discord.ext.commands.errors.CommandInvokeError : Command raised an exception : ClientException : ffmpeg was not found
22 juillet 2022, par MSTI 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 :

FFMPEG audio conversion is taking too much time
26 octobre 2018, par Sachin VarmaHow to make the audio conversion ultrafast ?
It is now taking more than 2 minutes for converting an audio around 2mb in size.
The command i’m using for execution of conversion is
String[] cmd = {"-y", "-i", audioPath, outputPath};How to preset the ultrafast mode ?
While i’m trying it like
String[] cmd = {"-y", "-i", audioPath,"-preset", "ultrafast" ,outputPath};It is taking same time itself.

How to play raw h264 produced by MediaCodec encoder ?
1er novembre 2014, par jackos2500I’m a bit new when it comes to MediaCodec (and video encoding/decoding in general), so correct me if anything I say here is wrong.
I want to play the raw h264 output of MediaCodec with VLC/ffplay. I need this to play becuase my end goal is to stream some live video to a computer, and MediaMuxer only produces a file on disk rather than something I can stream with (very) low latency to a desktop. (I’m open to other solutions, but I have not found anything else that fits the latency requirement)
Here is the code I’m using encode the video and write it to a file : (it’s based off the MediaCodec example found here, only with the MediaMuxer part removed)

</p>However, the file produced from this code does not play with VLC or ffplay. Can anyone tell me what I’m doing wrong ? I believe it is due to an incorrect format (or total lack) of headers required for the playing of raw h264, as I have had success playing .264 files downloaded from the internet with ffplay. Also, I’m not sure exactly how I’m going to stream this video to a computer, so if somebody could give me some suggestions as to how I might do that, I would be very grateful ! Thanks !
