Describe the issue
ISO/IEC 14496-12:2022 Sections 8.7.8 and 8.7.9 describe the SampleAuxilaryInformationSizesBox and SampleAuxiliaryInformationOffsetsBox respectively. These boxes need to be consistent with other boxes under stbl and traf respectively to be useful.
To Reproduce
N/A.
Detailed analysis
There are requirements that the sample_count needs to meet (given the Semantics section).
Potentially the aux_info_type and aux_info_parameter values in saiz and saio should match up (i.e. there should be pairwise equivalency), although that is only implied in the standard, not actually required. At a stretch, CW could check the type against the known types and possibly validate that parameters are present / absent.
