Issues with latest Camera Firmware
(Still on-going May 2014 - Silvan as been unable to find the issue so far as no errors are being reported)

If you find that videos or photos are freezing, or perhaps motion isn't recording video properly, try going back to an older firmware using this command:

Updating to the latest version
First, update your firmware because RaspiMJPEG will utilise the latest camera firmware: Then update the code (git pull and stop raspimjpeg are now run when using the install option):

The Config File
Thanks to the amazing hard work by Silvan Melchior, RaspiMJPEG now uses a config file to set various parameters on starting the RPi Can Web Interface.

The release update which includes an example of the config file can be found here: http://www.raspberrypi.org/phpBB3/viewtopic.php?p=524707#p524707

A few examples on how to set variables can be found below.

Changing the Field of View
Follow this tutorial to start a different view automatically during boot:

There are three different preview modes available which are set by changing the resolution of the video_width and video_height options in the # Video Options section.

The view along with resolution is shown below: e.g. to set 4:3 full FOV:

If using motion you need to edit motion.conf adding the directive:

Configure Timelapse
Timelapse is now built into RaspiMJPEG

Use nginx web server instead of Apache
This could cause difficulties when silvanmelchior releases an update because it would try to install Apache again

View video stream on an iDevice / Smartphone
Credit goes to Oke for the original post. A few more tweaks added for iPhone app. http://www.raspberrypi.org/phpBB3/viewtopic.php?p=507756#p507756


 * On the Pi, run:


 * Download "IP Cam View Pro" (I used IP Cam View Lite on the iPhone - can upgrade to Pro)
 * Select the menu icon
 * Press Manage Cameras
 * Select Add Camera then Generic URL
 * Give your cam a name
 * For Type choose Generic Video URL
 * Enter your URL, e.g. http://192.168.0.1:80/cam.jpg
 * Press Test
 * If it works, press Save

Embed live-preview in own homepage

 * Navigate to /var/www
 * Remove all files except cam_pic.php, script_min.js and FIFO
 * Copy your own homepage into /var/www
 * Change your index.html/php: Add script_min.js ( in header)
 * Change your index.html/php: Add [i]onload="setTimeout('init;', 100);"[/i] to body
 * Change your index.html/php: Add  at the place where you want the live-preview.

The size can be changed either as parameter in /etc/rc.local or with CSS. To add further features (change settings, record images/videos), study the existing homepage.

If you've mounted a network share to something other than /var/www/media, such as /mnt/myshare, you can bind the two together using this command:

Pi-Pan and Pi-Light
Information about Pi-Pan and Pi-Light: http://www.openelectrons.com/Pi-Pan‎

Needed Hardware for this addition:
 * Pi-Pan (OpenElectrons)
 * Pi-Light (OpenElectrons)
 * Pi-Case to mount Pi-Pan recommended (e.g. OpenElectrons)

With these code-changes and additions, it's possible to control Pi-Pan and Pi-Light from the RPi Cam Web Interface. Just follow these steps:


 * Assembly and install Pi-Pan: http://www.openelectrons.com/index.php?module=pagemaster&PAGE_user_op=view_page&PAGE_id=20
 * Add the file "pipan_pipe.py" to the pipan-files with the following content:


 * Navigate to "/var/www" and add a named pipe with the following commands:


 * Edit "/etc/rc.local": add the following line below the raspimjpeg-command (change the path to the directory where you extracted the pipan-files:


 * Add the file "pipan.php" to "/var/www":


 * Add the file "pipan.js" to "/var/www":


 * Add the following line to "index.html" below " ":


 * Add the following lines to "index.html" below "":


 * Add the following lines to "index.html" below "":

That's it. After rebooting your Pi, you should be able to control Pi-Pan with the new Buttons "Up", "Down", "Left" and "Right" or on the keyboard with "W", "S", "A" and "D". The Pi-Light can be controled in the settings-table or on the keyboard with "F". If you have a touch-device (Android or iOS), you can pan/tilt by dragging the preview-image around and change the Pi-Light by clicking on the preview. To change the minimum/maximum pan/tilt angles, edit the settings in /var/www/pipan.php.

Overlay/Composite two images together
One way to add an image over the top of another is with ImageMagick. I've constructed a crude example below, and it works! But it bogs down the refresh rate, drives the load level to 1.5 and is barely acceptable. I'd like to toggle it on/off with a new button, and improve it's performance, so please edit this article better.
