• Python Discord music bot stops playing a couple of minutes into any song

  9 mars 2023, par knewby

  I am trying to put together a Python Discord music bot as a fun little project. Outside of the required discord library I'm currently using the YouTube API to search for videos and parse the URL (not shown in code), yt-dlp which is a fork of yt_download that is still maintained to get the info from the YT URL, and FFMPEG to play the song obtained from yt-dlp through the bot. My play command seems to work as the 1st YT video result will start to play, but roughly 30-90 seconds into the audio, it stops playing. I get this message in the console :

  


  2023-02-23 14:54:44 IN discord.player ffmpeg process 4848 successfully terminated with return code of 0.

  


  So there is no error for me to go off of. I've included the full output from the console below...

  


  -----------------------------------
groovy-jr#6741 is up and running
-----------------------------------
2023-02-23 14:53:23 INFO     discord.voice_client Connecting to voice...
2023-02-23 14:53:23 INFO     discord.voice_client Starting voice handshake... (connection attempt 1)
2023-02-23 14:53:24 INFO     discord.voice_client Voice handshake complete. Endpoint found us-south1655.discord.media
2023-02-23 14:54:44 INFO     discord.player ffmpeg process 4848 successfully terminated with return code of 0.  <= AUDIO STOPS


  


  I'm currently developing this project on a Windows 11 machine, but I've had the issue running it on my Ubuntu machine as well. I am just hosting the bot directly from the VSCode terminal for development.

  


  I've been trying to do research on this problem, the problem is I can't find many recent information for the issue. There was another post that talked about a similar problem and had an answer suggesting the following FFMPEG options be used which I tried to no avail.

  


  FFMPEG_OPTIONS = {
                    'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
                    'options': '-vn',
                 }


  


  I'll include the problem file below :

• How to use multiple cookies in FFmpeg ?

  17 mai 2023, par カルロサグ

  I am trying to use cookies in ffmpeg to download a video that requires cookies

  


  I checked the documentation for multiple cookies using the "-cookies" argument, they must be separated by a newline, but the docs don't show an example of how to do it, there is only an example for the cookies syntax using a single cookie. I've tried "\n" and "\r\n" (used by the "-headers" argument) and they didn't work : I get a 403 response error

  


  Using a regular HTTP client such as curl or aiohttp (python) downloads the video, so the cookies and headers I provided are correct

  


  First test : Cookies as headers
