Sorry for the delay. Here's a test file: http://www.mediafire.com/file/awg5lfy4j2dv85k/testfile.opus/file <http://www.mediafire.com/file/awg5lfy4j2dv85k/testfile.opus/file> >>> On something called "X-Gene" Linux, I see a 2,5% overall >>> speedup (126x to 129x) >>> >>> The issue is that there is some probability that your patch will >>> break mac and Windows compilation, so I would at least >>> like to understand why I can not reproduce your speedup. >>> >> >> I tested this on real hardware. >> > > Is X-Gene not real hardware? > Didn't find much about it at all. If you don't get performance improvements I think someone with a more popular board should test it. >> How can this break mac support at all when it doesn't >> support aarch64? >> > > Have you heard of iPhones? > Those use iOS. >> And I can't find a windows aarch64 compiler either. >> > > There is one (I don't know more). > I still don't know how you can suggest this patch will break any operating systems when you haven't tested either. _______________________________________________ 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".
