The output stream of test using the same parameters inconsistent #635

Run SvtHevcEncApp with the same command. The output stream is inconsistent. I think this should be a bug. Ghost_svt_hevc_9_3840x2160_4.log Ghost_svt_hevc_9_3840x2160_9.log Thanks.

@hanbing001 would you be able to provide a simplified command line with the SvtHevcEncApp and a way to obtain the clip used? I am unable to reproduce the issue with a local 4k clip

Sure. Maybe cqp is ok, only vbr have this issue. SvtHevcEncApp -i Ghost_Towns_4K_8bit_420_30fps.yuv -encMode 9 -w 3840 -h 2160 -bit-depth 8 -rc 1 –tbr 10000000 -fps 30 -b out.bin https://user-images.githubusercontent.com/22064979/231935874-36f5e3cc-145d-418c-9559-7d5f091132e9.mp4
