Jan Beich <jbeich@FreeBSD.org> has asked multimedia@FreeBSD.org for maintainer-approval: Bug 208457: multimedia/ffmpeg: add ZIMG option (-vf zscale) https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D208457 Attachment 168876: v0 https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D168876&action=3Dedit --- Description --- >From ffmpeg-filters(1) manpage: zscale Scale (resize) the input video, using the z.lib library: https://github.com/sekrit-twc/zimg. The zscale filter forces the output display aspect ratio to be the s= ame as the input, by changing the output sample aspect ratio. If the input image format is different from the format requested by = the next filter, the zscale filter will convert the input to the request= ed format. Basic testing: $ ffmpeg -i /path/to/foo.mp4 -vf zscale=3Dw=3D320:h=3D-1 bar.mp4 $ mpv -vf lavfi=3D'"zscale=3Dw=3D320:h=3D-1"' /path/to/foo.mp4
