MV encoding specification incorrect range #172

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Section 17.1 of the spec says:

17.1 Coding of Each Component
Each component is a signed integer V representing a vertical or horizontal luma 
displacement of V quarter-
pixels (and a chroma displacement of V eighth-pixels). The absolute value of V, 
if non-zero, is followed by a
boolean sign. V may take any value between -255 and +255, inclusive.

MVs are coded in quarter-pel, so V should be [-1023,1023].
