MJPG-Streamer推流,将摄像头图像推送到http网页,

莫龙丹MJPG-Streamer推流，将摄像头图像推送到http⽹页，mjpeg推流，将摄像头推送到http⽹页

⼀、⼯具准备

1. Linux系统

2. usb摄像头

⼆、安装MJPG-Streamer

依赖的库和⼯具：

#库

sudo apt-get install libjpeg8-dev #JPEG⽀持库（图像相关）

sudo apt-get install libv4l-dev #4l是⼩写"L"（底层摄像头驱动的上层应⽤库）

#⼯具

#sudo apt-get install cmake #下载编译⼯具（⼀般都有，没有需要下载）

#sudo apt-get install git #（⼀般都有，没有需要下载）

安装与运⾏

# ⽅式包含但不限于以下两种

关于桥的成语# ⽅式⼀ git

# pi@raspberrypi:~ $git clone e.coding/fivecc/mjpg-streamer/mjpg-streamer.git

# ⽅式⼆ wget

pi@raspberrypi:~ $wget github/Five-great/mjpg-streamer/archive/master.zip

猎毒人阿香

pi@raspberrypi:~ $unzip master.zip

#两种⽅式实现的效果⼤致相同

pi@raspberrypi:~ $ cd mjpg-* # 进⼊mjpg-streamer-master⽂件夹

pi@raspberrypi:~/mjpg-streamer-master $ cd mjpg-* # 进⼊mjpg-streamer-experimental⽂件夹

pi@raspberrypi:~/mjpg-streamer-master/mjpg-streamer-experimental $ make #编译

pi@raspberrypi:~/mjpg-streamer-master/mjpg-streamer-experimental $ sudo make install #安装

# ⾄此安装完毕

# 接下来就可以运⾏

pi@raspberrypi: ~ $ ./mjpg_streamer -i "./input_uvc.so -n -r 1920x1080 " -o "./output_http.so -w ./www"

运⾏之后我们就可以在服务器的8080端⼝看到我们的摄像头啦

运⾏参数

mjpg_streamer

# mjpg_streamer本⾝只有两个主要参数

# -i：指定⽣成动态库

# input_uvc.so：⽤来处理输⼊的数据

# -o：指定⽣成另外⼀个动态库

# output_http.so：⽤来处理输出的数据，⽤来给到浏览器

# 注意：MJPG-Streamer还有⼀个插件叫做output_rtsp.so；其实它是浪得虚名，它并不能把我们的输⼊转换成rtsp协议输出input_uvc.so

[-d | --device ].......: video device to open (your camera)

[-r | --resolution ]...: the resolution of the video device,

can be one of the following strings:

QQVGA QCIF CGA QVGA CIF PAL

VGA SVGA XGA HD SXGA UXGA

FHD

or a custom value like the following

example: 640x480

[-f | --fps ]..........: frames per second

(camera may coerce to different value)

[-q | --quality ] .....: set quality of JPEG encoding

[-m | --minimum_size ].: drop frames smaller then this limit, useful

if the webcam produces small-sized garbage frames

may happen under low light conditions

[-e | --every_frame ]..: drop all frames except numbered

[-n | --no_dynctrl ]...: do not initalize dynctrls of Linux-UVC driver

[-l | --led ]..........: switch the LED "on", "off", let it "blink" or leave

it up to the driver using the value "auto"

[-t | --tvnorm ] ......: set TV-Norm pal, ntsc or secam

[-u | --uyvy ] ........: Use UYVY format, default: MJPEG (uses more cpu power) [-y | --yuv ] ........: Use YUV format, default: MJPEG (uses more cpu power) [-fourcc ] ............: Use FOURCC codec 'argopt',

currently supported codecs are: RGB24, RGBP

[-timestamp ]..........: Populate frame timestamp with system time

[-softfps] ............: Drop frames to try and achieve this fps

set your camera to its maximum fps to avoid stuttering

[-timeout] ............: Timeout for device querying (seconds)

[-dv_timings] .........: Enable DV timings queriyng and events processing output_http.so
