MagicPlay: the Open Source AirPlay 177

Posted by Soulskill from the does-not-involve-shivan-dragons dept.
New submitter JonLech writes "Ever since Apple launched AirTunes in 2004 (later renamed AirPlay) they have remained unchallenged in the Wi-Fi music streaming market. With various manufacturers releasing AirPlay-only Wi-Fi speakers, Android and other non-Apple device users have been left out in the cold. Today that changes with the release of MagicPlay, an open standard for music streaming (think 'HTTP for music') with a BSD-licensed open source reference implementation that any app developer or hardware manufacturer can integrate into their products. For the Linux fans out there, I've written up some instructions on how to turn your Raspberry Pi into a MagicPlay device."

      You are implying that you would like hardware manufacturers to make a de-facto standard by selling devices first, and then open it up.

      This is the route AirPlay went so far, and where all vendor lock-in happens.

      A standard allows multiple parties to come together (hardware vendors, software devs, sellers) and have a common ground / interface, so everyone knows what they are talking about. So progress on spreading a open solution should be accelerated by defining a standard first.
