The package motion is not available in the OpenWrt repositories. http://www.lavrsen.dk/foswiki/bin/view/Motion/WebHome

opkg install kmod-video-uvc mjpg-streamer

→/etc/config/mjpg-streamer

• start on boot

  /etc/init.d/mjpg-streamer enable
  

• start mjpg-streamer right now

  /etc/init.d/mjpg-streamer start
  

Now open the URL http://192.168.1.1:8080/ in the Firefox browser or VLC and watch the MJPEG stream. In other browsers, scripts, etc., you can use http://192.168.1.1:8080?action=snapshot for taking one image or http://192.168.1.1:8080?action=stream for stream of images.

[This command needed after my installation of trunk onto a WR703n as of 2012/09/24:

mjpg_streamer -i "input_uvc.so -d /dev/video0 -r 640x480" -o "output_http.so -p 8080 -w /www/webcam"&

]

• Download a package located here and unpack it into /www/webcam_www directory.
• Edit /etc/init.d/mjpg-streamer - find this line in function start():

[ $enabled -gt 0 -a -c $device ] && sleep 3 && $SSD -S -m -p $PIDF -q -x $PROG -- --input "input_uvc.so --device $device --fps $fps --resolution $resolution" --output "output_http.so --port $port" &

and add -w /www/webcam_www behind –output "output_http.so. Now it should look like this:

[ $enabled -gt 0 -a -c $device ] && sleep 3 && $SSD -S -m -p $PIDF -q -x $PROG -- --input "input_uvc.so --device $device --fps $fps --resolution $resolution" --output "output_http.so -w /www/webcam_www --port $port" &

• Now restart mjpg-streamer and open the URL http://192.168.1.1:8080/ in your web browser.

Here is a writeup of using openWrt for a pan and tilt camera. The devices were NSLU2 for openWrt and Picaxe for microcontroller, but the idea is the same with arduino as micro and other openWrt devices:

Grey day today here in Nova Scotia, you can see at http://www.lyzby.com/cam.html

If the control page doesn't contain any of the controls, edit the file /etc/init.d/mjpg-streamer and replace these lines

service_start /usr/bin/mjpg_streamer --input "input_uvc.so \
                --device $device --fps $fps --resolution $resolution" \           
                --output "output_http.so --www $www --port $port"

by (on a single line )

service_start /usr/bin/mjpg_streamer --input "input_uvc.so --device $device --fps $fps --resolution $resolution" --output "output_http.so --www $www --port $port"

The command mjpg_streamer -h give you usage information and examples.

The package uvc-streamer is no longer in the OpenWrt repositories.
