DiscordJS Music Bot Connects and Then Immediately Disconnects From Voice Channel
23 janvier 2020, par კΙбthebraɨɴsI see that questions similar to this one have been asked, and after following their solutions I still end up the same as I started. Below I have listed my code, a link to test it with a sample bot I created, and the modules you will need to test it using a self-hosted instance.
My problem is that upon connecting to the specified voice channel, the bot immediately leaves afterwards without any signs of errors or exceptions. I’m not sure if it is a problem with my code, or with one of the libraries I am using. The only console output I receive is as follows :
Bot Ready For Use

left channelThanks !
My Code
var voiceChannel = message.member.voiceChannel;
if (!message.member.voiceChannel) return message.channel.send(`You do realize you have to be in a voice channel to do that, right ${message.author.username}?`)
if (!message.member.voiceConnection) voiceChannel.join().then(async connection => {
let streamURL = args.slice(1).join(" ")
let streamTitle = "";
let streamThumb = "";
let streamAuth = "";
let streamAuthThumb = "";

FFMpeg C++ encoder fails with hardware acceleration quick sync intel
28 août 2022, par tealsI am trying to debug an issue I have with a simple C++ encoder using FFMmpeg. The following code below works correctly on these other hardware acceleration systems/platforms :


- 

- Mac/VideoToolbox,
- Cuda/NVEnc
- Raspberry pi/h264_v4l2m2m.








It fails on intel quick sync at
avcodec_open2. I'm using Ubuntu 22.04. I built FFMpeg from source with the Intel Media SDK installed and configured. I verified that the QuickSync install works. I also have a corresponding decoder implementation that works correctly using intel quick sync. So I know everything properly installed. I am also running this on an 11th Gen Intel CPU.

[hevc_qsv @ 0x564b0d34f0c0] Low power mode is unsupported (This sometimes shows up)
[hevc_qsv @ 0x563691234000] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


This is the only error that I get and I haven't found any helpful resources. I tried playing around with different parameters but nothing seems to work. Any help or insight would be extremely helpful.

FFmpegPCMaudio doesn't work on my server but it works on my computer
4 mai 2023, par AlexI am developing a Discord bot with python that can play music. When I do the tests on my computer all work find but when I take all the files to put there in my server it stop working. So I tried to run it on an other computer and no, it still does not work.


First I was thinking it was a power problems but the other computer is almost the same. I tried to install all the packages that I have on my computer to the second but the music part still not work. It's not a Discord API problem because my others commands work find.


import discord
from discord.ext import commands
from youtube_dl import YoutubeDL

 # all the music related stuff

 self.is_playing = False

 query = " ".join(args)

 voice_channel = discord.utils.get(ctx.guild.voice_channels, name='General')
 if voice_channel is None:
 # you need to be connected so that the bot knows where to go
 await ctx.send("Connect to a voice channel!")
 else:

 if type(song) == type(True):
 await ctx.send(
 "Could not download the song. Incorrect format try another keyword. This could be due to playlist or a livestream format.")
 else:
 await ctx.send("Song added to the queue")
 self.music_queue.append([song, voice_channel])

 if self.is_playing == False:
 await self.play_music()

 async def q(self, ctx):

 print(retval)
 if retval != "":
 await ctx.send(retval)
 else:
 await ctx.send("No music in queue")

 @commands.command(name="skip", help="Skips the current song being played")
 async def skip(self, ctx):

 if voice.is_playing():
 voice.pause()
 else:
 await ctx.send("Currently no audio is playing.")

 @commands.command(name="resume")
 async def resume(self, ctx):
 voice = discord.utils.get(self.bot.voice_clients, guild=ctx.guild)
 if voice.is_paused():
 voice.resume()
 else:
 await ctx.send("The audio is not paused.")


There are not any error messages, the bot just joins the voice chat and does nothing.


If someone can tell me we it work just on my computer I will be very grateful.
