• OSError : [Errno 9] Bad file descriptor when downloading using pytube and playing with discord.py

  15 septembre 2022, par Trevor Mathisen

  When using pytube to download a YouTube video and discord.py to play it, I am getting a OSError : [Errno 9] Bad file descriptor error. I've had this working at one point and can't seem to figure out what I changed which broke it.

  I've mounted the /media/ dir during docker -v and can see the file is getting downloaded and when I copy the file to my local machine I can play it in an audio player.

  


  The program can access the SQLite database right next to the files in question just fine.

  


  I've deployed the container locally and to two different VPS's with the same file structure with the same behavior. I'm ripping my hair out.

  


• facing problem in downloading the audio data of a trimmed youtube video using youtube-dl and ffmpeg libraries

  15 mai 2022, par rkc

  I'm trying to download the audio content of a trimmed YouTube video using youtube-dl (v2021.12.17) and FFmpeg (v4.2.2) libraries in python, on Windows 10 PC. I am able to download the audio data when the command is executed on the Pycharm terminal, but not able to download the same content when using os.system() command.

  


  For example, I'm able to download the data when I execute

  


  "ffmpeg -ss 30 -t 10 -i $(youtube-dl -f best -g https://www.youtube.com/watch?v=3NGZcpAZcl0) -- output1.wav"


  


  command on the Pycharm terminal.

  


  But, i'm getting an error, when I try to execute the same in the Editor window as shown below,

  


  os.system('ffmpeg -ss 30 -t 10 -i $(youtube-dl -f best -g https://www.youtube.com/watch?v=3NGZcpAZcl0) -- output1.wav')

error: $(youtube-dl: No such file or directory


  


  I also tried enclosing the $() link in quotes and then executed it. But, after doing this, I am getting a different error as shown below

  


  os.system('ffmpeg -ss 30 -t 10 -i "$(youtube-dl -f best -g https://www.youtube.com/watch?v=3NGZcpAZcl0)" -- output1.wav')

error: $(youtube-dl -f best -g https://www.youtube.com/watch?v=3NGZcpAZcl0): Invalid argument


  


  So, can any of you help me in resolving this error ?

  


• How easy is it to create a YouTube to MP3 application using yt-dlp and ffmpeg ?

  26 juin 2022, par fowlis

  I was thinking I could automate the process of downloading a video and converting it to mp3 (or other formats).
  
Instead of doing the process myself (which doesn't take that long and isn't too much hassle), which looks something like this :
  
• yt-dlp https://www.youtube.com/watch?v=dQw4w9WgXcQ
  
• wait for download then (find and) rename file to something simpler for next command
  
• ffmpeg -i video.mp4 video.mp3

  

  


  I thought I could turn it into a simple JS (or other language) program instead, where it :
  

  


  

  1. Asks for link and what format I want it in

  


  2. Downloads the video

  


  3. Renames it (not sure how easy this is)

  


  4. Turns it into requested format

  


  5. Opens file location

  


  


  If something like this is possible, please let me know some things I should know since I've never written a windows app before, and some general guidance for how I could do this.

  
I apologise if questions like this aren't exactly allowed on this site, its my first time posting too.
  
Thanks in advance !
