Description

In 8.5.2.12 Derivation process for collocated motion vectors: "mvCol, refIdxCol, and listCol are set to mvLYCol[ xColCb ][ yColCb ], refIdxLYCol[ xColCb ][ yColCb ] and LY, respectively, with Y being equal to !X where X being the value of X this process is invoked for".
The value of X is a bit confusing in this process, since it is not listed in the list of inputs. Should it be added to the list of inputs?

It is implicitly given in the list of input:

– a reference index refIdxLX, with X being 0 or 1,

So when it is invoked for L0 X=0 and L1 X=1.
