A long time ago, I posted on OLPC News Forum about how to make your XO-1 take and display an image with gstreamer and the boa web server. You can take and display an image from the XO-1's camera via any browser on the LAN. These instructions are mostly still valid for the XO-1.
http://web.archive.org/web/20111128021343/http://www.olpcnews.com/forum/index.php?topic=4710.0 But for the XSCE on an XO 1.5, 1.75 or 4? Apache makes things a little more difficult to configure. So let's just see what to do, then. As root, create this file: -bash-4.2# cat /var/www/cgi-bin/webcam.cgi #!/bin/sh # CGI script to take and display an on-demand image echo "Content-type: text/html" echo echo "<html><head><title>A Picture from the XO XSCE Webcam</title><body>" echo "<h1>Here's a Real Time image from the XO XSCE Webcam</h1>" echo "<b>" gst-launch-0.10 v4l2src ! ffmpegcolorspace ! pngenc ! filesink location=/var/www/html/images/webcam.png > /dev/null echo "<br />" echo "<IMG SRC="../images/webcam.png">" echo "<br />" echo "<h2>Refresh this page to take another picture</h2>" echo "</b></body></html>" chmod +x webcam.cgi Still as root, Put apache into the video and audio groups in /etc/groups: -bash-4.2# cat /etc/group |grep apache video:x:39:olpc,apache audio:x:63:olpc,apache mkdir /var/www/html/images and then: chown apache:apache /var/www/html/images Reboot. Then go to http://whatever your XSCE's IP is/webcam.cgi and it automagically takes and displays a picture of what your XSCE XO is pointed at. Then hit F5 to refresh as needed for new pictures.
