Doom overlay

Currently uses fitparse and moviepy to extract garmin device data and render an overlay, currently statically set up to fit a 1920x1080 frame size, that displays heart rate, speed, cadence, the space marine face icon that becomes visibly strained above a preset heart rate, distance travelled and elevation gained.

Usage is fairly straightforward:

$ ./ovr.py video.mp4 yyyy-mm-dd-hh-mm-ss.fit --output out.mp4 --fit-start 3 --duration 60 --strain 150

The --fit-start 3 parameter allows you to synchronize start of ride with start of video, --duration 60 renders only the first 60 seconds and --strain 150 tells the program to display a strained facial expression when heart rate is above 150 beats per minute. --output out.mp4 allows you to set output file, which by default is constructed by prepending ovr_ to the original filename.

It looks like this.
