Wall PapersTo me the coolest thing one can do with a 24 hour available internet connection is to continously download webcam shots from different parts of the world. Save the series of images locally and produce a video out of them. Pretty cool actually. You can have a look at my first sequence.
The webcam is here
I wrote a 10 line python script to grab the photos and by a simple mencoder command, I create the video.
The python script:
#!/usr/bin/python
import urllib, time, sys
i = 0
url = sys.argv[1]
duration = int(sys.argv[2])
while 1:
j = str(i).zfill(6)
filename = "webshot%s.jpg"%j
urllib.urlretrieve(url, filename)
time.sleep(duration)
i = i + 1
This work by:
./webcamer.py URL seconds
The only issue with this script is that it doesn't check if the downloaded image is an undamaged jpeg. As you will find that sometimes the downloading of the image will happen at the same time it is being uploaded. However, this is not very frequent. I resolve them manually.
The mencoder command:
mencoder "mf://*.jpg" -mf fps=25 -o output.avi -ovc lavc
Ah, BTW I think those stop motion sequences could really be a good source of video for VJ's. They can be looped, ping ponged etc..
One more tip, try starting the sequence by night. This way when they loop you will not notice a change in the cloud pattern.
