[cbindgen](https://github.com/eqrion/cbindgen)-based API for C/C++ users.

---

> **NOTE**: [rav1e](https://github.com/xiph/rav1e) integrates with [cargo-c](https://github.com/lu-zero/cargo-c) to directly provide the C-API. From the release 0.1.0 you should use *cargo-c* and rav1e directly.

---

## Status

The C-API is now part of [rav1e](https://github.com/xiph/rav1e/#building-the-c-api). **DO NOT USE THIS REPOSITORY**

## Usage
You may generate the library and the header file using a simple `Makefile` or calling `cargo build`.

The Makefile supports installing the library, the header and the `pkg-config` file.

### Makefile
A quite simple makefile is provided:

``` sh
# Build librav1e.a, rav1e.h and rav1e.pc
$ make
```

``` sh
# Install librav1e.a, rav1e.h and rav1e.pc
$ make DESTDIR=${D} prefix=${prefix} libdir=${libdir} install
```

``` sh
# Remove librav1e.a, rav1e.h and rav1e.pc
$ make DESTDIR=${D} prefix=${prefix} libdir=${libdir} uninstall
```

### cargo
Currently `cargo install` does not work for libraries.

```
$ cargo build
```
or
```
$ cargo build --release
```

The header will be available as `include/rav1e.h`, the library will be in `target/<debug or release>/librav1e.<so or dylib>`
Look in `c-examples` for working examples.

## Windows binaries
Automated Windows binaries (x86-64 and ARM64) are generated by [AppVeyor](https://ci.appveyor.com/project/lu-zero/crav1e) (available for download under the Artifacts tab).

## Developing
I suggest to use the cargo [paths override](https://doc.rust-lang.org/cargo/reference/config.html) to have a local `rav1e`:

```
# Clone the trees
$ git clone https://github.com/xiph/rav1e
$ git clone https://github.com/lu_zero/crav1e
# Setup the override
$ cd crav1e
$ mkdir .cargo
$ echo 'paths=["../rav1e"]' > .cargo/config
# Check it is doing the right thing
$ cargo build
```
