• 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 14:54:44 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 :

  I appreciate any guidance I can get !

  


• Keep getting "discord.ext.commands.errors.CommandInvokeError : Command raised an exception : KeyError : 'source'" error

  Everytime I try to run play command in my bot, I get this error in the terminal, kind of new to coding so not exactly sure whats going on. It was working just fine, then it started not to work.

  this is my music_cogs.py, this is where error is coming from

  


  was working just fine then it started to give me this error after a while.

The above exception was the direct cause of the following exception:

• What is the best way to get duration of a video using ffprobe (ffmpeg) ?

  15 juin 2023, par promaxdev

  Most of the solutions to get duration revolves around parsing the output to get the duration. Even FFProbe official documentation here says that there is no duration stored for MKV, webm, etc.

  


  Take the below examples.

  


  ffprobe -v error -i <inputmkv> -show_entries stream=...,duration,.. -of default=noprint_wrappers=1&#xA;</inputmkv>

  


  This gives me the below output. This is not having duration.

  


  

  


  But when I run the same command differently like below, I am getting this output but having duration. Just removed '-v error' part.

  


  ffprobe -i <inputmkv> -show_entries stream=...duration,... -of default=noprint_wrappers=1 &#xA;</inputmkv>

  


  

  


  If you notice the same command shows the duration in one place and not in another place.

  


  So my question is, What is the best way to get duration in ffmpeg, especially for the video streams ?

  


  Edit : I have already explored decoding using null mux option. But that is a costly operation and also need to parse the output.
