[Cin] SVT-AV1 works on i586, but slowly.

Installed SVT-AV1 1.5.0 from Slackbuilds on my Slackware 15.0 i586 it works, but at around 0.8 fps for 720p video ffmpeg -i MLP_animation_sleepsong_IeIDCNS-VUw.webm -s 1280x720 -an -f yuv4mpegpipe - | SvtAv1EncApp -i - -b mlp.ivf --passes 1 --rc 1 --tbr 1000 after looking at code I see all asm there is 64bit :) this explains why it is much faster on x86_64. Anyway, even 0.8 fps is ok for short (few mins) clips, I guess.
