Sprints
Whiteboard
The music-hub will be a session-level service that is offered to app-authors for music playback. It will be integrated with the overall stack as follows:
---
| Music Hub |
---
--
| Platform API |
---
---
| QtMultimedia |
---
The primary interface to the functionality is via QtMultimedia's QML bindings and it is transparent to users of that API. Please note that traditional audio output is not covered by the music hub, i.e., it is specifically targeted to music playback as opposed to audio output.
Implementation choices:
* Frontend API: QtMultimedia QML bindings
* Backend API: C++
* Communication Protocol: MPRIS via DBUS
* Service-side playback backend: gstreamer 1.0
