• Python script and equivalent command do not run the same

  19 août 2021, par user32882

  I would like to use youtubedl to download the audio from a YouTube video into an mp3 file. I came up with the following command to do so :

  


  youtube-dl -x --audio-format mp3 https://www.youtube.com/watch?v=SF8DGbfOFig&ab_channel=derang

  


  When I run the above command through my command line, it seems that I successfully manage to download the file in mp3 format :

  


  [youtube] SF8DGbfOFig: Downloading webpage
[download] Destination: Total Science & S.P.Y - Piano Funk (Ft. Riya & DāM FunK) [320k]-SF8DGbfOFig.webm
[download] 100% of 5.57MiB in 00:03
[ffmpeg] Destination: Total Science & S.P.Y - Piano Funk (Ft. Riya & DāM FunK) [320k]-SF8DGbfOFig.mp3
Deleting original file Total Science & S.P.Y - Piano Funk (Ft. Riya & DāM FunK) [320k]-SF8DGbfOFig.webm (pass -k to keep)


  


  I then tried to convert the above command to an equivalent python script as follows :

  


  import youtube_dl
links = ["https://www.youtube.com/watch?v=SF8DGbfOFig&ab_channel=derang"]
ydl_args = {
        'audioformat': 'mp3',
        'outtmpl': '%(title)s.%(ext)s',
        'extractaudio': True
    }
with youtube_dl.YoutubeDL(ydl_args) as ydl:
    results = ydl.download(links)


  


  However, this does not succeed in generating an mp3 file of the audio. These are the logs I am getting :

  What am I doing wrong here ? Aren't my command and python script equivalent ?

• SETX is not recognized as an internal or external command operable program or batch file [duplicate]

  6 avril 2020, par anonymous

  (skip this paragraph if you don't care about context) : So I was trying to record inside of Minecraft using the replay mod, and to render a video I have to install this thing called ffmpeg to render it, and my fears were correct, SETX is not recognized.

  



  So, a while back I had to redo my javac because that wasn't recognized, but when I did get that fixed, it made all my other commands toast, except the basic ones like "copy" or "del". I don't know how, I'd assume I'd need to manually input the path variable and everything because I doubt I could even find anything in the system variables for it, but that may not be the case. Suggest some YouTube vids, or a thorough and non-complicated explanation if you can, because for some reason, some instructions go through one ear and out the other.

  



  I also posted this in /r/feedthebeast, but I doubt anyone will find a solution there.

  



  Thanks.
