Install a Camera and a Realtime Stream Server on the Raspberry Pi

A Raspberry Pi with a camera can become a real time stream sever. We can select either
UV4L or mjpg-streamer to transmit its streaming data.

UV4L(User space Video4Linux collection) includes a full-featured Streaming Server component providing a set of solutions for live audio & video streaming, casting/mirroring and conferencing over the web. 

On the other hand, the MJPG-streamer takes JPGs from Linux-UVC compatible webcams, file system or other input plugins and streams them as M-JPEG via HTTP to web browsers, VLC and other software.

We can install both on the Raspberry Pi.

First, we connect the Camera bus to the Raspberry Pi board, and the start the raspi-config:

sudo raspi-config

Select item 6 to enable the camera:
6 Enable Camera .......                

Reboot and run tests:

raspistill -o cam.jpg
raspivid -o vid.h264

The image/video window will be shown on the console.

Install MJPEG Stream components:

sudo apt-get update
sudo apt-get install subversion
sudo apt-get install libjpeg8-dev
sudo apt-get install imagemagick
sudo apt-get install libv4l-dev

Get mjpg-streamer from svn:

svn co https://svn.code.sf.net/p/mjpg-streamer/code/
cd code/mjpg-streamer
sudo make install

wget http://www.linux-projects.org/listing/uv4l_repo/lrkey.asc && sudo apt-key add ./lrkey.asc
sudo nano /etc/apt/sources.list

Add this line to the file and exit:

deb http://www.linux-projects.org/listing/uv4l_repo/raspbian/ wheezy main

sudo apt-get update
sudo apt-get install uv4l uv4l-raspicam

For autostart service:

sudo apt-get install uv4l-raspicam-extras

sudo reboot

Install uv4l:
sudo pkill uv4l
sudo apt-get update
sudo apt-get install uv4l-uvc
sudo apt-get install uv4l-xscreen
sudo apt-get install uv4l-mjpegstream
sudo apt-get install uv4l-server
sudo reboot

The WebRTC extension for the Streaming Server is also available:
sudo apt-get install uv4l-webrtc
uv4l --auto-video_nr --driver raspicam --encoding mjpeg --server-option '--port=9000' or
uv4l --auto-video_nr --driver raspicam --encoding mjpeg --server-option '--port=9000' --driver raspicam --rotation 180 --width 352 --height 288
Use Browser to link to the uv4l server:    

sudo modprobe bcm2835-v4l2
cd code/mjpg-streamer
./mjpg_streamer -i "./input_uvc.so" -o "./output_http.so -w ./www"

Use Browser to link to the mjpg-streamer:
