• 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

  


• Anomalie #1934 : Liberons les dl, dd, dt !

  Hop, je ne crois pas avoir déjà utilisé ce raccourci, mais puisqu’il est déjà dans la nature et que d’autres personnes l’utilise déjà je pense qu’il est bon de le garder pour ne pas péter la compat ascendante lors de la sortie de la 3.1.

• Strange error with ffmpeg and unoconv in python script

  27 mai 2015, par Avery Ripoll Crocker

  I am creating a python script that can be used by other people to convert files. However when I use this script I keep getting a weird error when I run the subprocess for unoconv, this error is :

  Traceback (most recent call last):
  
    File "conversion.py", line 15, in <module>
  
      check_call(["unoconv", "-f", Fileextension, filename])
  
    File "/usr/lib/python2.7/subprocess.py", line 540, in check_call
  
      raise CalledProcessError(retcode, cmd)
  
  subprocess.CalledProcessError: Command '['unoconv', '-f', '.pdf', 'journal.doc']' returned non-zero exit status 1
  
  </module>

  I have looked through various resources for this, but the one answer I have been receiving is that I must have set up the unoconv line incorrectly. I have checked several times that the code is correct, and it is. The other peculiar thing is that my code for ffmpeg works. Does anybody have an idea as to why this happens.

  Here is my program :

  print "If at any point you wish to quit the program hit Ctrl + C"
  
  
  
  filetype = raw_input("What kind of file would you like to convert? Audio, Image, Video or Document: ")
  
  
  
  if filetype == "Document":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .txt: ")
  
     from subprocess import check_call
  
     check_call(["unoconv", "-f", Fileextension, filename])
  
  
  
  elif filetype == "Audio":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .mp3: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])
  
  
  
  elif filetype == "Video":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .mp4: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])
  
  
  
  elif filetype == "Image":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .Jpeg: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call    
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])
