Satya's blog - mencoder rotates video files

So I made a video with my cell phone camera held wrong, and to fix it I used this:

mencoder -o OUTFILE.dv \
    -vf-add rotate=1 \
    -vf-add scale=640:480 \
    INFILE.dv \
    -oac copy -ovc lavc

To keep aspect ratio and add black bars:

mencoder -o OUTFILE.dv \
    -vf-add rotate=1 \
    -vf-add scale=-10:480,expand=640:480
    INFILE.dv \
    -oac copy -ovc lavc

Winff can convert 3gp files to raw DV, but it's a GUI application.
