Hi sham .
U want to make streaming client (As I understood), For that first you make
sure which MPEG4 (ES or AVI  means Divx ) use are trying to decode , because
both have some diff marker and places so parsing will be differnt, If you
VLC is working in your case  then you can use  FFMPEG APIs (VLC uses FFMPEG)
MPEG 4 decoding because I think XVID (means xvidcore lib) gives MPEG4
ES.....so may be marker parsing cause a problem !!!!

Thanks
