How can we convert the decoded data directly to RGB (24bit) and what will be the size of the RGB data.

I am new to the video domain.
I am using the Intel IPP Mpeg4 decoder sample.

I would recommend you to start from UMC documentation to learn how you can choose output color space for IPP video decoders.

The size of decoded data is quite easy to calculate. Assuming you do not pad end of frame lines for alignment the size of decoded RGB (24bits) frame is equal to = width*height*3.
