-NOTE: When IA OBUs are delivered over a protocol that does not provide explicit [=IA Sequence=] boundaries, a parser may locate the [=IA Sequence=] start by searching for the code <code>iamf</code> preceded by specific OBU header values. For example, by assuming that [=obu_extension_flag=] is set to 0 and because [=obu_trimming_status_flag=] is set to 0 for an [=IA Sequence Header OBU=], the OBU header can be 0xF806 or 0xFC06.
