• discord.py nextcord.py It cant read mp3 audio files

  23 février 2023, par hihihi hihihi

  I'm trying to make my discord bot speak some text, but I can't make it stream the generated mp3 audio file. I'm using Nextcord and FFmpeg.

  


  This is the code I run :

  


  @bot.command(name="bottalk")
async def bottalk(ctx, *args):
    text = " ".join(args)
    user = ctx.message.author
    if user.voice != None:
        try:
            vc = await user.voice.channel.connect()

        except:
            vc = ctx.voice_client   

        sound = gTTS(text=text, lang="en", slow=False)  
        sound.save("please read this.mp3")

        if vc.is_playing():
            vc.stop()

        source = await nextcord.FFmpegOpusAudio.from_probe("please read this.mp3", method="fallback")
        vc.play(source)
    else:
        await ctx.send("join vc")    


  


  When I run the code it generates the mp3 audio file but cannot play the audio file. I get this error :

  this is my music_cogs.py, this is where error is coming from

  I'm trying to capture with Spanish subtitle stream in the screen

  


  I tried :

  


  ffmpeg -ss 14 -copyts -i C:\MyVideo.mkv -map 0:0 -map 0:3 -codec copy -codec:3 mov_text -vframes 1 C:\test.png


  


  but is not working, means the PNG is not PNG actually. I don't know the format is output.

  


  How to capture screen with spanish subtitle (position 4 in mediainfo) ?
