• Fail to play videos using ffplay in concat protocol

  13 janvier 2017, par Jian Guo

  I was trying to play multiple videos online using ffplay with concat protocol. According to the Documentation I tried this command in my terminal :

  ffplay -safe 0 -protocol_whitelist file,http,https,tcp,tls,concat concat:http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear1/prog_index.m3u8\|http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear2/prog_index.m3u8

  But it fails to play those two videos :

  Error when loading first segment 'concat:http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear1/prog_index.m3u8|http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear2/fileSequence0.ts'
  
  concat:http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear1/prog_index.m3u8|http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear2/prog_index.m3u8: Invalid data found when processing input

  I searched the error for a while but found nothing helps. Any ideas ?

• 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:

        channel = ctx.message.author.voice.channel
        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.")

@client.command(pass_Context = True)
async def resume(ctx):
    voice = discord.utils.get(client.voice_clients, guild = ctx.guild)

        await ctx.send("My ears are bleeding")
        voice.resume()

async def play(ctx, arg):
    await ctx.send("Playing..")
    voice = ctx.guild.voice_client
    source = FFmpegPCMAudio(arg)

  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)
