Actually I think it should be possible to rotate the video image on the 
fly as it's rendered - that would require some computational power, but 
I bet that modern CPUs are plenty capable .

The user might also want to rotate a video file itself. For some video 
formats, it might also be possible to write metadata bits that say that 
the video should be rotated when displayed (just like we can for JPEG 
files).  For other formats, it might be necessary to rewrite the entire 
file to achieve a rotation.

This is a reasonable feature request.  I've filed a ticket:
