我试图调整电影大小并使用ffmpeg逆时针旋转它。 我可以单独完成一个或另一个
ffmpeg -i MVI_8189.MOV -vf＆＃34; transpose = 2＆＃34; -ss 00:00:12 -t 00:00:05 rotate.MOV
OR
ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV
但如果我尝试两者兼顾，那么 -
ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV
ffmpeg -i resize.MOV -vf＆＃34; transpose = 2＆＃34; toutp.MOV
OR
ffmpeg -i MVI_8189.MOV -vf＆＃34; transpose = 2＆＃34; -ss 00:00:12 -t 00:00:05 rotate.MOV
ffmpeg -i rotate.MOV -s 406x720 toutp.MOV
最后一部电影不播放，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，一旦我试图播放它，我就无法播放任何其他电影（只有音频） - 快速时间不会退出，不断强制退出它。然后恢复的唯一方法似乎是重启OS-X
这虽然有效 -
ffmpeg -i MVI_8189.MOV -vf＆＃34; transpose = 2＆＃34; -ss 00:00:12 -t 00:00:05 rotate.MOV
ffmpeg -i rotate.MOV -s 720x406 toutp.MOV
但是没有做我想做的事 - 它以错误的方向拉伸电影
有什么想法吗？

答案 0 :(得分：1)
我会旋转，然后调整大小（反之亦然）。假设您希望输出视频宽度为1280像素，并且高度与输入宽高比成比例。
ffmpeg -i movie.mp4 -filter_complex " [0] transpose=dir=2 [rotated] ; [rotated] scale=1280:-2 " fixed_movie.mp4
-2参数使输出高度等于适当的宽高比，但可以被2整除。

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