README

libopus_sys

libopus_sys is an FFI-Rust-binding to Opus version 1.5.

Orginally, this sys-crate was made to empower the serenity-crate to build audio features on Windows, Linux, and Mac. However, it's not limited to that.

Everyone is welcome to contribute, check out the CONTRIBUTING.md for further guidance.

Building

Requirements

If you want to build Opus, you will need cmake.

If you have pkg-config, it will attempt to use that before building.

You can also link a pre-installed Opus, see Pre-installed Opus below.

This crate provides a pre-built binding. In case you want to generate the binding yourself, you will need Clang, see Pre-installed Opus below for further instructions.

Linking

libopus_sys links to Opus 1.5 and supports Windows, Linux, and MacOS By default, we statically link to Windows, MacOS, and if you use the musl-environment. We will link dynamically for Linux except when using mentioned musl.

This can be altered by compiling with the static or dynamic feature having effects respective to their names. If both features are enabled, we will pick your system's default.

Environment variables named LIBOPUS_STATIC or OPUS_STATIC will take precedence over features thus overriding the behaviour. The value of these environment variables have no influence of the result: If one of them is set, statically linking will be picked.

Pkg-Config

By default, libopus_sys will use pkg-config on Unix or GNU. Setting the environment variable LIBOPUS_NO_PKG or OPUS_NO_PKG will bypass probing for Opus via pkg-config.

Pre-installed Opus

If you have Opus pre-installed, you can set LIBOPUS_LIB_DIR or OPUS_LIB_DIR to the directory containing Opus.

Be aware that using an Opus other than version 1.5 may not work.

Generating The Binding

If you want to generate the binding yourself, you can use the generate_binding-feature.

Be aware, bindgen requires Clang and its LIBCLANG_PATH environment variable to be specified.
