|FwStatus||fwiReconstructLumaIntraMB_H264_16s8u_C1R||(||Fw16s ** ppSrcCoeff, Fw8u * pSrcDstYPlane, Fw32s srcDstYStep, const FwIntra4x4PredMode_H264 * pMBIntraTypes, const Fw32u cbp4x4, const Fw32u QP, const Fw8u edgeType );|
|QP||Quantizer scale factor read from the bitstream.|
|cbp4x4||Coded block pattern. If cbp4x4 & (1<<(1+i))is not equal to 0 (0 < i < 16), i-th 4x4 AC. Luma block is not zero-filled and it exists in ppSrcCoeff.|
|edgeType||Specifies a vertical or horizontal edge.|
|pMBIntraTypes||Pointer to an array of Intra_4x4 luma prediction modes for eight subblocks. pMBIntraTypes[i] is defined in the same way as in PredictIntra_4x4_H264 function (0 < i < 8 ).|
|pSrcDstYPlane||Pointer to the current macroblock that is reconstructed in current Y-plane. This macroblock must contain inter prediction samples.|
|ppSrcCoeff||Double pointer to the order of 4x4 blocks of residual coefficients for a macroblock, the results of Huffman decoding (2x2 DC U-block, 2x2 DC V-block, 4x4 AC U-blocks, 4x4 AC V-blocks if the block is not zero-filled). The pointer is updated by the function and points to the blocks for the next macroblock.|
|srcDstYStep||Y-plane step size.|
This functions steps through a source Y plane buffer and reconstructs intra-frame predicted 4X4 luma macroblocks as follows.
Scales, performs an integer inverse transformation, and shifts each 4X4 block in accordance with JVTG050 8.5.8., in the order shown in JVTG050, Figure 6-6.
Performs intra-frame prediction for each 4X4 block in accordance with JVTG050 18.104.22.168.
Adds 4X4 inter-frame prediction blocks and 4X4 residual blocks in accordance with JVTG050, Figure 8-247.
Results are written back to the source plane buffers.
