• Simple discord.py mp3 bot not playing music

  18 avril 2023, par Lukas Nesvarbu

  Discord bot dosent play anykind of music, neither mine nor other bots codes work he just dosent play music. idk maybe i am just stupid BUT IT DOSENT WORK WHY

  


  import discord
import time
import os
from discord.ext import commands

BOT_TOKEN = "" # put token here

intentss = discord.Intents.default()
intentss.message_content = True
intentss.voice_states = True

bot = commands.Bot(command_prefix=";;", intents = intentss)

OPUS_LIBS = ['libopus-0.x86.dll', 'libopus-0.x64.dll', 'libopus-0.dll', 'libopus.so.0', 'libopus.0.dylib']

@bot.command()
async def join(ctx):
    channelVC = ctx.author.voice.channel
    await channelVC.connect()

@bot.command()
async def leave(ctx):
    await ctx.voice_client.disconnect()

@bot.command()
async def play(ctx):
    voice = ctx.guild.voice_client
    mloc = 'C:/Users/Lukas/Desktop/Bot Bethoven/Youtube/test.mp3'
    voice.play(discord.FFmpegPCMAudio(executable = "C:/ffmpeg/bin/ffmpeg.exe", source = mloc))


bot.run(BOT_TOKEN)


  


  it just give error codes :

  


  discord.ext.commands.errors.CommandInvokeError: Command raised an exception: ClientException: Not connected to voice.
INFO     discord.player ffmpeg process 22896 has not terminated. Waiting to terminate...
INFO     discord.player ffmpeg process 22896 should have terminated with a return code of 1.


  


  intresting thing when i put join and play in the same command it dosent show not connected to voice error, actually it dosent show anything and neither plays mp3 file

  


  i tryed reinstalling : PyNaCl, FFmpeg, Visual Code, updating python.
nothing helps. this problem started after i did 1 month break from coding bot, before that it worked fine.

  


  i'm thinking problem is something with my pc, maybe path or something dosent work(because it worked month ago and i didnt do anything to code), i tryed checking but everything seems normal,

• Is there a simple way to create 8 or 16 bit grayscale videos using matplotlib ?

  19 avril 2022, par user18544920

  I have been reading for 3 days however still can't quite wrap my head around how to do the following. We have been asked to produce a simulation video from matplotlib to evaluate a programme that only accepts u8 or u16 grayscale videos. I have managed to produce the required animated scatterplot using the following code, however only know how to convert to grayscale using the second chunk of code in CV2 that results in a lot of compression.

  


  I would get marked down for both the heavy compression and not doing it within the animation code, however I don't know of a way to do it during the animation code.

  


  Animation code

  


  pixelx = 250  # length of x for resulting movie in pixels
pixely = 250  # length of y for resulting movie in pixels
fig2d = plt.figure(figsize=(pixelx/72, pixely/72), dpi=72)
ax2d = fig2d.add_axes([0,0,1,1])
ax2d.set_axis_off()
scatter2d = ax2d.scatter([], [], s=(pixelx*particle.rad/Env.X)**2, marker='o', edgecolors='none', c='#000000', cmap='gray')
ax2d.set_aspect('auto')
ani2d = FuncAnimation(fig2d, update2d, frames=(duration * fps), init_func=initial2d, blit=False, interval=1000/fps,
                      repeat=True)
ani2d.save('x.avi', writer='ffmpeg', fps=fps, dpi=72)


  


  RGB to grayscale code

  


  import cv2
source = cv2.VideoCapture('x.avi')
frame_width = int(source.get(3))
frame_height = int(source.get(4))
size = (frame_width, frame_height)
result = cv2.VideoWriter('xG.avi',
                         cv2.VideoWriter_fourcc(*'MJPG'), 200, size, 0)
while True:

    ret, img = source.read()

    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

    result.write(gray)

    cv2.imshow("frame", gray)

    key = cv2.waitKey(1)
    if key == ord("q"):
        break

cv2.destroyAllWindows()
source.release()


  


  Any help would be greatly apprciated
