• ffmpeg, stereo + 5.1 surround, and YouTube's "Recommended upload encoding settings"

  31 juillet 2021, par CoreyVidal

  I'm trying to make sense of something YouTube has listed on their recommended upload encoding settings for the best possible quality. Here's the link : https://support.google.com/youtube/answer/1722171#zippy=%2Caudio-codec-aac-lc

  


  Specifically this line :

  


  


  

  • Channels : Stereo or Stereo + 5.1

  


  


  


  I'm Googling for "Stereo + 5.1" and anything to do with ffmpeg but I can't seem to find much of anything.

  


  I have trailers with surround audio I need to export for a client for YouTube.

  Hello I am setting up streaming box that will be using a USB webcam as my video source and I am wanting to add in background audio to the live streams. I am wanting to do this by specifying a playlist and have it play through the audio files and then loop back once the playlist is finished. I have the ffmpeg command that allows me to stream the USB webcam and I can get one audio file to play but I can’t get seem to figure out how to get the playlist to work. Any help would be great.

• How do install ffmpeg in android for youtube-dl

  21 novembre 2019, par Wasp Nesser

  I have got a python code for downloading a video (from youtube) and converting to mp3. I used youtube-dl for these. Python code works in computer. But that error occurred in my android :

  youtube_dl.utils.DownloadError: ERROR: ffprobe/avprobe and ffmpeg/avconv not found. Please install one. [Program finished]

  I couldn’t find how to install these requirments in android . I use application called pydroid3 for executing python codes , installing python libraries and terminal staff. I tried to install ffmpeg and ffprob libraries with pip .But it didn’t helped me. After I tried to execute

  adb shell pm install ffmpeg 

  And It didn’t helped me to.

  This is my code :

  import youtube_dl
  
  import os 
  
  outtmpl = "%(playlist_title)s-%(playlist_uploader)s /%(playlist_index)s %(title)s-%(uploader)s.%(ext)s"
  
  ydl_opts = {
  
      'format': 'bestaudio/best',
  
      'postprocessors': [{
  
          'key': 'FFmpegExtractAudio',
  
          'preferredcodec': 'mp3',
  
          'preferredquality': '192',
  
      },
  
          {'key': 'FFmpegMetadata'},
  
      ],
  
      'outtmpl' : outtmpl,
  
  }
  
  
  
  url = input("Enter url : ")
  
  
  
  with youtube_dl.YoutubeDL(ydl_opts) as ydl:
  
  
  
      ydl.download([url])
