This requires many further changes to compile.
Abandoning, even though displaying <MovieBox Container="file cmvd"> is misleading for an AVIF file.

Adapting gf_isom_box_dump_start_ex() to print the actual box parent instead of the possible containers would be another way to go:

gpac/src/isomedia/box_funcs.c

Line 2283 in b779331

gf_fprintf(trace, "Container=\"%s\" ", a->registry->parents_4cc);

but gf_isom_box_dump_start() does not provide this context and is called too many times.

I patched the container code for cmov/cmvd which were indeed wrong. Note that MP4Box -diso will not show cmof/cmvd as these are lost when we load the file; they can only be seen when activating logs for container@debug.
