Sachin Pandhare et al,
No.  It only supports sub-QCIF (128x96), QCIF (176x144), CIF (352x288), 4CIF, and 16CIF (depending on the "level" of the implementation) with a 4:2:0 sampling structure.  You are looking at the right place in the text.  What is not there is not supported (in short-header operation).
Best Regards,
Gary Sullivan

hello,
i have a small query:
does MPEG4 short header support VGA, QVGA formats which are not listed in the standard document.
I am refering to "Table 6-25 -- Parameters Defined by source_format Field" from MPEG4 standard doc ISO/IEC 14496-2:1999(E).
thanks,
Sachin
