hvcC should only contain nuh_layer_id == 0 NALUs. Support for a box meant to
contain higher layer NALUs will be added in a following patch.
To achieve this, all sources are parsed and filtered, including hvcC source
that until now were propagated untouched. This is reflected in how the affected
reference files now have ps_array_completeness set to 0 instead of 1 for some
non-PS NALUs.
Was the earlier stuff wrong?
Probably, but it's unlikely that any nuh_layer_id > 0 NALU was ever
written as it would have required either a broken isobmff source (where
such NALUs were wrongly put in hvcC for us to then blindly copy), or a
raw multilayer annex-b source.
