Audio Streaming Server with Axum

[Tahinli]

Summary

Hi, I must develop audio streaming service. I use Dioxus for frontend and Axum as a backend. I can play streams with html audio in Dioxus but I don't know how to create my own audio stream with URL. I'm lack of knowledge to find out what to do and how to do. I just know that I have to do and I should be able to do with these awesome Dioxus and Axum.

How can I create audio stream with URL that html audio component can consume and play without problem.

axum version

0.7.4

I did this

async fn stream() -> impl IntoResponse {
    println!("Stream");
    let header = [
        (header::CONTENT_TYPE, "audio/mpeg"),
        (header::CONTENT_LENGTH, ""),
        (header::TRANSFER_ENCODING, "chunked"),
        (header::CACHE_CONTROL, "no-cache, must-revalidate"),
        (header::PRAGMA, "no-cache"),

    ];
    let file = File::open("audios/audio.mp3").await.unwrap();
    let stream = ReaderStream::new(file);
    (header,Body::from_stream(stream))
}

and connected to router.
Problem is people can see total length and play the time that they want.

But i want it to make media time equal for every client and prevent them to reach future or previous data like this. I don't want to make client fetch all data from server at once. They should not see total length also.

How can I do like this ?

You can use ServeFile. See: #608 (comment) Edit: not relevant to the question

Take a look at this PR: https://github.com/tokio-rs/axum/pull/3047/files#diff-85ae2acd48337869f0504aa4eced18f7129187436fedaeee5e5c941c41d6292d. Specifically at the try_stream function.
Also, take a look at how ServeDir implements sending a portion of a file https://docs.rs/tower-http/latest/src/tower_http/services/fs/serve_dir/future.rs.html#253. It seems like you want to manually send what part of the file you want. I recommend using an AtomicUsize to keep track of which part of the file you should send to everyone.

Hi, Does this one solve client sync for everybody ? I was trying to sync stream equal for everyone. I don't want to let people seek further or past about media but allow them to follow same moment of stream.

I updated my answer. I didn't correctly read you question originally, sorry.

Thanks a lot.
