This week I found out about MPRIS: Media Player Remote Interfacing Specification. It is a standardized D-Bus interface for exposing metadata and controlls from a music player. Thanks to MPRIS, other apps can integrate such a music player seamlessly, e.g. onto the computer lockscreen.
What else can you do with MPRIS? Stop or Snooze your alarm clock! That’s right, the alarm clock Birdie designed for Linux phones (PinePhone) now acts as a music player. Now you don’t have to unlock the phone to stop an alarm in the morning!
