Module @drop-radio/ffmpeg

This library exposes portions of the ffmpeg and ffprobe commandline tool interfaces to be used in operations on the backend.

Would you like to use it?

This module is intended only for internal use within the drop-radio server codebase. If you are working on a module with the scope:server tag, you may import the library and its functions:

import { ffprobeFormat, hlsStream } from '@drop-radio/ffmpeg'

const inputFile = 'path/to/media/file.wav'
const workingDir = 'stream/output/directory'

const {
  format: { filename, duration },
} = ffprobeFormat(inputFile)

const duration_us = Number.parseInt(duration.replace('.', ''))

const sub = hlsStream(inputFile, workingDir).subscribe({
  next({ out_time_us }) {
    const percent = ((100 * out_time_us) / duration_us).toFixed(2)
    console.log(`streaming ${filename} ... ${percent}% complete`)
  },
  error(err) {
    console.error(err)
    sub.unsubscribe()
  },
  complete() {
    console.log('done'!)
  },
})
