Have you looked at the MPEG-4 Part 2 specification? 

This should detail the steps involved.

Hi
Normally for video encoding, the steps followed are:

1) Color Space of original data changed to YUV.
2) Color Space SubSampling.
3) Discrete Cosine Transformation.
4) Quantization.
5) Run Length Encoding.
6) I-frame or P-frame and B-frame encoding.
7) Image division to Macroblock.
8) Motion Prediction and Compensation.
9) Error Prediction.

i want to ask you that, does XviD follow all these steps,or there are
any extra steps which it follow or any steps which it skips.If it
follows the above steps, then where actually in the source code,this DCT
and Quantization takes place.
Also tell me whether  the above steps are sufficient for MPEG-4 ASP
video encoding.If not then tell me what else i have to follow.
