# Determine the videos that correspond to a game.

# This is done by looking at the creation time for each video (each
# raw video file from the camera) and looking at the time difference
# between consecutive videos. If the time difference is greater
# than some threshold (e.g. 10 minutes), we say this marks the time
# in between two games.
