[Mp4-tech] Differences between MPEG4 and MPEG4S

[Saradhi DV.]

Dear Gary,
What I mean was MPEG4 Short headers.
I came to know that MPEG-4 Short headers means H.263 video stream
encapsulated with MPEG-4 video stream headers.
But is there any specification/documentation/reference code available
for this standard.
Regards,
Saradhi

Saradhi et al,
There is nothing formally called MPEG4s or MPEG4S.  You did not say
where you found that acronym, so it may be difficult to help you.  From
a quick web search, I noticed that some people seem to be referring to
"an MPEG4" as a video file that has been encoded in MPEG4 format, and
that some people seem to be pluralizing the term by adding an "s" on the
end.   So that having "some MPEG4s" refers to having some MPEG4-encoded
files (similar to the way some people refer to having some "MP3s" when
they refer to having some encoded audio files that use the MPEG-1 Layer
3 syntax).
Alternatively, one of the well-defined subsets of the technology in the
standard is called the "Simple profile".  Therefore, MPEG4S might
hypothetically refer to the Simple profile of MPEG4.
Best Regards,
Gary Sullivan
