• Trying to use the arcade library on Python3 with Debian 10 errors with pyglet_ffmpeg

  30 mars 2020, par Colin

  I’ve been trying to use the arcade library this morning with python3 but keep getting nothing but errors.

  My environment is Debian 10 (buster)

  I checked first to ensure I have python 3 installed, this confirmed as Python 3.7.3

  I double checked (according to the arcade library website arcade linux installation instructions and ran the install for python3 to make sure that pip and the required libraries were installed.

  I then ran the command to install the library

  sudo pip3 install arcade

  And to test it, copied and pasted the happy_face.py example. However when I tried to run it I got a slew of errors. This seems to be directly related to the arcade installation and if I just run a python script (test.py) with just one line

  import arcade

  At the terminal with

  python3 test.py

  I get the following errors

  I have used the following terminal command to identify the version of OpenGL installed

  glxinfo | grep "OpenGL version"

  Which returned

  OpenGL version string : 3.3 (Compatibility Profile) Mesa 18.3.6

  I have also tried the terminal command

  sudo pip3 install pyglet-ffmpeg

  Which returns

  Requirement already satisfied : pyglet-ffmpeg in
  /usr/local/lib/python3.7/dist-packages (0.1.4)

  Requirement already satisfied : pyglet>=1.4.0a1 in
  /usr/local/lib/python3.7/dist-packages (from pyglet-ffmpeg) (1.5.0)

  Requirement already satisfied : future in
  /usr/local/lib/python3.7/dist-packages (from
  pyglet>=1.4.0a1->pyglet-ffmpeg) (0.18.2)

  Any assistance would be appreciated. I’ve tried to be as concise as I can, but if more information is required, I’ll gladly supply it.

• How do I use ffmpeg on linux for my discord music bot ?

  7 mars 2023, par Dio

  I made a discord music bot a while back for me and my friends to use(it is minimalistic), but I recently switched from windows to Linux. I was using FFMPEG for my bot(the .exe file was in the same folder as the code).
I'll leave the Github link to my bot down here :

  


  https://github.com/Dorian1997/Discord-Bot

  


  Now my question is, do I have an alternative to FFMPEG on Linux ? Or how exactly should I install FFMPEG for it to work right ? I already installed it from the terminal, yet it doesn't seem to work as the bot cannot play anything.
Thank you for your time !
