Detailed Description

AVC params

STRUCT MEMBERS: nSize : Size of the structure in bytes nVersion : OMX specification version information nPortIndex : Port that this structure applies to nSliceHeaderSpacing : Number of macroblocks between slice header, put zero if not used nPFrames : Number of P frames between each I frame nBFrames : Number of B frames between each I frame bUseHadamard : Enable/disable Hadamard transform nRefFrames : Max number of reference frames to use for inter motion search (1-16) nRefIdxTrailing : Pic param set ref frame index (index into ref frame buffer of trailing frames list), B frame support nRefIdxForward : Pic param set ref frame index (index into ref frame buffer of forward frames list), B frame support bEnableUEP : Enable/disable unequal error protection. This is only valid of data partitioning is enabled. bEnableFMO : Enable/disable flexible macroblock ordering bEnableASO : Enable/disable arbitrary slice ordering bEnableRS : Enable/disable sending of redundant slices eProfile : AVC profile(s) to use eLevel : AVC level(s) to use nAllowedPictureTypes : Specifies the picture types allowed in the bitstream bFrameMBsOnly : specifies that every coded picture of the coded video sequence is a coded frame containing only frame macroblocks bMBAFF : Enable/disable switching between frame and field macroblocks within a picture bEntropyCodingCABAC : Entropy decoding method to be applied for the syntax elements for which two descriptors appear in the syntax tables bWeightedPPrediction : Enable/disable weighted prediction shall not be applied to P and SP slices nWeightedBipredicitonMode : Default weighted prediction is applied to B slices bconstIpred : Enable/disable intra prediction bDirect8x8Inference : Specifies the method used in the derivation process for luma motion vectors for B_Skip, B_Direct_16x16 and B_Direct_8x8 as specified in subclause 8.4.1.2 of the AVC spec bDirectSpatialTemporal : Flag indicating spatial or temporal direct mode used in B slice coding (related to bDirect8x8Inference) . Spatial direct mode is more common and should be the default. nCabacInitIdx : Index used to init CABAC contexts eLoopFilterMode : Enable/disable loop filter
