You can ask them to stop filming. Most airlines have provisions in their CoC that you have to respect others' privacy and not be a general nuisance to the other passengers on the plane.
As for the GoPro, if the passenger has the window seat, he's allowed to film (assuming he's not causing damage to the window) or using a dangerous mount (eg, those cheap ones that are "arms" and aren't balanced). You can raise that with the cabin crew if there is a concern.
I haven't sat beside one, but if they're annoying me, I will ask them to stop and then failing that, ask the cabin crew to intervene. I can understand taking a few photos to "capture the memory", but to constantly annoy your neighbour...
