#1395 closed defect (fixed)

collocated_ref_idx inference seems missing

collocated_ref_idx is not signalled when number of reference pictures is 1, but its value is used in collocated picture derivation. Inference to 0 when not present seems necessary in the semantics.

Thanks for reporting this, the following inference rule has already been incorporated and will be included in the next version of the standard:
"When not present, the value of collocated_ref_idx is inferred to be equal to 0."

  • Resolution set to fixed
  • Status changed from new to closed

The suggested semantic is present in the 2016/12 release of the HEVC specification.
