Overview of this book

There’s no end to what you can do with a Raspberry Pi – it makes a huge range of tech projects possible. This book shows you how to transform it into a multipurpose web server, able to store and manage resources that lets you build some truly innovative and impressive computing creations. You’ll learn how to use your Raspberry Pi 2 to host a website using a range of different languages, host a game server, store files, and run everything from a media center to a cloud network. If you want to take control of your technological world, start building your own server and find out what’s possible with the Raspberry Pi microcomputer. Begin by getting your Pi set up – follow each step as the book shows you how to prepare a network and configure the additional features that you’ll need to build your projects. Once you’ve done this you’ll dig a little deeper and set up your pi as a file server, making sure it’s built for speed using a range of different tools, including Python, Node.js and ASP.NET. Following this the book shows you how to extend your server to allow you to host games, and stream live HD video before customizing it even further to create a fully-fledged media center. It doesn’t stop there however – the book then dives into the exciting world of the Internet of Things (IoT). You’ll learn how to install Windows IoT onto your Raspberry Pi, the operating system that’s driving embedded software projects all around the world. Once you’ve done this you’ll be ready to explore IoT further, as the book shows you how to use your device to host a cloud network that can form the basis of a wider IoT project.

Installing WebRTC


Web Real-Time Communication (WebRTC) is a protocol that allows modern web browsers to establish a peer-to-peer link to exchange data. UV4L uses WebRTC to create a socket to the Raspberry Pi and receive a live H264 video stream, eliminating the need for transcoding and allowing us to watch a high-quality, low-latency video directly in our browser.

To install the WebRTC module for uv4l-server, we just need to issue one command and restart UV4L:

sudo apt-get install uv4l-webrtc 
sudo service uv4l_raspicam restart

WebRTC streaming

Please be aware that UV4L WebRTC streams in an adaptive bitrate and resolution. The bitrate and resolution streamed to the client will adaptively adjust based on the connection quality. This means that any configuration that you have applied will not apply to WebRTC streams, but the overlay will still work. It may also disconnect other streams that do not use WebRTC.
