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

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

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

unzip mjpg-streamer-code-182.zip

MJPG-Streamer comes with several plugins, but only a couple of them are needed to stream video according to the method I explained in my previous article. The command below only builds what's needed:

cd mjpg-streamer-code-182/mjpg-streamer

make mjpg_streamer input_file.so output_http.so

I did not discuss installation in the previous article, and that confused many readers. 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

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.

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"

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://:8080.

After you verify that everything is working you can remove the source code:

cd ../../

rm -rf mjpg-streamer-182
