Upon further testing, I realized that this logic (both C and SIMD) overflows for 16-bit inputs. Will fix and resubmit. I also found that the C versions can be made slightly faster by returning out of the inner loop, which generates a shorter scalar version that is faster than the auto-vectorized abomination that was generated before. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
