Implement MPRIS D-Bus interface in your application.
This library provides the essential functionalities for implementing the MPRIS D-Bus interface on the service side. This enables your application to become discoverable and controllable by other MPRIS-compatible media controllers, including but not limited to GNOME Shell, KDE Plasma, and other libraries such as mpris
.
This library supports all the following interfaces as defined in the specification:
- org.mpris.MediaPlayer2
- org.mpris.MediaPlayer2.Player
- org.mpris.MediaPlayer2.TrackList
- org.mpris.MediaPlayer2.Playlists
To implement these interfaces, this crate offers two flavors: you can either create your own struct and implement RootInterface
and PlayerInterface
(or with optional TrackListInterface
and PlaylistsInterface
), or you can use the ready-to-use Player
struct.
Feature | Description | Default |
---|---|---|
unstable |
Enables internal APIs and unstable features. | No |
For more detailed examples, see also the examples directory.
There is also a real-world example of this library being used in Mousai, a music recognizer application for Linux.
If you want to have more control, it is recommended to manually create your own implementation of the interfaces. You can do this by creating your own struct and implementing the required interfaces, then passing your struct as implementation in Server
. You can also use LocalServer
and the local version of the interfaces if your struct can't be sent and shared across threads.
use std::future;
use mpris_server::{
zbus::{fdo, Result},
Metadata, PlayerInterface, Property, RootInterface, Server, Signal, Time, Volume,
};
pub struct MyPlayer;
impl RootInterface for MyPlayer {
async fn identity(&self) -> fdo::Result<String> {
Ok("MyPlayer".into())
}
// Other methods...
}
impl PlayerInterface for MyPlayer {
async fn set_volume(&self, volume: Volume) -> Result<()> {
self.volume.set(volume);
Ok(())
}
async fn metadata(&self) -> fdo::Result<Metadata> {
let metadata = Metadata::builder()
.title("My Song")
.artist(["My Artist"])
.album("My Album")
.length(Time::from_micros(123))
.build();
Ok(metadata)
}
// Other methods...
}
#[async_std::main]
async fn main() -> Result<()> {
let server = Server::new("com.my.Application", MyPlayer).await?;
// Emit `PropertiesChanged` signal for `CanSeek` and `Metadata` properties
server
.properties_changed([
Property::CanSeek(false),
Property::Metadata(Metadata::new()),
])
.await?;
// Emit `Seeked` signal
server
.emit(Signal::Seeked {
position: Time::from_micros(124),
})
.await?;
// Prevent the program from exiting.
future::pending::<()>().await;
Ok(())
}
If you want to create a simple player without having to implement the interfaces, you can use the ready-to-use Player
struct that implements those interfaces internally. This struct has its own internal state, automatically emits properties changed signals, and allows you to connect to method and property setter calls.
However, Player
currently only supports the more commonly used org.mpris.MediaPlayer2
and org.mpris.MediaPlayer2.Player
interfaces.
use std::future;
use mpris_server::{zbus::Result, Player, Time};
#[async_std::main]
async fn main() -> Result<()> {
let player = Player::builder("com.my.Application")
.can_play(true)
.can_pause(true)
.build()
.await?;
// Handle `PlayPause` method call
player.connect_play_pause(|_player| {
println!("PlayPause");
});
// Run event handler task
async_std::task::spawn_local(player.run());
// Update `CanPlay` property and emit `PropertiesChanged` signal for it
player.set_can_play(false).await?;
// Emit `Seeked` signal
player.seeked(Time::from_millis(1000)).await?;
// Prevent the program from exiting.
future::pending::<()>().await;
Ok(())
