• Why i'm failing to download mp4 file using youtube-dl in python

  9 décembre 2019, par Joao

  Python noob :(

  I created a script that downloads any youtube video.

  Then the script inserts a subtitle into the video and that works fine.

  However, I have a problem, I can’t make the script always download the video in mp4. Most of the time it is downloaded in mkv and i can’t understand why that happens and how can I change the code in order to always download the video in the format I prefer.

  The function in charge to download the video is this one :

  def video_download():
  
      #global resolution
  
      try:
  
          print(linkvideo)
  
          ydl_opts = {
  
              'format': 'bestvideo[ext=mp4]+bestaudio/best',
  
              'outtmpl': video_id+"."+'%(ext)s'
  
              #'bestvideo': 'mp4',
  
              #'bestaudio': 'm4a',
  
              #'ext': 'mp4'
  
          }
  
          with youtube_dl.YoutubeDL(ydl_opts) as ydl:
  
              ydl.download([linkvideo])
  
              result = ydl.extract_info("{}".format(linkvideo))
  
              title = result.get("id", None)
  
              videoext = result.get("ext", None)
  
              resolution = result.get("resolution", None)
  
      except:
  
          print("falhou")
  
          pass
  
      global ficheiro
  
      ficheiro2 = str(title)+"."+"mkv"
  
      ficheiro =""
  
      for i in ficheiro2:
  
          if (i == '"' or i =="'" or i =="/"):
  
              pass
  
          else:
  
              ficheiro += i

  Can any one help me ? Thanks in advance.

  I got it, thanks to everyone who tried to help me.

  The problem is this : when we try to download any video with the opts i’ve selected, youtube-dl will download the best video/audio combination in the same file, so I’ve added the following in my code :

  ytdl = YoutubeDL()
  
      result = ytdl.extract_info(linkvideo, download=False)
  
      formats = result['formats']
  
      formato = ""
  
      formatoaudio =  ""
  
      extaudio = ""
  
      for format in formats:
  
          if format['format_note'] == "1080p" and format['ext'] == "mp4":
  
              print(format)
  
              formato = (format['format_id'])
  
              break
  
          else:
  
              print("no 1080p mp4?!")
  
  
  
      if formato == "":
  
          for format in formats:
  
              if format['format_note'] == "720p" and format['ext'] == "mp4":
  
                  print(format)
  
                  formato = (format['format_id'])
  
                  break
  
              else:
  
                  print("no 720p mp4")

  Then I did the same to the sound file, checking if there is any m4a or webm sound file. To finish I’m joining both files using FFmpeg.

  Maybe this is not the best solution, but I’m still learning. :)

  Thank you all

• Download from sites that require a login using ffmpeg

  I want to download HLS videos from a site that needs to be logged in using FFmpeg, meaning I have to enter my username and password to access the videos, and I do not know how to enter the login information through FFmpeg...
Can anyone help me ?
