Can one dump/extract the
Xtra atom from an MP4 file ? I am looking for a solution on a linux system (debian/jessie if possible).
Apparently this atom is used by WMP, as per link. I'd like to be able to use such information (rating, publisher or leveling inf) and pass that to my DLNA server (minidlna).
Currently all I see using
[...] Atom data @ 678585 of size: 529, ends @ 679114 Atom Xtra @ 679114 of size: 206, ends @ 679320 ~ Atom free @ 679320 of size: 48, ends @ 679368 Atom mdat @ 679368 of size: 248835382, ends @ 249514750 ~ denotes an unknown atom [...]
And same thing with
<UDTARecord Type="Xtra"> <UnknownBox> <BoxInfo Size="206" Type="Xtra"/> </UnknownBox>
Which cannot be used/parsed.
