Speed related whine

So my 335i 6mt xdrive makes a whining sound related to vehicle speed. It pretty much sounds the same when accelerating, coasting out of gear, maintaining speed and decelerating. It's noisiest at around 20-40 MPH. It's kind of hard to tell where it is coming from, but I think it my be the transfer case. Anyone else experience this? Her is a video.

Could be a wheel bearing.
