Hi, everyone:
I am using dvrrdk 3.0 to encode video of 720P, and I get H264 video stream from ipcBitsOutRTOSLink, but mostly IDR NALU's size is biger than 64K Byte, I want to know is there has some parameters of enclink control the H264 nalu size? the EncLink_ChSliceCodingParams can be use for control H264 nalu size or not?
H264 enclink use IVIDEO_H264BP,when I set EncLink_ChCreateParams and EncLink_ChSliceCodingParams as follow:
encPrm.chCreateParams[i].format = chainsCfg->chCfg[i].encFormat;
encPrm.chCreateParams[i].profile = IVIDEO_H264BP;//chainsCfg->chCfg[i].encProfile;
encPrm.chCreateParams[i].dataLayout = IVIDEO_FIELD_SEPARATED;
encPrm.chCreateParams[i].fieldMergeEncodeEnable = FALSE;
encPrm.chCreateParams[i].enableAnalyticinfo = FALSE;
encPrm.chCreateParams[i].enableWaterMarking = FALSE;
encPrm.chCreateParams[i].encodingPreset = XDM_USER_DEFINED;
encPrm.chCreateParams[i].rateControlPreset = IVIDEO_USER_DEFINED;
encPrm.chCreateParams[i].enableHighSpeed = FALSE;
encPrm.chCreateParams[i].defaultDynamicParams.interFrameInterval = 1;
encPrm.chCreateParams[i].defaultDynamicParams.intraFrameInterval = chainsCfg->chCfg[i].intraFrameInterval;
encPrm.chCreateParams[i].defaultDynamicParams.inputFrameRate = chainsCfg->chCfg[i].inFrameRate;
encPrm.chCreateParams[i].defaultDynamicParams.targetFrameRate = chainsCfg->chCfg[i].encFrameRate;
encPrm.chCreateParams[i].defaultDynamicParams.targetBitRate = chainsCfg->chCfg[i].bitRate;
encPrm.chCreateParams[i].defaultDynamicParams.mvAccuracy = IVIDENC2_MOTIONVECTOR_QUARTERPEL;
encPrm.chCreateParams[i].defaultDynamicParams.rcAlg = chainsCfg->chCfg[i].rateCtrl;
encPrm.chCreateParams[i].defaultDynamicParams.qpMin = 0;
encPrm.chCreateParams[i].defaultDynamicParams.qpMax = 51;
encPrm.chCreateParams[i].defaultDynamicParams.qpInit = -1;
encPrm.chCreateParams[i].defaultDynamicParams.vbrDuration = 8;
encPrm.chCreateParams[i].defaultDynamicParams.vbrSensitivity = 0;
EncLink_ChDynamicParams *dynamicParams = &encPrm.chCreateParams[i].defaultDynamicParams;
dynamicParams->intraCodingParams.intraCodingPreset = IH264_INTRACODING_USERDEFINED;
dynamicParams->intraCodingParams.intraRefreshMethod = IH264_INTRAREFRESH_GDR;
dynamicParams->intraCodingParams.intraRefreshRate = chainsCfg->chCfg[i].inFrameRate;
EncLink_ChSliceCodingParams *sliceCodingParams = &dynamicParams->sliceCodingParams;
sliceCodingParams->sliceCodingPreset = IH264_SLICECODING_USERDEFINED;//IH264_SLICECODING_DEFAULT;//
sliceCodingParams->streamFormat = IH264_BYTE_STREAM;
sliceCodingParams->sliceMode = IH264_SLICEMODE_BYTES;
sliceCodingParams->sliceUnitSize = 1024;
execute code will occurs error like this:

anyone knows why, and give me some advices, thanks a lot.
