./configure
You can add the parameter ./configure --help to get help on the different switches.
This is walk through of the options.
Attention!
If you have run make before, you should run a make clean before running make again. This cleans out all the object files that were generated the previous time you ran make. If you do not run make clean first before you rebuild Motion you may not get the additional feature included. For example: If you built Motion without ffmpeg support and then add it later - and rebuild Motion without running make clean first - the ffmpeg feature does not get compiled into the Motion binary.
First time you build motion run ./configure, make, make install. If you need to build it again (to run with different configure options) run ./configure, make clean, make, make install.
make install simply copies all the nice files that were generated during the compilation/linking that make did.
Makes the directories (if they do not already exist)(path shown are the defaults): /usr/local/bin, usr/local/man/man1, /usr/local/etc, /usr/local/share/doc/motion-3.2.X, and /usr/local/share/doc/examples/motion-3.2.X.
Copies the following files from the base motion directory (assuming the default PREFIX /usr/local was used when running configure - otherwise adjust to the actuals you chose) make uninstall
And delete the base installation directory in /usr/local and any link pointing to it. If you have forgotten where you installed it or someone else did it for you, simply search for the files and directories starting with motion. If the filenames and the directories match the names described in the "Make Install" section of this document, you can safely delete them.
make, make install and make uninstall has already been described above.
make clean before you run make if you change the configuration (like adding features such as ffmpeg) and rebuild motion.
-c pathname Motion will expect the config file to be as specified. When you specify the config file on the command line with -c you can call it anything.
If you do not specify -c or the filename you give Motion does not exist, Motion will search for the configuration file called 'motion.conf' in the following order:
In Motion 3.2.1 and forward most command line options have been removed and replaced them by an option to specify location to motion.conf and a few options related to setting up motion. There are now only few command line options left and they are basically all new.

This feature is introduced in Motion 3.2.7
Round Robin is not relevant for Network cameras or standard USB web cameras. The Round Robin feature is used with video capture cards which have multiple inputs per video chip.
Note that round robin is not the ideal way to run multiple cameras. When the capture card changes input it takes a little while before the decoder chip has syncronized to the new camera. You can improve this if you have expensive cameras with a syncronize input. Only one camera can be decoded at a time so if you have 4 cameras connected 3 of the camera threads will need to wait for their turn. The fact that cameras have to take turns and the fact that you have to skip a few frames after each turn dramatically lowers the possible framerate. You can get a high framerate by viewing each camera for a long time. But then you may miss the action on one of the inactive cameras. If you can affort it avoid Round Robin and buy the more expensive type of capture cards that has one decoder chip per input. If you only need 2 or 3 cameras you can also simply put 2 or 3 cheap TV cards in the computer. Linux has no problem working with multiple TV cards.
This feature was seriously broken until Motion 3.2.4
rotate option, note that the mask is applied after the rotation.
Detailed Description
The mask file must be a pgm format image file (portable gray map). Note that you must choose the BINARY format.
The feature is simple. Create an image of exact the same size as the ones you get from your video device (camera). Make a purely white picture and paint the areas that you want to mask out black. You can also make gray areas where you want to lower the sensitivity to motion. Normally you will stick to pure black and white.
One easy method for generating the mask file is as follows.
You can just take a motion captured picture, edit it with black and white for the mask and save it as a pgm file.
If you cannot save in this format save as a grayscale jpg and then you can convert it to pgm format with
djpeg -grayscale -pnm [inputfile] > mask.pgm
(assuming you have djpeg installed - part of the jpeg lib package).
Note that the mask file option masks off the detection of motion. The entire picture is still shown on the picture. This means that you cannot use the feature to mask off an area that you do not want people to see.
Below are an example of a webcam picture and a mask file to prevent the detection cars in the street.
Normal picture. Notice the street is visible through the hedge.

From motion 3.2.7 this feature has been removed because it was in practical a useless feature. It prevented saving more than one picture per minimum_gap seconds but the capturing and motion detect was still run at full framerate loading the CPU heavily. From 3.2.7 a new feature called minimum_frame_time has been introduced which lower the capture rate. So it gives the same effect as minimum_gap did but additionally lower the CPU load significantly.
cd /usr/local/ffmpeg ./configure --enable-shared make make installThis creates the
libavcodec.so and libavformat.so libraries under /usr/local/lib and header files under /usr/local/include/ffmpeg.
