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

I had vfilters enabled. they just purged the algorithm from the packege, who knows why -_- I fixed it already, thanks. –  shox Aug 7 '10 at 18:15

With the current version pulled from SVN, you can rotate video using -vf "transpose=1".
Here's an example:

ffmpeg -vf "transpose=1" -i input.mp4 output.mp4

docs + options for transpose command are here

(here's how I built ffmpeg in case this helps)

svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
cd ffmpeg
./configure --enable-shared  --disable-mmx --arch=x86_64
make
sudo make install

Is there a reason you're disabling MMX? I don't see a point in that. –  cookiecaper Jan 27 '11 at 7:26
