Summary	0000336: Rate Control has some incompatibility problems with the Picture based Multi-pass encoding
Description	If I enable the RC mode 0, and use the frame level RC, the encode runs well. However, when I use the MB level RC, if the option "RDPictureDecision" is enabled,the encoder will output some errors like: Write into invalid memory in updateRCModel at frame 4, p_quad->NumberofBasicUnit -1 Write into invalid memory in updateRCModel at frame 4, p_quad->NumberofBasicUnit -2 Write into invalid memory in updateRCModel at frame 4, p_quad->NumberofBasicUnit -3 Write into invalid memory in updateRCModel at frame 4, p_quad->NumberofBasicUnit -4 Write into invalid memory in updateRCModel at frame 4, p_quad->NumberofBasicUnit -5 ..... This will be output by function updateRCModel when the option "BasicUnit" is great than 0. If the option "RDPictureDecision" is disabled, the MB level RC works well.
Steps To Reproduce	RateControlEnable=1, BasicUnit=1(>0) RDPictureDecision=1,
