DM8168 DVR_RDK4.0 编码H264 设置低码率（1M 或以下）高分辨率（1080P 30帧）视频有马赛克，部分参数设置如下：

encPrm.chCreateParams[ch].defaultDynamicParams.intraFrameInterval = 120;

encPrm.chCreateParams[ch].defaultDynamicParams.inputFrameRate = 30;

encPrm.chCreateParams[ch].defaultDynamicParams.targetFrameRate = 30;

encPrm.chCreateParams[ch].defaultDynamicParams.targetBitRate = 1*1000;
encPrm.chCreateParams[ch].defaultDynamicParams.mvAccuracy = IVIDENC2_MOTIONVECTOR_QUARTERPEL;
encPrm.chCreateParams[ch].defaultDynamicParams.rcAlg = 1;
encPrm.chCreateParams[ch].defaultDynamicParams.qpMin = 10;
encPrm.chCreateParams[ch].defaultDynamicParams.qpMax = 51;
encPrm.chCreateParams[ch].defaultDynamicParams.qpInit = -1;
encPrm.chCreateParams[ch].defaultDynamicParams.vbrDuration = 8;
encPrm.chCreateParams[ch].defaultDynamicParams.vbrSensitivity = 0;
