Using MPEG4 Encoder in Short Header Mode (svhMode=1) for other than CIF and 4CIF

hi  all,

I am planning to used MPEG4 Encoder in Short Header mode.

while testing the codec I am getting SETPARAMS error while setting input image format other than CIF & 4CIF ( for example VGA, D1 .. etc ) while the encoder is configured in Short Header Mode. i am getting an error or 0x4001 if width is not same or 0x4002 if height is not same.

in datasheet and userguide of encoder its mention that input width/height should be greater than 192 and multiple of 16.

please do advice me on this..

Below given is my configuration used ..
