TDA2EXEVM: Encoder Force NAL unit

Raja Sekar M

Part Number: TDA2EXEVM

I am using vision sdk version 2.12. I am trying to capture and encode to h264 bitstream. I need NAL unit in every I-frame, but the encoder is giving at the start of sequence. How to force the encoder to set NAL unit at every I-frame.

I tried with "staticParams->nalUnitControlParams.naluPresentMaskIntraPicture" value of 0x2102

"ENCLINK_H264_SETNALU_MASK_SPS(staticParams->nalUnitControlParams.naluPresentMaskIntraPicture);
ENCLINK_H264_SETNALU_MASK_PPS(staticParams->nalUnitControlParams.naluPresentMaskIntraPicture);
ENCLINK_H264_SETNALU_MASK_SEI(staticParams->nalUnitControlParams.naluPresentMaskIntraPicture);"

Any suggestions?

Are you looking to output all frames are IDR frames?

All I-frames as IDR frames.

Pls find below the H264 Encoder configuration to output IDR only frames.

createStaticPrm->format = IVIDEO_H264HP;
createStaticPrm->profile = 100;
createStaticPrm->dataLayout = FIELD_SEPARATED;
createStaticPrm->fieldMergeEncodeEnable = FALSE;
createStaticPrm->enableAnalyticinfo = 0;
createStaticPrm->enableWaterMarking = 0;
createStaticPrm->maxBitRate = -1;
createStaticPrm->encodingPreset = XDM_USER_DEFINED;
createStaticPrm->rateControlPreset = IVIDEO_LOW_DELAY;
createStaticPrm->enableHighSpeed = FALSE;
createStaticPrm->enableSVCExtensionFlag = FALSE;
createStaticPrm->numTemporalLayer = 0;
createStaticPrm->overrideInputScanFormat= 0;
createStaticPrm->fieldPicEncode = 0;
createStaticPrm->IDRFrameInterval = 30;

createDynamicPrm->intraFrameInterval = 1;
createDynamicPrm->targetBitRate = 10*1000*1000;
createDynamicPrm->interFrameInterval = 1;
createDynamicPrm->mvAccuracy = IVIDENC2_MOTIONVECTOR_QUARTERPEL;
createDynamicPrm->inputFrameRate = 30;
createDynamicPrm->rcAlg = 0;
createDynamicPrm->qpMin = 0;
createDynamicPrm->qpMax = 51;
createDynamicPrm->qpInit = 25;
createDynamicPrm->vbrDuration = 8;
createDynamicPrm->vbrSensitivity = 0;
createDynamicPrm->maxPicSizeRatioI = 1;

Hi Shiju,

I tried with above settings, still having the same problem. I want to control this parameter "IDRFrameInterval".

Any suggestion?

Hi
I have valiadted this on top of VSDK3.0, exporting these paramters to Application layer is still not supported in VSDK3.0. You may need to hardcod these values in encLink_h264.c file

Hi,

Is there any document/link available for h264 codec?
