flags: u64

Extra flag information. Currently unused.

motion_x: i32

Motion vector src_x = dst_x + motion_x / motion_scale src_y = dst_y + motion_y / motion_scale

motion_y: i32

Motion vector src_x = dst_x + motion_x / motion_scale src_y = dst_y + motion_y / motion_scale

motion_scale: u16
