  • I cannot play a mp3 file on Discord's voice channel using discord.py

    1er décembre 2024, par ra1ned

    I am creating a discord bot that plays lofi for me. It does not play a song for me even though it shows a green indicator on a voice channel.

    


    Here's what I've written :

    


    if message.content == "!join":
    await message.author.voice.channel.connect()
    await message.channel.send("Successfully connected")

if message.content == "!play":
    if message.guild.voice_client is None: 
        await message.channel.send("use !join")
        return
    
    await message.channel.send("playing a song rn")
    print('*** playing a song rn')
    
    message.guild.voice_client.play(discord.FFmpegPCMAudio('lofi.mp3'))


    


    I put FFmpeg.exe and lofi.mp3 in the same directory as this script.
Also, it is strange that FFmpeg does not return any exception nor output on console although it seems to have failed to load the file. I have seen people who had the same problem, but it seems like that they get some error messages, unlike me.

    


    Here's the output on console after using !join

    


    2024-12-01 16:59:39 INFO     discord.voice_state Connecting to voice...
2024-12-01 16:59:39 INFO     discord.voice_state Starting voice handshake... (connection attempt 1)
2024-12-01 16:59:40 INFO     discord.voice_state Voice handshake complete. Endpoint found: japan8946.discord.media
2024-12-01 16:59:40 INFO     discord.voice_state Voice connection complete.


    


    after using !play, it only displays the message I wrote :

    


    *** playing a song rn


    


    Can someone help me with this ?

    How can I fix this error ?

    


    I read the
stack overflow

    


      

    1. Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height
