Andrey Semashev:

When adding analysis-reuse-level=10 option on the first pass encode, x265 crashes with a segmentation fault.

I’m using libx265 3.2.1 through ffmpeg 4.2.1. The full command line is:

‌

ffmpeg -y -i "$INPUT" -map 0:v:0 -c:v:0 libx265 -preset "veryslow" -crf 28 -x265-params "analysis-reuse-level=10:ssim-rd=1:multi-pass-opt-distortion=1:multi-pass-opt-analysis=1:stats=$\{INPUT\}.x265.log:analysis-reuse-file=$\{INPUT\}.x265.analysis.dat:no-slow-firstpass=1:pass=1" -an -threads 0 -f matroska /dev/null
