• Looking for a non-FFMPEG/non-Lame Python audio converter for Android [closed]

  1er avril, par Marcelcolt

  So as the title suggests, I'm looking for another way to convert audio.
I am currently using PyTubeFix to download audio from YouTube. That works awesome, but it downloads in M4A.
I would really like it in MP3.

  


  Most converter libraries and packages use FFMPEG. I've tried to download it through Termux and PyDroid3, but that doesn't work. I've tried to compile it for Android with NDK, but I am so lost in what I am supposed to be doing...
Same goes for Lame.
I've been at it for over a week now, but I can't find any other way to convert.

  


  AI only suggests that I write a library of my own, but not HOW to do that (only that I'd have to convert M4A to WAV first and then back to MP3).

  


  So I would love it if someone could point me towards a library or package that doesn't depend on FFMPEG or Lame.

  


  I hope you guys can help !

  


• Run ffmpeg audio under Windows with Flutter

  11 janvier, par Chris

  I'd like to stream audio comming from my microphone in my flutter app in the windows desktop version.

  


  Since there is no library that seems to do such thing while supporting windows desktop app, I have tried using Process like this :

  


  // Start the FFmpeg process to capture audio
ffmpegProcess = await Process.start(
  'ffmpeg',
  [
    '-f', 'dshow', // Specify DirectShow input for Windows
    '-i', 'audio="$selectedMic"', // Input audio device (selected mic)
    '-f', 'wav', // Set audio format
    '-ar', '44100', // Set audio sample rate
    '-ac', '1', // Mono channel
    '-b:a', '128k', // Set audio bitrate
    'pipe:1', // Output to stdout
  ],
);

// Listen for data on stdout (audio stream)
ffmpegProcess.stdout.listen((data) async {
  // Send audio data to the server as it comes in
  await sendAudioToServer(data);
});


  


  I've tested the command directly in my terminal (not in the flutter app) and it works fine.

  


  When I run this code in my Flutter app, my task manager also shows a "ffmpeg" process, but somehow there is no stream output in flutter, even after ensuring that the selectedMic variable is correct or even when its hardcoded.

  


  Since this command runs without issue in my terminal and even in python, I am wondering why it does not work in Flutter.

  


  Starting my vscode as administrator also don't solve the issue (I wanted to check if it's a permission issue).

  


  Also relevant : When I run the "ffmpeg -version" command, I get an output for the version, meaning that this is not an installation problem (ffmpeg bin folder is in my PATH environment variable). The problem seems to come from recording from the microphone in flutter, but I don't get why.

  


  ffmpegProcess = await Process.start('ffmpeg', ['-version']);  // this works


  


  I'd love to get some suggestions where the problem could come from or any kind of alternative solutions.

  libavcodec/sanm : clear codec47 diff buffers with specific color
  The codec47 header provides colors to use to clear the
  
  2 difference buffers. This fixes artifacts (black hair, faces) in
  
  Curse of Monkey Island "CURSERNG.SAN" video.
