librespot

librespot is an open source client library for Spotify. It enables applications to use Spotify's service, without using the official but closed-source libspotify. Additionally, it will provide extra features which are not available in the official library.

Status

librespot is currently under development and is not fully functional yet. You are however welcome to experiment with it.

Building

Rust 1.7.0 or later is required to build librespot.

It also requires a C and C++ toolchain, with libprotoc and portaudio.

On debian / ubuntu, the following command will install these dependencies :

sudo apt-get install build-essential portaudio19-dev libprotoc-dev

On Fedora systems, the following command will install these dependencies :

sudo dnf install portaudio-devel libprotoc-dev make gcc gcc-c++

On OS X, using homebrew :

brew install portaudio protobuf

Once you've cloned this repository you can build librespot using cargo.

cargo build --release

Usage

A sample program implementing a headless Spotify Connect receiver is provided. Once you've built librespot, run it using :

target/release/librespot --appkey APPKEY --username USERNAME --cache CACHEDIR --name DEVICENAME

Discovery mode

librespot can be run in discovery mode, in which case no password is required at startup. dns-sd or avahi's compatibility layer is required for this. On debian/ubuntu this is the libavahi-compat-libdnssd-dev package. On Fedora, this is the avahi-compat-libdns_sd-devel package. It come preinstalled on OS X.

It must be enabled at build time :

cargo build --release --features discovery

When running librespot simply omit the --username argument.

Facebook Accounts

librespot can be built with Facebook authentication support. OpenSSL is required for this.

cargo build --release --features facebook
target/release/librespot --appkey APPKEY --cache CACHEDIR --name DEVICENAME --facebook

This will print a link to the console, which must be visited on the same computer librespot is running on.

Audio Backends

librespot supports various audio backends. Multiple backends can be enabled at compile time by enabling the corresponding cargo feature. By default, only PortAudio is enabled.

A specific backend can selected at runtime using the --backend switch.

cargo build --features portaudio-backend
target/release/librespot [...] --backend portaudio

The following backends are currently available :

• PortAudio
• PulseAudio (feature pulseaudio-backend, --backend pulseaudio)

Development

When developing librespot, it is preferable to use Rust nightly, and build it using the following :

cargo build --no-default-features --features portaudio-backend

This produces better compilation error messages than with the default configuration.

Disclaimer

Using this code to connect to Spotify's API is probably forbidden by them, and might result in you application key getting banned. Use at you own risk
