Error: Output stream closed when trying to stream to express server using ffmpeg

Question

I'm getting to stream ytdl audio to my express server using ffmpeg but I'm always getting "Output stream closed"

there's my code

const express = require('express')
const ffmpeg = require('fluent-ffmpeg')
const ytdl = require('ytdl-core')

const app = express()

app.set('/:id', async (req, res) => {
    res.set('Content-Type', 'audio/mp3')

    ffmpeg(await ytdl(req.params.id, { format: 'audioonly', quality: 'highestaudio' }))
        .toFormat('mp3')
        .pipe(res, { end: true })
})

Not sure.. but as per docs, ytdl returns a stream while ffmpeg expects a file... You could try to write to file from ytdl and later stream from the same file location — Karan Gaur, Jun 08 '21 at 16:37
@KaranGaur ffmpeg expects a string or a stream.Readable which ytdl is a stream.Readable — Shahar Brandman, Jun 09 '21 at 11:44

In my case, I had the timeout problem:

    Error: Output stream closed
    at Timeout._onTimeout (C:\MYPATH\node_modules\fluent-ffmpeg\lib\processor.js:491:25)

I accessed the fluent-ffmpeg processor.js file and the following function appeared:

    setTimeout(function() {
      emitEnd(new Error('Output stream closed'));
      ffmpegProc.kill();
    }, 20);

I commented out the whole function. I don't know if it's the best solution, but it worked great for me.

Setting Content-Disposition header might help you:

res.set('Content-Disposition', `attachment; filename=${fileName}`),

Reference: https://github.com/fluent-ffmpeg/node-fluent-ffmpeg/issues/470#issuecomment-160200925

But this is not a great solution
