| mjpg-streamer | libpthread, libjpeg | 33738 | Streaming application for Linux-UVC compatible webcams |
The package motion is not now available in the OpenWrt repositories. http://www.lavrsen.dk/foswiki/bin/view/Motion/WebHome
opkg install kmod-video-uvc mjpg-streamer mjpg-streamer-input-http mjpg-streamer-input-uvc
Don't forget change option enabled '0' to '1'.
/etc/init.d/mjpg-streamer enable
mjpg-streamer right now/etc/init.d/mjpg-streamer start
NOTE: You will need to edit the mjpeg config to enable the mjpeg streamer. Manually edit the /etc/config/mjpeg-streamer file.
Now open the URL http://192.168.1.1:8080/ in the Firefox browser or VLC and watch the MJPEG stream (the default username/password is “openwrt”/“openwrt”). 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.
mjpeg-streamer fps, CPU load, memory usage, bandwidth at different resolutions:
[ $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" &
The opkg version of mjpg-streamer has no control options for the camera. If you want to control exposure, brightness and other options you'll need to install uvcdynctrl.
Install uvcdynctrl
opkg install uvcdynctrl
List available devices.
/usr/bin/uvcdynctrl -l
List available control options.
/usr/bin/uvcdynctrl -c Listing available controls for device video0: Brightness Contrast Saturation Hue White Balance Temperature, Auto Gamma Power Line Frequency White Balance Temperature Sharpness Backlight Compensation
Create a configuration file based on the current running values.
/usr/bin/uvcdynctrl -W /etc/config/uvcdynctrl
Load a configuration file, which can be edited.
/usr/bin/uvcdynctrl -L /etc/config/uvcdynctrl
The above can be added to /etc/rc.local, via the GUI or command line to load settings required for your camera. I use the above to enable auto exposure and auto white balance which would otherwise be disabled from cold a start.
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.
If your webcam is an uvc supported by V4L but you cannot get an image (white page), you may check that webcam output is not YUV only like output below:
root@OpenWrt:~# v4l2-ctl -V
Format Video Capture:
Width/Height : 320/240
Pixel Format : 'YUYV'
Field : None
Bytes per Line: 640
Size Image : 153600
Colorspace : SRGB
The package uvc-streamer is no longer in the OpenWrt repositories.
