Rotate iPhone video 90 degrees on Ubuntu

A very quick note about rotating .MOV videos shot on an iPhone 90 degrees clockwise on Ubuntu.  The first tool I tried was ffmpeg but it turns out that the Ubuntu version of ffmpeg isn't compiled with the -vf command-line option enabled. You could re-compile ffmpeg from source but it's easier to use mencoder:

sudo apt-get install mencoder
mencoder -vf rotate -o Input.MOV -oac lavc -ovc lavc Output.MOV
