Just because AVC is not a standard doesn't mean it's not proprietary.  We call 
proprietary anything that can't be implemented by the whole world without 
third-party permission.  If it serves the interest of the discussion better, 
let's eschew the world proprietary and use the words "non-free" or "unfree", 
both of which describe AVC well.
