hi experts,
As we use videnctest, we found lot of parameters as below
VIDENC2_Params *params = enc->params;
params->maxHeight = enc->height;
params->maxWidth = enc->width;
...
params->maxBitRate = -1; //IGNORED
params->minBitRate = 0;
...
params->numInputDataUnits = 0;
params->numOutputDataUnits = 0;
...
h264enc_params->rateControlParams.qpI = 28;
h264enc_params->rateControlParams.qpMaxI = 36;
h264enc_params->rateControlParams.qpMinI = 10;
h264enc_params->rateControlParams.qpP = 28;
h264enc_params->rateControlParams.qpMaxP = 40;
h264enc_params->rateControlParams.qpMinP = 10;
h264enc_params->rateControlParams.qpOffsetB = 4;
h264enc_params->rateControlParams.qpMaxB = 44;
h264enc_params->rateControlParams.qpMinB = 10;
h264enc_params->rateControlParams.allowFrameSkip = 0;
h264enc_params->rateControlParams.removeExpensiveCoeff = 0;
h264enc_params->rateControlParams.chromaQPIndexOffset = 0;
h264enc_params->rateControlParams.IPQualityFactor = IH264_QUALITY_FACTOR_DEFAULT; // 0
h264enc_params->rateControlParams.initialBufferLevel = 64000;
h264enc_params->rateControlParams.HRDBufferSize = 64000;
h264enc_params->rateControlParams.minPicSizeRatioI = 0;
h264enc_params->rateControlParams.maxPicSizeRatioI = 20;
...
mpeg4enc_params->rateControlParams.rateControlParamsPreset = IMPEG4_RATECONTROLPARAMS_DEFAULT;
mpeg4enc_params->rateControlParams.rcAlgo = IMPEG4_RATECONTROLALGO_VBR;
mpeg4enc_params->rateControlParams.qpI = 5;
mpeg4enc_params->rateControlParams.qpP = 5;
mpeg4enc_params->rateControlParams.seIntialQP = 5;
mpeg4enc_params->rateControlParams.qpMax = 31;
mpeg4enc_params->rateControlParams.qpMin = 1;
mpeg4enc_params->rateControlParams.enablePerceptualQuantMode = 0;
mpeg4enc_params->rateControlParams.allowFrameSkip = 0;
mpeg4enc_params->rateControlParams.initialBufferLevel = 0;
mpeg4enc_params->rateControlParams.vbvBufferSize = 0;
mpeg4enc_params->rateControlParams.qpMinIntra = 0;
Is there any document to talk about the range of these parameters for each codec and common setting??
Thanks
