avio

Safe, high-level audio/video/image processing for Rust — backend-agnostic multimedia toolkit.

⚠️ Coming Soon — This crate is a placeholder and not yet fully implemented. The core crates (ff-probe, ff-decode, ff-encode) are under active development.

Overview

avio is the facade crate for the ff-* crate family. It re-exports the public APIs of all member crates behind feature flags, so you can depend on a single crate and opt into only the functionality you need.

Currently backed by FFmpeg, with planned support for GStreamer and other backends.

Feature Flags

Feature	Crate	Default
`probe`	`ff-probe`	yes
`decode`	`ff-decode`	yes
`encode`	`ff-encode`	yes
`filter`	`ff-filter`	no
`pipeline`	`ff-pipeline`	no
`stream`	`ff-stream`	no

Planned Usage

[dependencies]

# Default features: probe + decode + encode

avio = "0.5"



# With filter graph and pipeline support

avio = { version = "0.5", features = ["filter", "pipeline"] }



# Full feature set

avio = { version = "0.5", features = ["filter", "pipeline", "stream"] }

use avio::prelude::*;

let info = avio::probe::open("input.mp4")?;
println!("duration: {:?}", info.duration());

Minimum Supported Rust Version

Rust 1.93.0 or later (edition 2024).
