VTM6.1中GOPsize为4时的IPPPIPPP....的程序配置

Question

VTM6.1中，我按照HM代码中配置的模式配置IPPPIPPP.....，但是在运行到第二个I帧的时候会出现报错

ERROR: In function "EncModeCtrlMTnoRQT::tryMode" in D:VTM源代码\VVCSoftware_VTM-VTM-6.1\source\Lib\EncoderLib\EncModeCtrl.cpp:1709: Inter-mode should not be in the I-Slice mode list!

我的配置如下：
#======== Coding Structure =============
IntraPeriod : 4 # Period of I-Frame ( -1 = only first)
DecodingRefreshType : 0 # Random Accesss 0:none, 1:CRA, 2:IDR, 3:Recovery Point SEI
GOPSize : 4 # GOP Size (number of B slice = GOPSize-1)
感恩大佬们能够解答，实在不胜感激！！！

这样改
#======== Coding Structure =============
IntraPeriod : 4 # Period of I-Frame ( -1 = only first)
DecodingRefreshType : 1 # Random Accesss 0:none, 1:CRA, 2:IDR, 3:Recovery Point SEI
GOPSize : 4 # GOP Size (number of B slice = GOPSize-1)
