• discord.ext.commands.errors.CommandInvokeError : Command raised an exception : ClientException : ffmpeg was not found

  22 juillet 2022, par MST

  I made a music bot on Replit but, when running my code I get this error :
discord.ext.commands.errors.CommandInvokeError : Command raised an exception : ClientException : ffmpeg was not found.

  


  Can someone help me fix this ?

  


  main.py

  


  import discord
from discord.ext import commands
import music

cogs = [music]

client = commands.Bot(command_prefix='!', intents = discord.Intents.all())

for i in range(len(cogs)):
  cogs[i].setup(client)


client.run("token")


  


  music.py

  


  import discord
from discord.ext import commands
import youtube_dl
import ffmpeg

class music(commands.Cog):
  def __init__(self,client):
    self.client = client

  @commands.command(name="join")
  async def join(self,ctx):
    if ctx.author.voice is None:
      await ctx.send("You are not in a Voice Channel!")
    voice_channel = ctx.author.voice.channel
    if ctx.voice_client is None:
      await voice_channel.connect()
    else:
      await ctx.voice_client.move_to(voice_channel)

  @commands.command(name="disconnect")
  async def disconnect(self,ctx):
    await ctx.voice_client.disconnect()

  @commands.command(name="play")
  async def play(self,ctx,url):
    ctx.voice_client.stop()
    FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    YDL_OPTIONS = {'format':"bestaudio"}
    vc = ctx.voice_client

    with youtube_dl.YoutubeDL(YDL_OPTIONS) as ydl:
      info = ydl.extract_info(url, download=False)
      url2 = info['formats'][0]['url']
      source = await discord.FFmpegOpusAudio.from_probe(url2,**FFMPEG_OPTIONS)
      vc.play(source)


  @commands.command(name="pause")
  async def pause(self,ctx):
    await ctx.voice_client.pause()
    await ctx.send("Paused Playing Music!")

  @commands.command(name="resume")
  async def resume(self,ctx):
    await ctx.voice_client.resume()
    await ctx.send("Resumed Playing Music!")

def setup(client):
  client.add_cog(music(client))


  


  So, The bot is able to join the Voice Channel but when I ask it to play a song, it gives this error :

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

• How do I make libavformat reconnect when connection is reset by peer ?

  6 mai 2024, par user24897675

  I am opening a network file via HTTPS like this :

  


  avformat_open_input(&m_format, "https://www.example.com/file.mp4", nullptr, nullptr);


  


  It works, however sometimes connection is closed and this is logged :

  


  [tls @ 0x7f600ba690] Error in the pull function.
[tls @ 0x7f600ba690] IO error: Connection reset by peer
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f6007e450] Packet corrupt (stream = 0, dts = 24188928).
[aac @ 0x7f60324800] Input buffer exhausted before END element found


  


  I found it possible to setup reconnection by logs from this post. Here are their logs :

  


  [tls @ 0x6e3b440] Error in the pull function.
[tls @ 0x6e3b440] IO error: Connection reset by peer
[https @ 0x6e37900] Will reconnect at 720896 in 0 second(s), error=Connection reset by peer.


  


  Here libavformat does not give up and it tries to reconnect because -reconnect argument was passed in FFmpeg CLI. How can I do the same in code with FFmpeg's libavformat ?

  


• Merge mp3 files at specific duration in Android

  18 mai 2017, par Gio Vanno

  First I’m new in Android.

  I’m trying to make an app that can combine a lot of music(mp3 files im using) at specific duration with the selected music via seekbar.

  My main plan is to merge multiple audio files at specific time.

  example :
  when i pressed the drum button at 5 sec(via seekbar), and then guitar button at 6 sec.

  when i clicked the merge button, it will merged the selected mp3 file with those 2 mp3 files at their respective time.

  from what i’m searching so far, the possible way is by using ffmpeg from this :

  -How to overlay two audio files using ffmpeg

  -Merge mp3 files using FFmpeg on Android

  but i don’t see them merged at specified time.

  maybe there’s another way besides ffmpeg,or i’ve missed something ?

  thank you
