• FFmpeg doesn't play audio, yet no error shown

  4 août 2023, par Kristupas

  So i'm learning Python and don't know much about FFmpeg. I am following a tutorial, which explains everything very clearly. Everything is working, with one exception. Whenever I try to get it to play a sound, it won't.. Here's what it is saying :

  


  INFO     discord.player ffmpeg process 2540 successfully terminated with return code of 1.

  


  And here's my code (forgive me for all of the childish things in there, i'm just trying out different features) :

  


  
import discord
import discord.ext
from discord import FFmpegPCMAudio
from discord.ext import commands
import random


Token = "No token for you :)"
client = commands.Bot(command_prefix = '!', intents=discord.Intents.all())


@client.event
async def on_ready():
    print(f"we're rolling as {client.user} \n")
    channel = client.get_channel(1022535885851459727)
    await channel.send("Tremble before my might hoomans😤😤")

#Member events:

@client.event
async def on_member_join(member):
    await member.send("Ok comrade, welcome to bot lab, pls not leave. Anways here rules \n1. No swearing \n2. No cursing \n3. No bullying, the owner is a crybaby \n4. No following the rules (u get banned if this one is broken)")
    channel = client.get_channel(1136658873688801302)
    jokes = [f"A failure known as {member} has joined this chat!", 
             f"Another {member} has joined the channel", 
             f"A {member} spawned", 
             f'cout << "{member} has joined teh chat" << endl;', 
             f"OUR great {member} has come to save us" ]
    await channel.send(jokes[random.randint(0,len(jokes))])

@client.event 
async def on_member_remove(member):
    await member.send("Bye our dear comrade")
    channel = client.get_channel(1136663317738442752)
    await channel.send(f"{member} has left the chat :(.)")

#Client commands:

    await client.process_commands(message)


#voice channel commands:

        voice = await channel.connect()
        source = FFmpegPCMAudio('Bluetooth.wav')
        player = voice.play(source)
        
        
        
    else:
        await ctx.send("No.")



@client.command(pass_Context = True)
async def leave(ctx):
    if (ctx.voice_client):
        await ctx.send(f"Leaving on {ctx.message.author}'s command")
        await ctx.guild.voice_client.disconnect()
    else:
        await ctx.send("Nyet. Im not in voice chat u stoopid hooman")


@client.command(pass_Context = True)
async def pause(ctx):
    voice = discord.utils.get(client.voice_clients, guild = ctx.guild)
    if voice.is_playing():
        await ctx.send("Pausing..⏸")
        voice.pause()
    else:
        await ctx.send("I don't think I will.")

    voice = ctx.guild.voice_client

  I tried installing different versions of ffmpeg, still nothing. I tried to run the code outside of my venv, but still nothing (i doubt that it's the problem). I changed the path to it to different folders, still nothing.
The only time it DID work is when i entered a full path, but then when you want to play something, you wouldn't want to say " !play D:_Python\DiscordBot\Bluetooth.wav". From what i've seen, it's possible to play it by just saying " !play Bluetooth.wav".

  


  So long story short : I want to make it so that the path i have to specify is just the file name. And when I do, it doesn't play the sound.
(sorry if this is a dupe question, i just couldn't find anything understandable for my amateur brain)

  


• Image mask blur processing problem using ffmpeg

  16 avril 2024, par andrew kim

  I want to apply blur using masking to two or more points in the image. I want to use a circular or other type of blur in ffmpeg rather than a box blur. I wrote the ffmpeg code, but an error continued. When there is only one blur, it works correctly, but when there are two or more blurs, an error occurs. No matter how much I search, I can't figure it out, so I'd like to ask for help.

  


  The ffmpeg code I wrote is as follows.

  


  ffmpeg -i input.mp4 -i mask.png -filter_complex "`
[1:v]scale=200:200,pad=1920:1080:(ow-iw)/1:(oh-ih)/1[pmask1]; `
[1:v]scale=200:200,pad=1920:1080:(ow-iw)/3:(oh-ih)/3[pmask2]; `
[0:v][pmask1]alphamerge,avgblur=10[alf];[0:v][alf]overlay[temp1]; `
[temp1][pmask2]alphamerge,avgblur=10[alf2];[temp1][alf2]overlay[v] `
"-map "[v]" -map 0:a -c:v libx264 -c:a copy -movflags +faststart maskedblur.mp4


  


  The error is as follows.

  


  [mov,mp4,m4a,3gp,3g2,mj2 @ 0000026ed1d4a500] Invalid stream specifier: temp1.
    Last message repeated 1 times

• Mask dynamic logo using ffmpeg

  15 juin 2014, par Francesco De Pazzi

  I am trying to detect and hide a logo that dynamically positioned in a video.

  In this video the logo is positioned at the top and after a few minutes down etc.

  it’s possible to detect every time the logo when it changes place and hide it with ffmpeg ?

  I tried with delogo but I must tell the position x/y, so it is not possible in my case !

  Thank you very much !