You probably need to do one more step.
Make sure you have 'root' privileges for the next steps.
Open the file /etc/ld.so.conf in your favorite text editor.
Add this line of text if it is not already there - otherwise go to the next step (ldconfig).
/usr/local/lib
Run the command ldconfig.
Motion should now be able to find the shared libraries for ffmpeg (libavcodec.so and libavformat.so) in /usr/local/lib.
You can also find a pre-compiled binary package (e.g. rpm or deb) and install this. Normally an rpm will place the libavcodec.so under /usr/lib.
There are various RPMs available from different repositories. Some need additional RPMs that are actually not needed by Motion but need to be installed to satisfy dependencies. The editor has tried different RPMs of ffmpeg-0.4.8 and they all seem to work.
Motion then need to be built by running ./configure, make and make install.
(Note that with earlier versions of motion you had to specify the location of libavcodec. Now configure searches for the shared library in /usr/lib and /usr/local/lib by default.)
Note that if you install ffmpeg from source and already have ffmpeg installed from an RPM, the Motion configure may very well find the binary library from the rpm instead of the sources. Make sure to uninstall any old ffmpeg RPMs before you install ffmpeg from sources.
These are the config file options related to ffmpeg.

text_event feature is special in that it defines the conversion specifier %C which can be used both for text display and for filenames.
target_dir is the target directory for all snapshots, motion images and normal images. The default is the current working directory (current working directory of the terminal from which motion was started). You will normally always want to specify this parameter.
Note that the options snapshot_filename, jpeg_filename, ffmpeg_filename, and timelapse_filename all allow specifying directories by using '/' in the filename. These will all be relative to target_dir. This means in principle that you can specify target_dir as '/' and be 100% flexible. It also means that Motion can write files all over your harddisk if you make a mistake. It is recommended to specify the target_dir as deep or detailed as possible for this reason. And note that targer_dir does not allow conversion specifiers.
The conversion specifier %C which is defined by the option text_event is interesting in connection with filenames because it can be used to create files and directories for each event in a very flexible way.
The convertion specifier %t (thread/camera number) is also very useful. Here is an example of filename definitions in motion.conf:
target_dir /usr/local/webcam snapshot_filename cam%t/%v-%Y%m%d%H%M%S-snapshot jpeg_filename cam%t/%v-%Y%m%d%H%M%S-%q ffmpeg_filename cam%t/%v-%Y%m%d%H%M%S timelapse_filename cam%t/%Y%m%d%H-timelapseThe smart thing is that this defines the filename of all your camera threads in motion.conf so you do not need to specify target dir and filenames in the thread config files. In the above example an mpegfile for camera thread 3 will be saved as a filename similar to
/usr/local/webcam/cam3/28-20051128130840.avi
NOTE: Unless you use the minimum_gap option to limit the number of shots to less then one per second - you must use the frame modifier %q as part of the jpeg_filename. Otherwise the pictures saved within the same second will overwrite each other. The %q in jpeg_filename ensures that each jpeg (or ppm) picture saved gets a unique filename.
Security Warning! Note that the flexibility of this feature also means you have to pay attention to the following. This option was renamed to movie_filename in 3.2.5 to enable better integration of alternative movie libraries to the current ffmpeg solution.
This option was renamed from ffmpeg_filename to movie_filename in Motion 3.2.5.
Default value is equivalent to legacy 'oldlayout' option
For Motion 3.0 compatible mode (directories based on date and time) choose: %Y/%m/%d/%H%M%S
File extension .mpg or .avi is automatically added so do not include this.
This option uses conversion specifiers which are codes that start by % and then a letter. The conversion specifiers used has the same function as for the C function strftime (3). The most commonly used are: text_event, text_left, text_right, sql_query, snapshot_filename, jpeg_filename, ffmpeg_filename, timelapse_filename, on_event_start, on_event_end, on_picture_save, on_movie_start, on_movie_end, and on_motion_detected.
In text_left and text_right you can additionally use '\n' for new line.

ppm is set to off. (I.e. saved images are jpeg images).
