--- Comment #1 from Jan Beich <jbeich at FreeBSD.org> ---
dav1d performance on i386 appears to be worse than aom. Tested on Intel
i7-6700K (Skylake) via 11.2 i386 jail on 13.0 amd64 host. Neither
CPUTYPE?=native nor -tilethreads help much.

$ fetch https://www.elecard.com/storage/video/Stream2_AV1_4K_22.7mbps.webm
$ ffmpeg -c:v libdav1d -i Stream2_AV1_4K_22.7mbps.webm -f null /dev/null
$ ffmpeg -c:v libaom-av1 -i Stream2_AV1_4K_22.7mbps.webm -f null /dev/null
