ytd-rs

An async, feature-rich Rust wrapper for yt-dlp.

Features

Async API: Built on top of tokio.
Builder Pattern: Fluent API for configuring downloads.
Structured Metadata: Extract video info as JSON via serde.
Custom Arguments: Passthrough for any yt-dlp flag.

Prerequisites

You must have yt-dlp installed and available in your PATH.

Usage

Simple Download

use ytd_rs::YtDlp;
use std::path::PathBuf;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let ytd = YtDlp::new("https://www.youtube.com/watch?v=uTO0KnDsVH0")
        .output_dir(PathBuf::from("./downloads"))
        .arg("--quiet");

    let result = ytd.download().await?;
    println!("Output: {}", result.output());
    Ok(())
}

Extract Audio

use ytd_rs::YtDlp;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    YtDlp::new("https://www.youtube.com/watch?v=uTO0KnDsVH0")
        .extract_audio_only("mp3")
        .download()
        .await?;
    Ok(())
}

Get Video Metadata

use ytd_rs::YtDlp;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let ytd = YtDlp::new("https://www.youtube.com/watch?v=uTO0KnDsVH0");
    let infos = ytd.get_info().await?;
    
    for info in infos {
        println!("Title: {}", info.title);
        println!("Duration: {:?}", info.duration);
    }
    Ok(())
}

Streaming Output (Progress Bars)

If you want to track the progress of a long-running download, you can stream the standard output line-by-line:

use ytd_rs::YtDlp;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut process = YtDlp::new("https://www.youtube.com/watch?v=uTO0KnDsVH0")
        .download_process()
        .await?;

    while let Some(line) = process.next_line().await? {
        // e.g. "[download]  10.0% of 50.00MiB at 1.00MiB/s ETA 00:50"
        println!("yt-dlp output: {}", line);
    }

    process.wait().await?;
    println!("Download finished successfully!");
    Ok(())
}
