[TOC]

## Context
> [name=Sanket] dinesh, bhanu, shalini - just tested mopidy. that underlying library behind that rpi cassette player which mike or somebody from apc suggested. well its not what i was looking for radio. i was thinking that it will stream music. but it just gives music player controls over http for playing music on raspberry pi. (apparently that is a definition for music player daemon, which i realised only now). it maybe useful for providing admin-like-control for devices like phone booth pi. but not for users/listeners.

## Features

### Optional

## Readings

### Mopidy docs References
1. [Mopidy Architecture](https://docs.mopidy.com/en/latest/api/architecture/): The overall architecture of Mopidy is organized around multiple frontends and backends. The frontends use the core API. The core actor makes multiple backends work as one. The backends connect to various music sources. The core actor use the mixer actor to control volume, while the backends use the audio actor to play audio.
2. [Running Mopidy as Service](https://docs.mopidy.com/en/latest/service/): The Mopidy service runs as the mopidy user, which is automatically created when you install the Mopidy package. The mopidy user will need read access to any local music you want Mopidy to play.
3. [Mopidy Using Gstreamer](https://docs.mopidy.com/en/latest/ext/stream/) We can connect to various frontends (across different protocols http, MPD, MPRIS, UpnP) via their extensions. here is the streaming extension(comes bundled) which uses Gstreamer
* Requirements: You should Install and Run a Gstreamer Server and configure in your mopidy app.
4. The core api gives access to the controllers of Tracklist, Playback, Playlist, Mixer, Library modules. here is the core api provider [docs](https://docs.mopidy.com/en/latest/api/backend/)
