• Extract audio from youtube in a client-side script

  5 mai 2018, par Kevin

  There are a lot of node libraries for turning a youtube video into an audio stream, but all of them rely on a C-library called ffmpeg.

  Ffmpeg has been ported to javascript as well, but it has a 30MB size, which seems rather cumbersome (ffmpeg does a lot more than just rip audio from youtube, it has many advanced audio filtering techniques that won’t be needed for this application).

  Lastly, I came across this link,https://hackernoon.com/how-to-build-an-audio-processor-in-your-browser-302cb7aa502a, which claims to be a client-side audio processor but really does all the stuff on the server-side, and then says that stuff can’t be done in the client because of CORS (not sure I understand this, can’t CORS be avoided with a simple flag in the request ?).

  Does anyone know of any way to stream audio within the client-side browser, specifically from youtube, in a manner that’s general and unopposed ?

• Error ffmpeg during upload stream to youtube

  4 mars 2018, par wolacinio

  I have problem with transmitting video and sound via rtsp to rtmp youtube.
  Run as :

  ffmpeg -rtsp_transport tcp -i "rtsp://user:pass@192.168.1.100:554/cam/realmonitor?channel=1&subtype=0" -vcodec copy -acodec aac -ar 44100 -b:a 128k -ac 1 -f flv rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx

  After few hours transmitting stops with error visible on the picture.
  

  How can I resolve this ?

• Simple Question About Subprocess popen + screen +ffmpeg + youtube-dl

  2 juin 2021, par El_Barto_404

  ffmpeg -i "$(youtube-dl -x -g "https://youtu.be/xhXq9BNndhw")" -f s16le -ac 2 -ar 48000 -acodec pcm_s16le input.raw


  


  can anyone put this inside a popen process after a screen -S Convert ?

  


  I tried already with ' ', with commas.. but nothing

  


  I built a bot on telegram which if you send :

  


  .mandala youtubelink


  


  it takes the link and converts the video from YouTube into a uncompressed file, I need it for a music bot which streams those uncompressed files.

  


  if I run in console :

  


  ffmpeg -i "$(youtube-dl -x -g "https://youtu.be/xhXq9BNndhw")" -f s16le -ac 2 -ar 48000 -acodec pcm_s16le input.raw 


  


  it works but when I try with screen and popen it doesn't.. why ?

  


  @helper.register(pattern=r'.mandala (.+)')
async def mu2342sicbfffffffot(e):
    cheater = e.pattern_match.group(1)
    cheat = cheater
    myorder2224 = ''' "$(youtube-dl -x -g "{}")" '''
    doit = (myorder2224.format(cheater))

    ###  I already try to format the variable 
    ###  and put doit after -i and 
    ###  everything was in '' and commas 
    ###  like 'ffmpeg', 'i*, doit, '-f'...
    ###  and so on but nothing.. but nope doesn't work.

    p = subprocess.call(['screen','-S','onveter',' ffmpeg -i "$(youtube-dl -x -g "https://www.youtube.com/watch?v=Sw5HQbYGoCA")" -f s16le -ac 1 -acodec pcm_s16le -ar 96k  input.pcm'],shell=True)
  await helper.control_panel.send_message(config.chat, "La sto a manna")
  time.sleep(14)
  


  


  I REPEAT ONE MORE TIME :
HOW CAN I USE THAT FFMPEG COMMAND INSIDE A POPEN SUBPROCESS AFTER A Screen -S Convert ?

  


  IF SOMEONE WANT TO KNOW WHY :
Because I want to convert youTube videos to file .raw / .pcm
