Asus Eee PC netbook tip / howto: Using the webcam | (Nederlandse versie) |
Note: this tip applies to an Eee running
Eeedora (or Fedora), if you're
still running the original Linux distribution supplied
by Asus, your mileage may vary.
The webcam is available at /dev/video0.
It is enabled at startup with this line in /etc/rc.local: capturing single shots A nice tool to capture shots from the camera is fswebcam (run yum install fswebcam as root), for example: fswebcam -r 640x480 --jpeg 85 -D 1 shot.jpg At higher resolutions you have to skip a few frames before the exposure "settles" (also this example saves to PNG at maximum compression instead of to JPEG): fswebcam -r 1280x1024 --png 9 -D 1 -S 3 --save shot.png capturing single shots while watching
For this you can use mplayer (to install, run yum install mplayer
as root, more elaborate installation instructions
are here): The screenshot filter is there so you can save camera shots to PNG files: press 's' while mplayer is running. ucview This is a nice GUI driven tool that allows you to do, among other things, time-lapse recordings (yum install ucview to install).
