• ffmpeg exited with code 1 : Input/output error

  30 mai 2024, par Alessandro1918

  On my backend Node server, I am trying to read a stream from an online radio station, and save the audio as a file in my computer. As streams don't have start/end, I'm choosing to record an arbitrary value of 5 seconds.

  


  For this problem, I'm using the fluent-ffmpeg npm package for ffmpeg wrapper. Also, the @ffmpeg-installer/ffmpeg npm package to point to the directory of my local ffmpeg binary. As stream input, I'm reading from 89 FM - A Rádio Rock, a radio from São Paulo, BR, with the stream available at http://26593.live.streamtheworld.com/RADIO_89FMAAC.aac

  


  Here is the code I put together :

  


  import ffmpeg from "fluent-ffmpeg"
import ffmpegInstaller from "@ffmpeg-installer/ffmpeg"
ffmpeg.setFfmpegPath(ffmpegInstaller.path);
console.log(ffmpegInstaller.path)
console.log(ffmpegInstaller.url)
console.log(ffmpegInstaller.version)

const pathInput = "http://26593.live.streamtheworld.com/RADIO_89FMAAC.aac"
// const pathInput = "./tmp/demo.avi"
const pathOutput = "./tmp/output.m4a"

ffmpeg()
  .input(pathInput)
  .duration(5)
  .save(pathOutput)
  .on("start", function(command) {
    console.log("Spawned Ffmpeg with command: " + command)
  })
  .on("error", function (err) {
    console.log("An error occurred: " + err.message)
  })
  .on("end", async function () {
    console.log("Processing finished!")
  })


  


  On my local machine (Mac, running darwin-x64), the program outputs OK :

  


  /.../node_modules/@ffmpeg-installer/darwin-x64/ffmpeg
https://evermeet.cx/ffmpeg/
92718-g092cb17983
Spawned Ffmpeg with command: ffmpeg -i http://26593.live.streamtheworld.com/RADIO_89FMAAC.aac -y -t 5 ./tmp/record.m4a
Processing finished!


  


  On my docker container (linux-x64), which I need to deploy the project, the ffmpeg returns an error :

  


  /usr/app/node_modules/@ffmpeg-installer/linux-x64/ffmpeg
https://www.johnvansickle.com/ffmpeg/
20181210-g0e8eb07980
Spawned Ffmpeg with command: ffmpeg -i http://26593.live.streamtheworld.com/RADIO_89FMAAC.aac -y -t 5 ./tmp/output.m4a
main-1  | An error occurred: ffmpeg exited with code 1: http://26593.live.streamtheworld.com/RADIO_89FMAAC.aac: Input/output error


  


  Dockerfile for the container :

  


  FROM node:alpine

WORKDIR /usr/app

COPY package*.json ./

# Install ffmpeg in the container:
RUN apk update
RUN apk add ffmpeg

RUN npm install

COPY . .

CMD [ "npm", "run", "dev" ]



  


  Obs : this error seems to happen only for stream -> file save. When using as input a path from a local .avi file (thus, converting from .avi to .m4a), both localhost and docker versions run OK.

  


  Has anyone has any clue as to why this error happens on this version ?
Or how I can run a ffmpeg command, server-side, on a docker container, to record a radio stream ?

  


• using ffmpeg -f ffmetadata to get metadata for a stream [on hold]

  23 avril 2014, par user645402

  I have a stream that I can get the metadata for using ffmpeg :

  ffmpeg -i <stream url="url"> -f ffmetadata -
  
  </stream>

  This works great for the first song, but then returns. The issue is that the stream is from a radio station which plays song after song - i.e. the metadata is changing as time goes on. However, this command will only give metadata for the song currently playing and then exit.

  I would like it to keep flowing the metadata as it updates in the stream.

• How do I write a simple script which calls ffmpeg and records an audio stream ?

  29 janvier 2016, par user2192778

  I would like to write a script which calls ffmpeg and begins recording an internet radio stream.

  This command is simple :
  ffmpeg -i http://myaudiostream.com output.mp3

  I understand how to make a .bat file, I just don’t know specifically how to code these instructions.

  Can I have some help ?
  I haven’t written a script before, though I understand how it works. I don’t know any of the syntax.
