Multiple async download through one builder

[aaalloc]

Hi !

I wanted to know if it is possible to download multiple link from one builder asynchronously. I read the documentation and the code and I didn't found any clue for doing that...

Thanks in advance !

Hello, no, this is not supported by the API at the moment. Would the advantage be that you just need one yt-dlp/youtube-dl process to download multiple files? Because if that's not a problem, you could just use multiple builders and run them in parallel with something like future::join_all

Yeah thats what I basically did, here's a snippet:

async fn download_audio(link: &str) -> Result<YoutubeDlOutput, Error> {
    YoutubeDl::new(link)
        .socket_timeout("15")
        .extract_audio(true)
        .extra_arg("-x")
        .extra_arg("--continue")
        .extra_arg(r#"-o %(title)s.%(ext)s"#)
        .extra_arg("--prefer-ffmpeg")
        .extra_arg("--ppa")
        .extra_arg("ThumbnailsConvertor+FFmpeg_o:-c:v mjpeg -vf crop=\"'if(gt(ih,iw),iw,ih)':'if(gt(iw,ih),ih,iw)'\"")
        .extra_arg("--embed-metadata")
        .extra_arg("--embed-thumbnail")
        .extra_arg("--audio-format")
        .extra_arg("mp3")
        .extra_arg("-P")
        .extra_arg("...")
        .extra_arg("--no-simulate")
        .extra_arg("--no-progress")
        .run_async().await
}

pub async fn download_audio_from_links(
    url: String,
    state: tauri::State<'_, AsyncProcInputTx>,
) -> Result<(), String> {
    let links = retrieve_possible_links(&url);
    let mut futures = futures::stream::FuturesUnordered::new();
    for link in &links {
        futures.push(async move { download_audio(link).await });
    }
    while let Some(res) = futures.next().await {
        match res {
...................
        }
    }
    Ok(())
}

thank you !
