Make Discord bot play sound from a direct url
20 septembre 2020, par merctraiderI want to make a discordpy bot that plays audio files from a specific link on the internet, rather than from a local directory. It seems that all the other examples use ytdl, but those are for video streaming sites. How should I go about doing this ?


if(voice_channel != None):
 vc = await voice_channel.connect()

 vc.play(discord.FFmpegPCMAudio('http://website/001.mp3'), after=lambda e: print('done', e))
 else:
 await ctx.send("Join a voice channel first.")```

Pims.open Throws "UnkownFormat Error" with "Invalid Argument" On One Machine But Not on Another
12 août 2021, par KaceBellamyI'm trying to do some video processing for a physics experiment, and I want to do it on my much more powerful Windows desktop computer as opposed to my Mac laptop.


The following code works like a dream when run as a Jupyter notebook on my Mac :


import matplotlib as mpl
from mpl_toolkits import mplot3d
import pims
import trackpy as tp 

@pims.pipeline
def gray(image):
 return image[:, :, 1] # Take just the green channel

frames = gray(pims.open('output.mp4'))


but on my Windows machine I get this error :


---------------------------------------------------------------------------

output.mp4 is just a run of the mill video file taken on a CCD camera ; I've tried converting it to a .MOV, I've tried other video files taken on different cameras, and I've tried running the file through FFmpeg to impose a 30 fps framerate ; everything I've tried works fine on my Mac and throws the above error on my Windows machine.


For reference, I installed necessary packages for this code on both machines this morning, so it should all be up to date and the same on both.


Any ideas as to what's up ? Thanks !

How to play sound with a music discord bot on heroku
25 janvier 2020, par Eduardo EspinozaI’m creating a Discord Music Bot in discord.js, I already installed ffmpeg, and everything seems to work normally, but when I execute play command, bot joins a channel, send a message, but doesn’t play anything, I’ve already checked console and it doesn’t log anything.
I know it’s not a problem with code since it works perfectly locally, the problem is when I try to use heroku, I thought it could be a opusscript problem but I don’t know.
