Research direction
This is a provenance question, not a code change: check the diff of commit f1d06dc in the mp4box.js repository to see where cmex and cmin parsing was added, then read the surrounding box-parsing code in src/ to understand what they carry. Answering it means confirming whether the boxes are defined in ISO/IEC 14496-12 or 23008-12 by consulting those specifications or GPAC's own sources. Done looks like an authoritative citation and, if useful, a comment or doc line recording it.
