• YouTube_dl doesn't find ffmpeg

  10 octobre 2019, par user702846

  I would like to download a set of youtube file as audio, mp3.

  import youtube_dl
  
  
  
  ydl_opts = {
  
      'format': 'bestaudio/best',
  
      'postprocessors': [{
  
          'key': 'FFmpegExtractAudio',
  
          'preferredcodec': 'mp3',
  
          'preferredquality': '192',
  
      }],
  
  }
  
  with youtube_dl.YoutubeDL(ydl_opts) as ydl:
  
      ydl.download(['https://www.youtube.com/watch?v=cmNEDz7YZSw']) 

  It successfully download the file as m4a - however complains about ffmpeg installation.

  ERROR: ffprobe/avprobe and ffmpeg/avconv not found. Please install one.

  I do have ffmpeg installed and located at /usr/local/bin/ffmpeg and also have added to my PATH using

  os.environ["PATH"] += '/usr/local/bin/ffmpeg'

  but still the error is there. I am using MacOS Mojave and my ffmpeg specification are as following,

  fmpeg version 4.1.3 Copyright (c) 2000-2019 the FFmpeg developers
  
    built with Apple LLVM version 10.0.1 (clang-1001.0.46.4)
  
    configuration: --disable-encoder=vorbis --enable-libvorbis --enable-libmp3lame --disable-x86asm

• Streaming ffmpeg output directly to dispatcher

  4 novembre 2020, par PP_Hyperion

  I'm trying to play music with my discord bot and I want to use ffmpeg to specify the start of the music, which works perfectly fine, but I can only download the music with ffmpeg and then play it. I want ffmpeg to process it and then also stream it to play the music.

  



  Here is the code I use to download and then play the music :

  



  message.member.voiceChannel.join().then((con, err) => {
    ytPlay.search_video(op, (id) => {
        let stream = ytdl("https://www.youtube.com/watch?v=" + id, {
            filter: "audioonly"
        });
        let audio = fs.createWriteStream('opStream.divx');

        proc = new ffmpeg({
            source: stream
        })
        proc.withAudioCodec('libmp3lame')
            .toFormat('mp3')
            .seekInput(35)
            .output(audio)
            .run();
        proc.on('end', function() {
            let input = fs.createReadStream('opStream.divx');
            console.log('finished');
            guild.queue.push(id);
            guild.isPlaying = true;
            guild.dispatcher = con.playStream(input);
        });
    });
})


  



  Is it possible to do what I want and if yes how ?
