# Rust wrapper for AOMedia AV1 decoder
It's a minimal safe wrapper that allows decoding individual AV1 frames. It's meant for decoding AVIF images.
## Usage
See [`examples/topng.rs`](examples/topng.rs) for the full code.
You'll need the [avif-parse](https://lib.rs/avif-parse) crate to get AV1 data out of an AVIF file, and the [yuv](https://lib.rs/yuv) crate to convert YUV pixels into RGB.
```rust
let avif = avif_parse::read_avif(file)?;
let mut d = Decoder::new(&Config {
threads: num_cpus::get(),
})?;
let img = d.decode_frame(&avif.primary_item)?;
match img.rows_iter()? {
RowsIters::YuvPlanes8 {y,u,v,chroma_sampling} => {
match chroma_sampling {
color::ChromaSampling::Cs444 => {
yuv_444(y, u, v).map(|px| {
// here's your YUV pixel
});
},
}
},
}
```