The webcam_maxrate and webcam_quality options are important to limit the load on your server and link. Don't set them too high unless you only use it on the localhost or on an internal LAN. The option webcam_quality is equivalent to the quality level for jpeg pictures.
The webcam_limit option prevents people from loading your Network connection by streaming for hours and hours. The options defines the number of picture frames sent as mjpeg Motion will allow without re-connecting (e.g. clicking refresh in the browser).
The option webcam_localhost is a security feature. When enabled you can only access the webserver on the same machine as Motion is running on. If you want to present a live webcam on your web site this feature must be disabled.
The webserver generates a stream in "multipart jpeg" format (mjpeg). You cannot watch the stream with most browsers. Only certain versions of Netscape works. Mozilla and Firefox brosers can view the mjpeg stream but you often have to refresh the page once to get the streaming going. Internet Explorer cannot show the mjpeg stream. For public viewing this is not very useful. There exists a java applet called Cambozola which enabled any Java capable browser to show the stream. To enable the feature to a broad audience you should use this applet or similar.
To use the webcam feature with Cambozola is actually very simple.
1. Create a html page in which you will want the streamed picture.
2. In the html page include this code
<applet code=com.charliemouse.cambozola.Viewer
archive=cambozola.jar width="320" height="240" style="border-width:1; border-color:gray; border-style:solid;">
<param name=url value="http://www.myurl.com:8081">
</applet>
Where the width and height is the image size of the video stream.
Replace www.myurl.com:8081 by the real url and port number of your choice.
3. In the same directory you place the cambozola.jar file. No need to build the java applet from source. Simply use the applet in the package.
4. Enable the feature in motion.conf.
You can also view the live webcam stream using MPlayer like this:
mplayer -demuxer lavf http://www.myurl.com:8081/stream.mjpgNote that the
stream.mjpg part is important, without it you will get a LAVF_check: no clue about this gibberish! error from libavformat.
These are the special webcam parameters.
0 9 * * * root /usr/bin/lwp-request http://localhost:8080/0/detection/start > /dev/null 0 18 * * * root /usr/bin/lwp-request http://localhost:8080/0/detection/pause > /dev/nullIf you want to use the http remote control from your own software (for example your own PHP front end) you can set the new motion.conf option html_output off. Then Motion answers back with very basic text only and no html around it. A bit like the xmlrpc interface did. To remote control Motion from a web pages you can for example use PHP. In PHP it takes this simple code line to send a remote commend to Motion. Here we pause motion detection for camera 2
readfile('http://localhost:8080/2/detection/pause');
What happened to XMLRPC?
XMLRPC is replaced by a simpler http remote control interface. It is still being worked on but it is absolutely useable now and much nicer to work with than xmlrpc. Another advantage is that you do not need to install xmlrpc libraries. It is all written in standard C.
Security Warning! Note that this feature also means you have to pay attention to the following. quiet is also included in this section.
A redesign of the external commands was due. They were not very easy to understand, not all were flexible enough and some were missing. So a new external command feature set was made for 3.2.1 and on.
This is how the new script commands look like:
| Function | Old Option | New Option | Argument Appended |
|---|---|---|---|
| Start of event (first motion) | execute | on_event_start | None |
| End of event (no motion for gap seconds) | New! | on_event_end | None |
| Picture saved (jpg or ppm) | onsave | on_picture_save | Filename of picture |
| Movie starts (mpeg file opened) | onmpeg | on_movie_start | Filename of movie |
| Movie ends (mpeg file closed) | onffmpegclose | on_movie_end | Filename of movie |
| Motion detected (each single frame with Motion detected) | New! | on_motion_detected | None |
Security Warning! Note that this feature also means you have to pay attention to the following. #!/bin/sh # Motion sample script to send an e-mail at start of an event. # Replaces the former 'mail' option. # Just define this script as 'on_event_start'-script in motion.conf like that: # on_event_start send_mail "%Y-%m-%d %T" #change to suit your needs: #location of 'mail' binary MAIL="/usr/bin/mail" #Destination e-mail address TO="root@localhost" #Subject of the e-mail SUBJECT="Motion detected" #Don't change anything below this line echo -e "This is an automated message generated by motion.\n\nMotion detected: $1\n\n" | $MAIL -s "$SUBJECT" $TO

CREATE TABLE security (camera int, filename char(80) not null, frame int, file_type int, time_stamp timestamp(14), text_event timestamp(14));
If you choose to use text_event for a non-timestamp value you can instead define something like.
