I left for the weekend, and left my dog at home (he has a doggy door and an auto food\/water thing, he's ok). I leave a webcam on so I can check on him; the way I have it set up is that I want a picture copied to my public dropbox folder then embedded in an html page, so I can check on him from anywhere. Also, my family\/friends like to look in on him.<\/p>\r\n
To make this work, the dependencies are dropbox, fswebcam, and cheese. fswebcam does the actual picture capturing, cheese is used to auto-calibrate the camera (you can set settings with fswebcam, but it's a pain...I find if you open cheese for 10 seconds then kill it every 30 minutes, its auto-adjust sticks and works great). Here's my script, called autocam.sh:<\/p>\r\n recal) *) This is then called using the following cronjobs:<\/p>\r\n Boom, works great!<\/p>\r\n So, then to turn it into a timelapse, I cd into the ~\/Pictures\/RygelWatch folder and run:<\/p>\r\n I then build the video using mencoder with the following command:<\/p>\r\n This works great! Finally, I opened that up in openshot, polished it a bit, and submitted it to youtube:<\/p>\r\n#!\/bin\/bash
\ncase \"$1\" in<\/p>\n
\n cheese &
\n sleep 10s
\n killall cheese
