SVT HEVC encoder. Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel® Xeon® processors. Using the open source SVT-HEVC encoder, it is possible to spread video encoding processing across multiple Intel® Xeon® processors to achieve a real advantage of processing efficiency.

signal SIGFPE would happen when setting VBV options under CQP rate control mode. #401
When encoding with either "-vbv-maxrate" or "-vbv-bufsize" set under CQP rate control mode (-rc 0), we would get such encoding crash:
