Creating a timelapse in Linux

Kvisle — Fri, 19 Aug 2011 14:30:14 +0000

Hello,

I’ve written a couple of scripts for making timelapses in Linux. It’s fairly simple stuff;

Create a screenshot every 15th second by running the following script in a terminal;

#!/bin/bash


# Takes a screenshot of my second monitor every 15 seconds

# Only have one monitor? Drop the -crop part ...
mkdir ~/img
while [ 1 ]; do

#       Uncomment the line below if you only want timelapse of your second monitor, and both monitors are 1680x1050 big.

#	import -window root -crop 1680x1050+1680+0 ~/img/LD21-$(date +%y%m%d-%H%M%S).jpg

import -window root ~/img/LD21-$(date +%y%m%d-%H%M%S).jpg sleep 15 done

(The script is interrupted by pressing CTRL+C)

Then encoding the images can be done using mencoder, like this;

mencoder mf://*.jpg -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi

If you want audio, add ‘-audiofile somefile.mp3′.

Hurray!

How to submit an Entry

So, you’re done now and want to submit an entry?

Here is what you do.

Create an account (if you haven’t already, click here)
Make a post (click here)
Add the tag “Final” to your post (Instructions how)
Upload a single screen-shot to the blog (Instructions how)
Provide download link(s) to your file(s) (Windows Binary, Source, etc)

NOTE: It seems uploading zip files to the blog isn’t allowed with stock permissions set up. Oh well, we’ll have to go with the old way of submitting entries (i.e. link a zip file). Maybe next time.

Moving forward, we’d prefer that you upload your entries to the blog. You’re more than welcome to mirror them on your local site, but at least this way we have a 2nd copy. If your entry is especially large (50 MB+), consider uploading to the blog as a last resort (i.e. you don’t have your own web space).

Images can be named whatever, but we’d suggest entry uploads be named as follows.

UserName_LD??_MyCoolEntryName.EXT

UserName – Your name on the forum (i.e. PoV)
LD?? – The current competition (i.e. LD14, MiniLD09)
MyCoolEntryName – A name for your entry (i.e. MyGame02)
EXT – Whatever the file type is (i.e. zip, tar.bz2)

For example: PoV_LD00_MurMur2.zip

Following these naming guidelines will help us catalog entries in the future.

~~Flash/Browser Based Entries~~

If your game is a Flash or browser based game, then you can provide a link. This will make it much easier for entrants to play your game, since you can tailor the webpage as you see fit (as providing FTP accounts for everyone sound like too much work to me).

In addition, if you could upload a copy for archival purposes, that would be helpful.

How to set a tag

Tagging your posts is easy.

From inside the WordPress, scroll down past the post box to the “Tags” box.

Enter your tag in the box and click Add.

Easy. If you make a mistake, you can click the X beside the tag to remove it.

Common tags include:

Final – for your final entries
deskphoto – for any pictures of your work environment
motivation – for amusing images in the spirit of the competition
foodphoto – what you ate during a compo. Yes, we’re silly
