Description

  1. At the end of 8.5.5.2 Derivation process for motion vectors and reference indices in subblock merge mode, the derivation process for motion vector arrays from affine control point motion vectors as specified in subclause 8.5.5.9 is invoked with a wrong number of inputs (refIdxLX is missing) and a wrong number of outputs (cbProfFlagLX and diffMvLX are missing).
  1. In 8.5.5.9 Derivation process for motion vector arrays from affine control point motion vectors, diffMvLX is mentioned as one of the outputs, but it is never derived in the process. There is however a variable diffMv derived at the end of this process. Are diffMv and diffMvLX intended to be the same?
