Create a Portable Low-Cost Streaming Server Using Raspberry Pi

Innovation in Streaming Media

Thanks to Raspberry Pi, access to extremely affordable Linux-based machines has become much easier. These devices feature various types of GPIO and networking protocols. As the platform has evolved over the years, we've seen increasingly demanding applications, as well as applications that consume very little energy. This project combines all these improvements and implements a media streaming server on a Raspberry Pi, which operates with minimal energy—something that would not have been possible with earlier Pi generations.

One reason this server consumes so little power, about two watts, is that it is based on the Pi Zero 2W. The server runs software called Mini-Pi Media Server, which transforms the Pi into a DLNA server capable of streaming media over a network, specifically via WiFi. Samba is used for file sharing, and Cockpit is included for easy web management. In tests, the server could stream video to four wireless devices simultaneously, all powered by a small USB power source.

For those interested in trying this out, the necessary files and instructions are available on a GitHub page. There are numerous scenarios where this system could be useful, particularly in situations where energy requirements need to remain low, such as during a long car trip or when there is no electrical power. It’s also reasonable to assume that the Pi will not be capable of heavy transcoding or streaming 4K video due to its power and processing limitations, but such expectations would be unreasonable. For such tasks, a more robust system would be required.
