HEVC-编码器入口

1.encmain.cpp:

 //call encoding function调用编码函数===>编码函数入口!!!

 cTAppEncTop.encode(); 


 2.TAppEncTop.cpp:

 //call encoding function for one frame每读入一帧YUV调用一次!!!

 m_cTEncTop.encode( bEos, flush ? 0 : pcPicYuvOrg, m_cListPicYuvRec, outputAccessUnits, iNumEncoded );


 3.TEncTop.cpp:

 //compress GOP帧编码相关函数!!!

 m_cGOPEncoder.compressGOP(m_iPOCLast, m_iNumPicRcvd, m_cListPic, rcListPicYuvRecOut, accessUnitsOut);


 4.TEnGOP:cpp:

 //在最好的lamuda下进行编码。对每个sice进行编码!!!

 m_pcSliceEncoder->compressSlice   ( pcPic );


 5.TEncSlice.cpp:

 //run CU encoder 进行CU编码!!!

 m_pcCuEncoder->compressCU( pcCU );


 6.TEncCu.cpp:

 //analysis of CU  获取最佳PU为m_ppcBestCU[0]!!!

 xCompressCU( m_ppcBestCU[0], m_ppcTempCU[0], 0 );


 7.TEncCu.cpp:

 Void TEncCu::xCheckRDCostInter( TComDataCU*& rpcBestCU, TComDataCU*& rpcTempCU, PartSize ePartSize, Bool bUseMRG)

 Void TEncCu::xCheckRDCostIntra( TComDataCU*& rpcBestCU, TComDataCU*& rpcTempCU, PartSize eSize )


 8.TEncCu.cpp:

 Void TEncCu::xCheckRDCostIntra( TComDataCU*& rpcBestCU, TComDataCU*& rpcTempCU, PartSize eSize )

 这个函数内部实现对亮度和色度的预测；即：estIntraPredQT和estIntraPredChromaQT


 9.TEnSearch.cpp:

 Void TEncSearch::estIntraPredQT（......）中有四个关键的函数！

 ①：predIntraLumaAng实现了方向的预测

 ②：calcHAD函数计算了SATD

 ③：xModeBitsIntra函数计算编码的码率

 ④：xUpdateCandList更新最好的RDCost所使用的模式
