Sorry, I had missed your reply.
The specification on how sampling rate is to be stored should it be
greater than INT16_MAX is a FLAC in ISOBMFF requirement:
https://git.xiph.org/?p=flac.git;a=blob;f=doc/isoflac.txt;h=574df9f54a779fca2e62c726703fc7be199d4c05;hb=refs/heads/master#l165
It definitely could be applied to other codecs, but I haven't seen
such requirements clearly defined.
ISOBMFF only defines that AudioSampleEntryV1 should be used instead,
in which case the sampling_rate is a 32 bits integer (ISO 14496-12
12.2.3.2)
