• disable muxing in YOUTUBE-DL

  3 février 2020, par user3515562

  I want to disbale post process in youtube-dl(2020.01.24).
  My batch file contains

  set /p ytlink=Enter the link of Youtube Video:-    
  
  youtube-dl -x -o D:\%%(title)s.%%(ext)s %ytlink%  
  
  pause  

  The youtube-dl first downloads webm file or any other file than use post process ffmpeg.exe to convert it.
  I want to disable post process.Their must be no post process happening after youtube-dl download.
  
   x is the option to only download audio file of the YouTube video in webm format .There is no post processing involved.But youtube-dl by default tries to convert the webm file to some other format, which is post processing.Post processing of audio file by default is one that i want to disable
  OS=Windows 10

  Using the laravel-ffmpeg librabry to convert video file from .webm to mp4 aws s3 bucket url and using following code.

  $videoFile = '/courses/images/1579626678msr-2020-01-21T17-11-18-771Z.webm';  //= upload/video1.mp4
  
     FFMpeg::fromDisk('s3')
  
      ->open($videoFile)
  
      ->getFrameFromSeconds(10)
  
      ->export()
  
      ->toDisk('s3')
  
      ->inFormat(new \FFMpeg\Format\Video\X264)
  
      ->save('small_steve.mp4');

  How can access file from s3 bucket and convert ?

• Returned non-zero exit status 1 / error code 1 : b''

  I’m trying to extract the video height via ffprobe into python, however I am having issues (with some videos).

  Here is my ffprobe command : ffprobe -v quiet -print_format compact=print_section=0:nokey=1:escape=csv -show_entries stream=height "some video here(bla)_25.mp4"

  It returns something like this

  720
  
  (empty-line)
  
  N/A

  Here is the code I used to extract the output for later processing :

  executecommand = 'ffprobe -v quiet -print_format compact=print_section=0:nokey=1:escape=csv -show_entries stream=height "' + CurrentVideoToBeProcessed + '"'
  
  
  
  VideoHeight = subprocess.check_output(executecommand)

  This is the error that came about :

  subprocess.CalledProcessError : Command ’...’ returned non-zero exit
  status 1

  So when I modified the code to this :

  try:
  
      VideoHeight = subprocess.check_output(executecommand,shell=True,stderr=subprocess.STDOUT)
  
  except subprocess.CalledProcessError as e:
  
      raise RuntimeError("command '{}' return with error (code {}): {}".format(e.cmd, e.returncode, e.output))

  This is the error I get :

  RuntimeError : command ’...’ return with error (code 1) : b’’

  I assumed at first the issue was with the file names, but certain videos work and certain don’t, irregardless of the file name.
  This is the output I get in python for videos that work :

  b’360\r\n\r\n’

  Any idea what’s going on ? Thanks !

  Edit
  It turns out the problem is in the file names after all. From what I gather so far at least, numbers in file-names seem to be causing the error.
  Edit2
  I re-ran the code after I closed several cmd instances and I am not getting the error anymore. I don’t know why. I am sure, however that if I were to convert hundreds of videos again I’ll get the error eventually as it has always happened eventually.
