[FFmpeg-user] Using ffprobe or ffmpeg to view atom metadata

[Steve Smith]

I was able to get exiftool to work. The format of the atom data isn't
exactly user friendly but I am to get the info I need. Thanks for the help.

Thanks for the suggestions. Unfortunately mediainfo doesn't seem to return
the atom metadata, and exiftool is throwing Perl errors.

Goto undefined subroutine &DynaLoader::bootstrap_inherit at
C:/Perl/lib/XSLoader.pm line 96.
Compilation failed in require at C:/Perl/lib/IO/Handle.pm line 260.

Realize this is getting off topic, but I'm kind of desparate for a way to
get at the atom metadata for these large mp4 files. There's no way to access
that info using ffmpeg or ffprobe?

This is a non-ffmpeg answer, but you could try:
exiftool -v4 YOURFILE.mov
or
mediainfo --inform='Details;1' YOURFILE.mov Dave Rice
