num_partitions_in_scheme_minus1 inference

Description

In the semantics of num_partitions_in_scheme_minus1, the inference rule should be :

The value of num_partitions_in_scheme_minus1[ h ][ 0 ] is inferred to be equal to NumLayersInIdList[ OlsIdxToLsIdx[ h ] ] − 1.

instead of:

The value of num_partitions_in_scheme_minus1[ h ][ 0 ] is inferred to be equal to NumLayersInIdList[ h ] − 1.

Indeed, NumLayersInIdList is accessed with a layer set idx, as it is done in the range constraint (The value of num_partitions_in_scheme_minus1[ h ][ j ] shall be in the range of 0 to NumLayersInIdList[ OlsIdxToLsIdx[ h ] ] – 1, inclusive.)

This issue is present in the latest published specification (04/2015), and concerns SHVC and MV-HEVC (as this definition is in annex F).
