• How to yt-dlp extract youtube audio-only to 32-bit float 48000 .wav ? [closed]

  28 avril 2024, par Rowe Morehouse

  My use case : Extract just the audio from a youtube URL directly to a .wav at 32-bit float 48000.

  


  Preferably without any post process args or secondary passes or after-the-fact conversion or muxing.

  


  I want f32le, aka PCM_f32le, aka PCM 32-bit floating-point little-endian, which is supported by ffmpeg. Also want 48000 sample rate, as stated.

  


  Is this possible ?

  


  My current command :

  


  yt-dlp -f bestaudio --extract-audio --audio-format wav --audio-quality 0


  


  What do I need to add to achieve my use case / job-to-be-done ??

  


• How to limit youtube-dl on video length when downloading a youtube stream

  26 novembre 2018, par M B

  Im trying to write a small script that records a live stream from youtube.
  when using youtube-dl.download function it just keeps on downloading until the stream ends, but i want to stop downloading after 20min or so.
  the problem is when i try killing it after a while the output is corrupted (im using mp4 format), and i tried fixing it with ffmpeg but a "moov atom not found" error occurs.

  How can i make youtube-dl (or any other tool) record a fixed length of a live stream ?

  Here’s a portion of the code :

  class recordingThread (threading.Thread):
  
  def __init__(self, threadID, output_location, name, yt_stream, start_time):
  
      threading.Thread.__init__(self)
  
  
  
      self.threadID = threadID
  
      self.output = os.path.abspath(output_location)
  
      self.name = name
  
      self.start_time = start_time
  
  
  
      self.ydl_opts = {'quiet': True,
  
                       'format': 'mp4',
  
                       'outtmpl': name+ '%(ext)s',
  
                       'sleep_interval': 2
  
                       }
  
      self.yt_stream = yt_stream.strip('\'"')
  
  
  
  def run(self):
  
      print "Starting %s Thread Recorder - %s" % (self.name, self.start_time)
  
  
  
      with youtube_dl.YoutubeDL(self.ydl_opts) as ydl:
  
          self.download_prc = ydl.download([self.yt_stream])

  Thanks.

• C# (discord music bot) Youtube to mp3 api with ffmpeg

  4 octobre 2017, par Greg Varadi

  Ok, so i have made a discord music bot before with youtube-dl in C#. But I don’t like it because it’s very slow. It has to download the song and then stream it using ffmpeg to discord. I don’t know but I think there is a quicker way.

  So, i decided to use a youtube to mp3 api to get a mp3 as quick as possible, but it won’t work. I mean I found an api that worked, but it’s the worst api I ever seen. This is the api : http://www.convertmp3.io/api/ . Sometimes doesn’t give the mp3, just a link to a download page that doesn’t work.

  I’m still searching for an api. Last time I found this :
  http://www.yt-mp3.com/fetch?v=VIDEO-ID&apikey=1234567
  This is for me the best. But ffmpeg doesn’t recognize the mp3. And I don’t know why because I can’t see any difference beetween them. Of course it’s probably something different but I can’t see what. And I don’t even know that ffmpeg will recognize any of these api’s mp3 files, but it’s working with this convertmp3.io api.

  So, my question is, is there someone who did something like this or someone who can give me advice ?

  By the way, I want something that is as quick as oxyl- or hime bot. And I know that using apis for getting mp3 from youtube videos is not by all means the most legal thing, because the copyright and stuff, but yeah... This is the only way, I think.
