Throws UnrecognizedFormat while playing audio generated by ffmpeg and youtubedl.

[Sreyas-Sreelal]

The decoder seems not working with audio files generated by youtubedl and ffmpeg. Here's a minimal repro

1. Run

youtube-dl ytsearch1:okay --extract-audio --audio-format mp3 --output music.mp3

2. Build and run

use rodio::Sink;
use std::io::BufReader;

fn main() {
    let device = rodio::default_output_device().unwrap();
    let sink = Sink::new(&device);
    let file = std::fs::File::open("music.mp3").unwrap();
    sink.append(rodio::Decoder::new(BufReader::new(file)).unwrap());
    sink.sleep_until_end();
}

Output

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: UnrecognizedFormat', src/libcore/result.rs:999:5
note: Run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

This is the same case for .wav files too. The audio files works perfectly with other players.

I'm currently having UnrecognizedFormat errors too. Few second long mp3 sound effects. What's weird is that they're from a series of similar sound effects (like punch1.mp3 ~ punch7.mp3), but only 2 of them give errors.

Downloaded the soundpack from http://df.zweistein.cz/soundsense/ . '\soundpack\packs\battle\hit\punch\punch4.mp3' and '\soundpack\packs\battle\hit\push\push5.mp3' .

I'm currently having the same issue, did you manage to solve it by any chance?

Same issue here but not mp3s, just regular wav files..

This might have larger scope than just ffmpeg and youtubedl?

Is there some kind of bitrate limit? These samples are 48kHz 24bit

    sink.append(rodio::Decoder::new(BufReader::new(file)).unwrap());
    sink.sleep_until_end();
}
