Raspberry Pi – Building the Basic Streamer

1. Install build dependencies

You need to be connected to the internet. The following command installs the three libraries that MJPG-Streamer uses:

$ sudo apt-get install libjpeg8-dev imagemagick libv4l-dev

2. Add missing videodev.h

The videodev.h header file that MJPG-Streamer needs has been replaced with a videodev2.h. To make MJPG-Streamer happy you have to create a symbolic link:

$ sudo ln -s /usr/include/linux/videodev2.h /usr/include/linux/videodev.h

3. Download MJPG-Streamer

The source code for MJPG-Streamer is available at sourceforge.net, but it is tricky to find the direct download link:

$ wget http://sourceforge.net/code-snapshots/svn/m/mj/mjpg-streamer/code/mjpg-streamer-code-182.zip

4. Unzip the MJPG-Streamer source code

The source code download is a compressed zip file. Put the file in your home directory (or a temporary folder, if you prefer) and run the following to extract the files:

$ unzip mjpg-streamer-code-182.zip

5. Build MJPG-Streamer

MJPG-Streamer comes with several plugins – we will build them all

$ cd mjpg-streamer-code-182/mjpg-streamer
$ make

6. Install MJPG-Streamer

Copy the required files to the install dirs. The following commands copy all the needed files into system directories:

$ sudo cp mjpg_streamer /usr/local/bin
$ sudo cp output_http.so input_file.so /usr/local/lib/
$ sudo cp -R www /usr/local/www

7. Start the camera

We are almost there. Now it is time to start the camera module:

$ mkdir /tmp/stream
$ raspistill --nopreview -w 640 -h 480 -q 5 -o /tmp/stream/pic.jpg -tl 100 -t 9999999 -th 0:0:0 &

Of course, you can use different options to raspistill if you like.

8. Start MJPG-Streamer

The camera is now writing images, so all that is left is to start MJPG-Streamer:

LD_LIBRARY_PATH=/usr/local/lib mjpg_streamer -i "input_file.so -f /tmp/stream -n pic.jpg" -o "output_http.so -w /usr/local/www"

9. Watch the Stream!

Now you can connect with your web browser and watch the stream live. If you want to watch from within the same Raspberry Pi you can enter http://localhost:8080 in the browser’s address bar. If you want to watch from another computer in your network use http://<IP-address&gt;:8080.

Pi in The Sky… Stage 1 – The Build Up

The first  part of the Pi in the Sky project is to get your RPI ( Raspberry Pi ) up and running and usable.

Every one follow this tutorial and get the Pi up and running.

next steps will be to add camera and stream software


Adafruit is a really excellent site for everything so Adafruit and Google are your friends…
