Raspberry Pi Camera over Internet with MJPG Streamer

Motion JPG is a video compression format in which each video frame or video sequence is compressed separately as a JPEG image. MJPG-streamer takes JPGs from compatible cameras or other input plugins and streams them as M-JPEG via HTTP to web browsers and other media players.

A. Essentials

Requirements:

Raspberry Pi
Raspberry Pi Camera Module

B. Connect the Camera Module

Raspberry Pi Camera Port Camera connection from both sides

Locate the camera port and connect the camera as shown.
Open the Raspberry Pi Configuration Tool from Preferences on the main menu

Raspberry Pi Camera Enable

Enable the Camera from Interfaces tab if Disabled and Reboot the Pi.

C. Installing Dependencies

Install dev version of libjpeg:

sudo apt-get install libjpeg62-turbo-dev

Install make:

sudo apt-get install cmake

D. Installing MJPG Streamer

Download mjpg-streamer with raspicam plugin:

git clone https://github.com/jacksonliam/mjpg-streamer.git ~/mjpg-streamer

Change directory:

 cd ~/mjpg-streamer/mjpg-streamer-experimental

Compile:

 make clean all

Replace old jpg-streamer:

sudo rm -rf /opt/mjpg-streamer
sudo mv ~/mjpg-streamer/mjpg-streamer-experimental /opt/mjpg-streamer
sudo rm -rf ~/mjpg-streamer

E. Start Streaming

To Begin streaming type:

 LD_LIBRARY_PATH=/opt/mjpg-streamer/ /opt/mjpg-streamer/mjpg_streamer -i "input_raspicam.so -fps 15 -q 50 -x 640 -y 480" -o "output_http.so -p 9000 -w /opt/mjpg-streamer/www"

You can change the above parameters

Parameter	Point	Details
-i	input	input parameters
-o	output	output parameters
-fps	framerate	video framerate, default 5 frame/sec
-q	quality	set JPEG quality 0-100, default 85
-x	width/x-axis	width of frame capture, default 640
-y	height/y-axis	height of frame capture, default 480
-p	HTTP port	TCP port for this HTTP server
-w	web page folder	folder that contains webpages

You will see something like this

MJPG Streamer Version.: 2.0

i: fps.............: 15

i: resolution........: 640 x 480

i: camera parameters..............:

Sharpness 0, Contrast 0, Brightness 50, Saturation 0,

Exposure Mode 'auto', AWB Mode 'auto',

Image Effect 'none', Metering Mode 'average',

Colour Effect Enabled No with U = 128, V = 128

Rotation 0, hflip No, flip No

www-folder-path...: /opt/mjpg-streamer/www/

HTTP TCP port.....: 9000

username:password.: disabled

Encoder Buffer Size 81920

Now type this url in your browser http://localhost:9000/stream.html to view the streamed output locally or type the IP address of Raspberry Pi with the port like http://<IP-address>:9000/stream.html to watch from another computer/device in your network.

Find IP address:

To find IP address there are many ways, one of them is by typing ifconfig in terminal

sudo ifconfig

It will be something like this

eth0      Link encap:Ethernet  HWaddr 09:00:12:90:e3:e5  
          inet addr:192.168.1.29 Bcast:192.168.1.255  Mask:255.255.255.0

          RX bytes:115886055 (110.5 MiB)  TX bytes:83286188 (79.4 MiB)

In this case, 192.168.1.29 is the IP-address You should enter the address like http://192.168.1.29:9000/stream.html in your browser to view streaming.

F. Stop Streaming

To stop streaming type:

kill -9 'pidof mjpg_streamer'
