macos - ffmpeg 旋转和调整大小

Question

我正在尝试调整电影的大小并使用 ffmpeg 逆时针旋转它。
我可以单独实现一个或另一个

ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

或者

ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

但如果我两者都尝试，要么——

ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

ffmpeg -i resize.MOV -vf "transpose=2" toutp.MOV

或者

ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

ffmpeg -i rotate.MOV -s 406x720 toutp.MOV

最终电影不播放，只有音频，没有视频；既不在 Finder 中预览，也不在 Quicktime 中预览。更严重的是，一旦我尝试播放它，我就无法播放任何其他电影(只有音频)-quicktime 不会退出，需要不断强制退出。然后恢复的唯一方法似乎是重新启动 OS-X
虽然这确实有效 -

ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

ffmpeg -i rotate.MOV -s 720x406 toutp.MOV

但没有做我想做的事——它把电影拉到了错误的方向
有任何想法吗？

Answer 1

更简单的版本:ffmpeg -i input.mp4 -vf "transpose=2,scale=720:-2" output.mp4
上面的命令将:

将视频逆时针旋转 90 度

缩放使(新)水平分辨率为 720

缩放以使新的垂直分辨率保持原始文件的纵横比

新的垂直可以被 2 整除，这是某些压缩编解码器所要求的，例如 h265
