Bugzilla Automation <bugzilla@FreeBSD.org> has asked freebsd-multimedia (Nobody) <multimedia@FreeBSD.org> for maintainer-feedback: Bug 262368: multimedia/ffmpeg: enable SVTAV1 on amd64 by default https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D262368 --- Description --- SVT-AV1 is a mature implementation of a fast AV1 encoder. It makes heavy us= e of threads and SIMD assembly thus better suited for live streaming (realtime encoding). $ ffmpeg -hide_banner -h encoder=3Dlibsvtav1 Encoder libsvtav1 [SVT-AV1(Scalable Video Technology for AV1) encoder]: General capabilities: delay threads Threading capabilities: other Supported pixel formats: yuv420p yuv420p10le libsvtav1 AVOptions: -hielevel <int> E..V.......
