#
#  ### Program for making timelapse out of webcam images ###
#
#  usage: $ ./webcam.py 3 2d webcamImages http://webcam.com/current.jpg
#
#  3: interval between images in seconds
#  2d: How long to keep recording (X d/h/m)
#  webcamImages: Name of the folder to save images. Will be created in getcwd()
#  http://webcam.com/current.jpg: URL of the current image
#
#  After the specified time has elapsed, a video will be created at 60 fps.
#  If you want to make another video at another framerate, use video.py.
#
#  Some webcam urls to try:

#  UPDATE
#  ======
#  A simpler way to get images is the following:
#  while true; do echo $URL; sleep 2; done | xargs -n1 -P8 -I{} bash -c 'date +%s; wget {} -O $(date +%s).jpeg -a /dev/null;'
# Which has the advantage that if loading an image takes longer than the planned time between
# downloads, xargs makes the next request while the previous download is still running.
# (It's up to the server if it can anwer requests that fast)
