Most of the features included in MPEG-4 are left to individual

are probably no complete implementations of the entire MPEG-4 set of
standards. To deal with this, the standard includes the concept of
"profiles" and "levels", allowing a specific set of capabilities

Do you see anything about QuickTime here? Do you really know
anything
about video programming? Have you ever written a demuxer or
muxer? Do
you know the MPEG format, sequence headers, etc? Have you ever
written
a stream parser?
Dream on.
Why so hostile?
Apple and Microsoft were the main contenders in a fight over which
file format would be
the basis of MPEG-4's file format. Apple won. It's only a minor PR
victory for Apple,
thought it made it MUCH easier for Apple to implement MPEG-4
support in Qucktime. I
have no idea which technology is superior, Apple's or Microsoft's,
but in fact, the MPEG-4
file format iis based on the ISO file format MP4 which in turn came
from QuickTime's file
format. Apple released all sorts of PR about it years ago and it
generated much
controversy because many people were hostile to anything from Apple
just because it
came from Apple instead of Microsoft.
Here's what the m4if.org, the website of the MP4 industry forum, ,
says about QuickTime's
file format:

I have heard that the MPEG-4 file format is the same as quicktime,
is that true?
No. Although Apple's QuickTime file format was adopted as the basis
for the MPEG-4 file
format, it has gone though many changes in order to support all the
functionality of
MPEG-4. Apple has however, played a key role in the development of
MP4, the MPEG-4 file
format.
It sounds like I read the same press releases you did, as what you
are saying is my recollection and understanding as well.
