it's a mix of c and objective c. i'm taking video from a contour cam and parsing the data from the corresponding tcx/fit file. overlay rendered using opengl and video export using quicktime. i haven't used dashcam but it's something along those lines. i had a moral objection to paying for something i could easily do myself
I'm still not getting it. Is there a display while you're riding, or is this a post-ride visualization only?
