• Is there a pre built compiled version of ffmpeg for iphone ?

  29 août 2012, par Meir

  I am struggling in compiling ffmpeg with no success. Is there any ready for use, pre compiled libraries for the iphone ?

  In general, what I need is to stream a radio station in mms wmv format, is there any other solution ?

  Thanks

• Concat audio files then call create file

  11 mai 2020, par bleepbloopbleep

  I am new and am trying to concat a folder of audio files and then stream the create file with ffmpeg in node.js.

  



  I thought I could call the function that creates the file with await and then when it's done the code would continue allowing me to call the created file. However thats not whats happening. I am getting a "file undefined"

  



  Main function

  



  //CONCATS THE FILES
  await concatAudio(supportedFileTypes.supportedAudioTypes, `${path}${config[typeKey].audio_directory}`);

  // CALLS THE FILE CREATED FROM concatAudio
  const randomSong = await getRandomFileWithExtensionFromPath(
    supportedFileTypes.supportedAudioTypes,
    `${path}${config[typeKey].audio_final}`
  );


  



  concatAudio function

  



  var audioconcat = require('audioconcat');
const getRandomFileWithExtensionFromPath = require('./randomFile');
const find = require('find');

// Async Function to get a random file from a path
module.exports = async (extensions, path) => {
  // Find al of our files with the extensions
  let allFiles = [];

  extensions.forEach(extension => {
    allFiles = [...allFiles, ...find.fileSync(extension, path)];
  });

  await audioconcat(allFiles)
    .concat('./live-stream-radio/final/all.mp3')
    .on('start', function(command) {
      console.log('ffmpeg process started:', command);
    })
    .on('error', function(err, stdout, stderr) {
      console.error('Error:', err);
      console.error('ffmpeg stderr:', stderr);
    })
    .on('end', function(output) {
      console.error('Audio created in:', output);
    });

  // Return a random file

  // return '/Users/Semmes/Downloads/live-stream-radio-ffmpeg-builds/live-stream-radio/final/all.mp3';
};


  


• How convert High bitrate mp3 to lower rate using ffmpeg in android

  23 mars 2018, par Android Team

  We want to convert 320kbps mp3 file to 128kbps mp3 so currently we are using below ffmpeg command but its not working.

  ffmpeg -i input.mp3 -codec:a libmp3lame -qscale:a 5 output.mp3

  Result :-the output bitrate same as input mp3.

  And we are following the FFmpeg Encoding guideline for that here is the link :- https://trac.ffmpeg.org/wiki/Encode/MP3

  so please suggest any solution.