CREATE TABLE security (camera int, filename char(80) not null, frame int, file_type int, time_stamp timestamp(14), text_event char(40));
Remember to update grant table to give access to the mysql username you choose for motion.
It would be too much to go into detail about how to setup and use MySQL. After all this is a guide about Motion. However here are some hints and links.
Setting Up a MySQL Based Website - A beginners guide from Linux Planet.
Webmonkey PHP/!MySQL tutorial - Entertaining and easy to read.
The phpMyAdmin homepage. The best and simplest tool to use MySQL (editors opinion). Requires Apache/PHP.
The options for MySQL
mknod /dev/video4 c 81 4 mknod /dev/video5 c 81 5 mknod /dev/video6 c 81 6 mknod /dev/video7 c 81 7 mknod /dev/video8 c 81 8 mknod /dev/video9 c 81 9 mknod /dev/video10 c 81 10 mknod /dev/video11 c 81 11Note that the video device number is the same as the last parameter given on each line. You may need to set the ownership and permissions (chown and chmod) to be the same as the video devices that were already there. Now you need to install the video loopback device. Download the latest video4linux loopback device . Place the file in a place of your own choice. Untar and uncompress the file to the place you want the program installed. Editor recommends /usr/local/vloopback.
cd /usr/local
tar -xvzf /path/to/vloopback-1.1-rc1.tar.gz
You now have a directory called vloopback-1.1-rc1. You can rename it to vloopback (mv vloopback-1.1-rc1 vloopback). I recommend creating a symbolic link to the current version. This way you can more easily experiment with different versions simply by changing the link.
ln -s vloopback-1.1-rc1 vloopback
Now change to the new directory
cd vloopback
Build the code
make
There is a good chance that the make will not work and give you a long list of errors. To run make the following must be available on you machine. ln -s /usr/src/linux-2.4.18-4 /usr/src/linux
#include <linux/malloc.h>
with the line
#include <linux/slab.h>
Install the code you built as a Kernel module. There are two options: pipes should be set to the number of video loopbacks that you want. Probably one for each camera. The dev_offset defines which video device number will be the first. If dev_offset is not defined the vloopback module will install itself from the first available video device. If you want the cameras to be assigned to the lower video device numbers you must either load vloopback after loading the video device modules OR use the dev_offset option when loading vloopback. Vloopback then installs itself in the sequence input 0, output 0, input 1, output 1, input 2, output 2 etc. Here is shown the command for our example of 4 cameras and 4 loopback devices and the first loopback device offset to /dev/video4.
/sbin/insmod /usr/local/vloopback/vloopback.o pipes=4 dev_offset=4
When you run the command you may get a warning about tainting the Kernel. Just ignore this.
You can choose to copy the vloopback.o file into a directory in the /lib/modules tree where the insmod/modprobe programs are already looking for modules. Then the command gets simpler (/sbin/insmod vloopback pipes=.....).
If you want the loopback device to load during boot, you can place the call in one of the bootup scripts such as /etc/rc.d/rc.local. Vloopback should be loaded before you start motion.
To activate the vloopback device in motion set the 'video_pipe' option in the motion.conf file. You can also view the special motion pictures where you see the changed pixels by setting the option 'motion_video_pipe' in motion.conf. When setting the video_pipe and/or motion_video_pipe options either specify the input device as e.g. /dev/video4. You can also set the parameter to '-' which means that motion will find the first vacant video loopback device input. If you have more than one camera you may want to control which loopback device each thread uses. Then you need to define the specific device name in motion.conf for the first camera and in each thread config file for the other cameras. If you set the video_pipe parameter to '-' in the motion.conf file and not setting it in the thread config files, motion automatically assign video devices in the same sequence as the threads are loaded. You can combine both video_pipe and motion_video_pipe but then naturally you will need twice as many pipes.
De-activating should be done with this command
/sbin/modprobe -r vloopback
