Installing UV4L

UV4L is a userspace webcam driver specifically designed for the Raspberry Pi. It also includes some other features that will be discussed in this chapter. U4VL is custom code that is written and developed by Luca Risolia, who runs the website http://linux-projects.org. We will add his repository to get the UV4L driver:

curl http://www.linux-projects.org/listing/uv4l_repo/lrkey.asc | sudo apt-key add -

Add the following line to /etc/apt/sources.list:

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

Tip

If you have not yet run rpi-update, then it is recommended to do it now. The UV4L driver requires the latest foundation kernels and modules to install properly.

Now we need to update the repository list, and then we can install the UV4L driver. We will do these with the following commands:

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

Tip

The UV4L driver makes it really easy to stream video...
