its surely possible to add a
that could even export the version on demuxing ...
also i tend slightly toward either leaving the dummy formats for 3g2,...
or adding a seperate field like int ftyp= MKTAG('3','g'...
but id like to think about the second part a little more
because ftyp somehow is different from version in the 1.0, 2.0 ... sense
its more "which of the half compatible standards from which comitee should
be picked" while version is more in the "2.0" is the current "1.0" is old and
superseded deprecated dont use it ...
adding a int (file_)version though should be ok if anyone wants it
