[M4IF Technotes] MP4 files analysis with Dumpster

[Jean-Claude Dufourd]

Olivier,
Indeed Dumpster is the tool you want to use, if only because it is only
10kbytes and works very well and is intuitive...
Nothing from mpeg4ip can beat that. mp4tool also cannot compete.
The good thing about dumpster and mp4tool is that they come as a Windows
exe and you do not have to setup a huge compile environment.
However, you need to learn MP4 file format and OD framework before you
can use it. To get an idea of what is in the file before editing with
Dumpster, you can use the -xmlize option of mp4tool, which generates an
xml dump of the mp4 file. 
And finally, Dumpster is not a dumper only, it allows editing indeed
(using the bottom status line and the Apply button).
Best regards
