24 * Some explanation of the symbols used:
25 * Red/pink: intra block
28 * Yellow: B-block (not visualized properly yet)
30 * Motion vectors have black dot at their target (ie. at the MB center),
31 * instead of arrowhead. The black dot is enclosed in filled diamond with radius
32 * depending on reference frame number (one frame back = zero width, normal case).
34 * The intra blocks have generally lines drawn perpendicular
35 * to the prediction direction, so for example, if there is a pink block
36 * with horizontal line at the top of it, it is interpolated by assuming
37 * luma to be vertically constant.
38 * DC predicted blocks have both horizontal and vertical lines,
39 * pink blocks with a diagonal line are predicted using the planar function.
