Xvid问题，请大家帮帮忙，谢谢
我Xvid编码一个图像数据，不知道怎么的编码后输出数据流为0
请帮我看看，就是inStream图形数据，编码后outStream为0，sucess非0

C/C++ code

    if(!this->m_EnHandle)    {        return -1;    }    xvid_enc_frame_t efXvid;    xvid_enc_stats_t esXvid;    memset(&efXvid,0,sizeof(efXvid));    memset(&esXvid,0,sizeof(esXvid));    esXvid.version=XVID_VERSION;    efXvid.version=XVID_VERSION;    efXvid.bitstream=outStream;                //加码数据流    efXvid.length=-1;    efXvid.input.csp=csp;    efXvid.input.plane[0]=inStream;    efXvid.input.stride[0]=stride;    int sucess=xvid_encore(this->m_EnHandle,XVID_ENC_ENCODE,&efXvid,&esXvid);

------解决方案--------------------------------------------------------
肯定是参数设置错误
看demo程序
你的图像数据是YUV格式么？
