Create time-lapse videos with my Foscam FI8910W camera.

timelapse.sh

#!/bin/sh

# This script will make a timelapse video from a Foscam FI8910W camera by
# downloading the snapshot image every 2 seconds, watermarking it with the
# current time, and then using ffmpeg on those images to make the movie.
#
# Capturing stops on Ctrl-C or 10 hours of elapsed time.

# Note:  This was put together hastily and I'm sure the ffmpeg
# options or framerate could be improved.

# Example: ~/timelapse/timelapse.sh ~/timelapse/results/$(date +%m%d%Y)
