• Making youtube-dl download mp3's faster

  12 novembre 2017, par sciencelord

  It takes a long time to download mp3 songs using youtube-dl, and it takes even longer when downloading a bunch of mp3 songs. Is there a way to make it significantly faster ? I don’t mind reducing quality. I’ve been using the command below.

  youtube-dl --extract-audio --audio-format "mp3" --output "%(title)s.%(ext)s" "https://www.youtube.com/watch?v={videoid}

  I also took a look at this post :
  ffmpeg command for faster encoding at a decent bitrate with smaller file size

  But I wasn’t sure how to change the above command using the ffmpeg modifications.

  Thanks !

• No such file or directory when running an ffmpeg command from script

  23 novembre 2017, par A_Matar

  I have been trying to run this ffmpeg command from python script to generate video of certain length from a static image but I keep getting No such file or directory error !
  Here is my code :

  import subprocess
  
  
  
  def generate_white_vid (duration):
  
      ffmpeg_create_vid_from_static_img = 'ffmpeg -loop 1 -i /same_path/WhiteBackground.jpg -c:v libx264 -t %f -pix_fmt yuv420p -vf scale=1920:1080 /same_path/white_vid2.mp4' % duration
  
      print ffmpeg_create_vid_from_static_img
  
      pp = subprocess.Popen(ffmpeg_create_vid_from_static_img)
  
      pp.communicate()
  
  
  
  generate_white_vid(0.5)

  However when I run the same exact command :

  ffmpeg -loop 1 -i /same_path/WhiteBackground.jpg -t 0.500000 -pix_fmt yuv420p -vf scale=1920:1080 /same_path/white_vid2.mp4

  from the cli, it works just fine. Where am I missing up ?
  Here is the full trace :

  Traceback (most recent call last):
  
    File "gen.py", line 10, in <module>
  
      generate_white_vid(0.5)

      pp = subprocess.Popen(ffmpeg_create_vid_from_static_img)

      raise child_exception
  
  OSError: [Errno 2] No such file or directory
  
  </module>

  When I use a list to pass the ffmpeg commands parameters as following ffmpeg_create_vid_from_static_img = ['ffmpeg', '-loop', '1', '-i', '/same_path/WhiteBackground.jpg', '-c:v', 'libx264', '-t', duration, '-pix_fmt', 'yuv420p', '-vf', 'scale=1920:1080', '/same_path/white_vid.mp4'] , I get a type error :
