# 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.
|
|
|
|
**I will be very busy with other stuff until July, and won't be able to
|
|
dedicate much time to librespot. Please keep using it and open issues,
|
|
but it's likely I won't be able to answer them until then. Non-trivial
|
|
pull requests will probably not be reviewed either.**
|
|
|
|
## Building
|
|
Rust 1.15.0 or later is required to build librespot.
|
|
|
|
**If you are building librespot on macOS, the homebrew provided rust may fail due to the way in which homebrew installs rust. In this case, uninstall the homebrew version of rust and use [rustup](https://www.rustup.rs/), and librespot should then build.**
|
|
|
|
It also requires a C, with portaudio.
|
|
|
|
On debian / ubuntu, the following command will install these dependencies :
|
|
```shell
|
|
sudo apt-get install build-essential portaudio19-dev
|
|
```
|
|
|
|
On Fedora systems, the following command will install these dependencies :
|
|
```shell
|
|
sudo dnf install portaudio-devel make gcc
|
|
```
|
|
|
|
On macOS, using homebrew :
|
|
```shell
|
|
brew install portaudio
|
|
```
|
|
|
|
Once you've cloned this repository you can build *librespot* using `cargo`.
|
|
```shell
|
|
cargo build --release
|
|
```
|
|
|
|
## Usage
|
|
A sample program implementing a headless Spotify Connect receiver is provided.
|
|
Once you've built *librespot*, run it using :
|
|
```shell
|
|
target/release/librespot --username USERNAME --cache CACHEDIR --name DEVICENAME
|
|
```
|
|
|
|
## Discovery mode
|
|
*librespot* can be run in discovery mode, in which case no password is required at startup.
|
|
For that, simply omit the `--username` argument.
|
|
|
|
## 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.
|
|
|
|
```shell
|
|
cargo build --features portaudio-backend
|
|
target/release/librespot [...] --backend portaudio
|
|
```
|
|
|
|
The following backends are currently available :
|
|
- ALSA
|
|
- PortAudio
|
|
- PulseAudio
|
|
|
|
## Cross-compiling
|
|
A cross compilation environment is provided as a docker image.
|
|
Build the image from the root of the project with the following command :
|
|
|
|
```
|
|
$ docker build -t librespot-cross -f contrib/Dockerfile .
|
|
```
|
|
|
|
The resulting image can be used to build librespot for linux x86_64, armhf (compatible e. g. with Raspberry Pi 2 or 3, but not with Raspberry Pi 1 or Zero) and armel.
|
|
The compiled binaries will be located in /tmp/librespot-build
|
|
|
|
```
|
|
docker run -v /tmp/librespot-build:/build librespot-cross
|
|
```
|
|
|
|
If only one architecture is desired, cargo can be invoked directly with the appropriate options :
|
|
```shell
|
|
docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --no-default-features --features alsa-backend
|
|
docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --target arm-unknown-linux-gnueabihf --no-default-features --features alsa-backend
|
|
docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --target arm-unknown-linux-gnueabi --no-default-features --features alsa-backend
|
|
```
|
|
|
|
Don't forget to set the `with-tremor` feature flag if your target device does not have floating-point capabilities.
|
|
|
|
## Development
|
|
When developing *librespot*, it is preferable to use Rust nightly, and build it using the following :
|
|
```shell
|
|
cargo build --no-default-features --features "nightly 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.
|
|
Use at your own risk.
