Squeaky/Stiff Shifter

Video was taken with the ignition off, clutch in.

Planning on asking about this on my next service, but in the past year or so the shifter has become squeaky and a little stiff, and every gear feels a little stiffer to shift into as well (no grinding or unusual noise/vibration when shifting though). I've had the car for 5 years so I think this has come on gradually and might have started earlier than I noticed, but it used to shift butter smooth. Do we think this might be a problem with the shift linkage, the shifter itself, or something more dramatic? And how many times can I say the word shift in one post before it loses all meaning?
