well, why are 1,2 or 4 frames concatenated?
is it because of some requirement f the container? or is it arbitrary
and would any packing work if it where muxed?
would a (flv?) muxer work if it received only 4 frame packs? would it work
if it receive only 1 frames?
if these blocks ever need to be split than they definitly need to be split
in the demuxer or parser
can this packing change within a file, that is like 1,2,4,4,4,2,1,1,1 ...
or are there always the same number of frames packed together?
if it can change then they must be split in the demuxer or parser as
the alternative will make muxing in some containers much harder
if none of the above applied then its not strictly needed to spit but
its IMHO still a good idea to split them ...
