And the checkasm also pass ./tests/checkasm/checkasm --test=vf_hflip --bench --seed 1616253308 benchmarking with native FFmpeg timers nop: 34.9 checkasm: using random seed 1616253308 SSSE3: - vf_hflip.hflip_byte [OK] - vf_hflip.hflip_short [OK] checkasm: all 2 tests passed hflip_byte_c: 28.0 hflip_byte_ssse3: 27.0 hflip_short_c: 277.7 hflip_short_ssse3: 71.0 Any ideas, why it fail for you ? In attach new patch (who probably doesn't fix the problem in your sandybox) 001 : unchanged 002 : add test for various width, change bench new, to use w variable and remove the fate-checkasm. Don't know if it's ok, to add a checkasm, without adding it to fate/checkasm (because it fails). It's convenient to have this kind of test to improve the asm (instead of not having a test at all) Martin
