FFmpeg Rotate MP4 – How to Rotate an MP4 File by 90 Degrees

ffmpegrotate

Can I rotate (save, reencode) a .mp4 file with ffmpeg?

The only thing I found was on the mailinglist saying -vfilters "rotate=90" but ffmpeg says that "there are no vfilters". I tried -vf, it says there is "no rotate".

If I try to do it in VLC, it simply does not rotate and kills the audio. I'm on a Mac.

Maybe it should be configured with --enable-vfilters before compilation? BTW, mencoder does the job well, but you'll have to reencode the video:

mencoder -oac copy -ovc lavc -vf rotate=1 original.mp4 -o 90_CW_rotated.mp4 mencoder -oac copy -ovc lavc -vf rotate=2 original.mp4 -o 90_CCW_rotated.mp4
