How to build and run MJPG-Streamer on the Raspberry Pi

1. Install build dependencies

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

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

4. Unzip the MJPG-Streamer source code

unzip mjpg-streamer-code-182.zip

5. Build MJPG-Streamer

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

6. Install MJPG-Streamer

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

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://:8080.

10. Cleanup

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

cd ../../

rm -rf mjpg-streamer-182
