Whilst you don't have to. I would expect to be able to based upon the 
docs saying:-

"‘x264opts options’

     Allow to set any x264 option, see x264 –fullhelp for a list. "

Since "profile" is an option listed by "x264 –fullhelp" I see no reason 
why it should not work.

I understood the direct approach of -profile was retained for backwards 
API compatibility, but as we have already discussed, that too has 
changed to vprofile.....
