Actually trotting and walking burn more calories than cantering, cantering is a cardio exercise, it winds them. I am not much help, but maybe include gallop sets in your work? If that isn't possible, canter sets and trot sets. Make up a conditioning schedule for him (search them Online) and see if that helps.
He might just be mentally tired, can you take him for a trail ride every week so? Or maybe more turnout - or just hand walking or grazing if there is some grass at your stable if more turnout isn't possible. I too live in Caly, it sucks how little turnout there can be. Does he live in a box stall or a mare motel type thing? How often is he fed? He might be happier with free choice hay (in a slowfeeder- small mesh hay net), especially if he is only fed twice a day.
After watching the video, he looks like he might be doing something funny with his hind end. Drifting out a bit in the corners and not reaching under him much, just doesn't quite look right over the jumps. Obviously you would know him much better than I, this just could be his way of doing things.
