SAV_PIX_FMT_YUV420P，1920*1080，iDataSize[0]=1920，iDataSize[1]=960，iDataSize[2]=960；pFrame->ppD ...

1920*1080 yuv420p情况下：
Y分量行数hs=hight = 1080   UV分量的行数hs2 = high/2 = 540
pFrame.ppData[0]  Y分量， pFrame.iDataSize[0] Y分量每行数据大小。数据大小=iDatasize[0]*hs=1920*1080 = 2073600
pFrame.ppData[1]  U分量， pFrame.iDataSize[1] U分量每行数据大小。数据大小=iDatasize[1]*hs2=960*540 = 518400
pFrame.ppData[2]  V分量， pFrame.iDataSize[2] V分量每行数据大小。数据大小=iDatasize[2]*hs2=960*540 = 518400
