Yes, some of the MMX implementations choose speed over accuracy, I ran to that myself when doing PPC versions. For a SSE version, if an accurate version is fast enough, please try to match the C version. Otherwise try to match MMX. - Lauri _______________________________________________ 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".
