说明：
motion下载地址： http://sourceforge.net/projects/motion/files/motion%20-%203.2/
系统: Ubuntu 12.10开发板：mini2440linux: 2.6.32交叉工具链：4.4.3motion版本：3.2.11.1
对于PC版本的直接apt-get install motion就可以的具体的使用方法参见
这里。
本文主要记录一下ARM版本的编译使用：
1.去上边说明的motion下载地址下载3.2.11.1版本
2.配置命令：./configure --prefix=${PWD}/_install --host=arm-linux --without-ffmpeg
3.接下来就是make 和 make install了。
4.make install后会在_install/bin/目录下产生motion可执行文件，拷贝到开发板上/root/motion目录下，并在同目录中建motion.conf内容如下：
# Minimal motion example config file provided by the# Debian motion package - for basic webcam operation.## You most certainly want to investigate# /usr/share/doc/motion/examples/motion-dist.conf.gz# for further configuration options. Also, refer to the# motion man page and /usr/share/doc/motion/motion_guide.html# for detailed information on configuration options.
daemon off
quiet on
locate on
# You may very well need to change this (check with 'dmesg'# after plugging in your webcam).
videodevice /dev/video0
# Image size in pixels (valid range is camera dependent).
width 320
height 240
framerate 25
quality 85
auto_brightness off
# General threshold level and noise threshold# level (for distinguishing between noise and motion).
threshold_tune off
threshold 4500
noise_level 64
# Initial brightness, contrast, hue (NTSC), and saturation.# 0 = disabled (valid range 0-255).
brightness 0
contrast 0
saturation 0
hue 0
# Encode movies in real-time (install ffmpeg before enabling).
ffmpeg_cap_new on
# Codec to be used by ffmpeg for the video compression.# Supported formats: mpeg4, msmpeg4.
ffmpeg_video_codec msmpeg4
# Target base directory for pictures and films (you may need# to change this (or change its permissions) depending on# which system user runs motion).
target_dir /root/motion/snapshots
# Define a port number (e.g. 8000) to enable the mini-http server.
# 0 = disabled.
webcam_port 8081
# Set to 'off' to allow anybody (not just localhost) to view the# webcam via the mini-http server ( http://hostname:port).
webcam_localhost off
snapshot_interval 1
snapshot_filename snapshot
webcam_quality 50
webcam_maxrate 8
#on_event_start /root/motion/on_motion_detected
#on_event_end /root/motion/on_motion_end
gap 10
5.运行./motion -c motion.conf
6.用chrome浏览器实时监控（360极速，世界之窗测试不可以）
