I’m looking for this software but don’t know the name.
Software that atom parsing MPEG files
>Solution :
I’m reluctant to provide specific recommendations, so I’ll suggest some approaches to solving the problem:
-
a search for "MPEG4 validation" or "ISOBMFF validation" will probably get you to something like MP4Box, which has an online version – https://gpac.github.io/mp4box.js/test/filereader.html
(and you can self-host), command line tools like https://github.com/amarghosh/mp4viewer and similar commercial options. -
you could also use https://github.com/MPEGGroup/isobmff or similar software to build something yourself.
