int mavrix_mp4_dec_decode(void* p_handle, void * p_in_buf, int in_len,void * p_out_buf, int * p_out_len);
函数的出处在函数的实现中有详细的说明
还存在的问题：
1：对于NO_VOP的帧，还是解出来了，导致解的帧数增加
2：有些函数放的文件不妥，还需要进行移动
3：还需减少宏/表定义文件中宏/表的定义，将其转到只使用它的文件里
4: 文件和函数名，以后在修改

@ blues zhang, test foreman_qcif8.yuv(all asp) and carphone_qcif3.yuv(sp), decoded files are the same as original xvid decoder.
1.sepearate encoder and decoder.
2.delete files:
1) delete asm: bitstream,dct,image,quant,utils
2) encoder.c
3) xvid_encraw
4)delete vfw , plugin,dshow and debian directions
5)bench files
3. the decoding results of foreman_qcif8.yuv in debug version and release version are not the same, debug one is right. After installing vcsp6,it's ok.
4.disable xvid_encore in xvid.c
5.edit interfaces in libxvidcore.def by removing xvid_encore,xvid_plugin_2pass1,xvid_plugin_2pass2,xvid_plugin_single,xvid_plugin_lumimasking,xvid_plugin_dump,xvid_plugin_psnr;
