Fields

iUsageType: EUsageType

< application type;1.CAMERA_VIDEO_REAL_TIME:camera video signal;2.SCREEN_CONTENT_REAL_TIME:screen content signal;

iPicWidth: c_int

< width of picture in luminance samples (the maximum of all layers if multiple spatial layers presents)

iPicHeight: c_int

< height of picture in luminance samples((the maximum of all layers if multiple spatial layers presents)

iTargetBitrate: c_int

< target bitrate desired, in unit of bps

iRCMode: RC_MODES

< rate control mode

fMaxFrameRate: f32

< maximal input frame rate

iTemporalLayerNum: c_int

< temporal layer number, max temporal layer = 4

iSpatialLayerNum: c_int

< spatial layer number,1<= iSpatialLayerNum <= MAX_SPATIAL_LAYER_NUM, MAX_SPATIAL_LAYER_NUM = 4

sSpatialLayers: [SSpatialLayerConfig; 4]

iComplexityMode: ECOMPLEXITY_MODE

uiIntraPeriod: c_uint

< period of Intra frame

iNumRefFrame: c_int

< number of reference frame used

eSpsPpsIdStrategy: EParameterSetStrategy

< different stategy in adjust ID in SPS/PPS: 0- constant ID, 1-additional ID, 6-mapping and additional

bPrefixNalAddingCtrl: bool

< false:not use Prefix NAL; true: use Prefix NAL

bEnableSSEI: bool

< false:not use SSEI; true: use SSEI -- TODO: planning to remove the interface of SSEI

bSimulcastAVC: bool

< (when encoding more than 1 spatial layer) false: use SVC syntax for higher layers; true: use Simulcast AVC

iPaddingFlag: c_int

< 0:disable padding;1:padding

iEntropyCodingModeFlag: c_int

< 0:CAVLC 1:CABAC.

bEnableFrameSkip: bool

< False: don't skip frame even if VBV buffer overflow.True: allow skipping frames to keep the bitrate within limits

iMaxBitrate: c_int

< the maximum bitrate, in unit of bps, set it to UNSPECIFIED_BIT_RATE if not needed

iMaxQp: c_int

< the maximum QP encoder supports

iMinQp: c_int

bUseLoadBalancing: bool

< only used when uiSliceMode=1 or 3, will change slicing of a picture during the run-time of multi-thread encoding, so the result of each run may be different
