audiopus is a high-level binding of Opus version 1.3.
The crate uses audiopus_sys underneath.
Orginally, this crate was made to empower the serenity-crate to build audio features on Windows, Linux, and Mac.
Everyone is welcome to contribute,
check out the CONTRIBUTING.md for further guidance.
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.
The crate underneath, audiopus_sys, links to Opus 1.3 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.
By default, audiopus_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.
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 1.3 may not work.
Add this to your Cargo.toml:
