• voice_client.play doesn't continue loop (Discord) (Solved)

  19 mars 2023, par Razurio

  SOLVED see end

    await empty_queue(songs)
    await ctx.reply('Stopped')

async def empty_queue(songs):
    while not songs.empty():
        songs.get_nowait()


  


  I have problems with the "await ctx.voice_client.play(discord.FFmpegPCMAudio(filename))" which doesn't continue after finishing.

  


  I know you can use a after= parameter in voice_client.play() but I didn't manage to get it to work to recursivly call queue()

  


  async def play_next(ctx):
global songs
global currently_playing
if songs.empty():
    currently_playing = False
    await ctx.reply("Queue is now empty")
    await ctx.voice_client.disconnect()  # disconnect from voice channel when queue is empty
else:    
    song = await songs.get()
    filename = song["file"]
    voice_channel = ctx.author.voice.channel
    if not ctx.voice_client:  # check if bot is not already connected to a voice channel
        await voice_channel.connect()

    def after(error):
        if error:
            print(f'Error in after callback: {error}')
        asyncio.create_task(play_next(ctx))

    await ctx.reply('playing')
    ctx.voice_client.play(discord.FFmpegPCMAudio(filename), after=after)


  


  I tried using the after parameter like like but I just get an error in line 116, in after asyncio.create_task(play_next(ctx)) "no running event loop" ... "Calling the after function failed"

  


  EDIT

  


  async def play_next(ctx):
global loop
global songs
global currently_playing
global tasks
loop = asyncio.get_event_loop()
if songs.empty():
    currently_playing = False
    await ctx.reply("Queue is now empty")
    await ctx.voice_client.disconnect()  # disconnect from voice channel when queue is empty
else:
    
    song = await songs.get()
    filename = song["file"]
    voice_channel = ctx.author.voice.channel
    if not ctx.voice_client:  # check if bot is not already connected to a voice channel
        await voice_channel.connect()
    def after(error):
        if error:
            print("er")
        loop.create_task(queue(ctx))

    await ctx.reply('playing')
    ctx.voice_client.play(discord.FFmpegPCMAudio(filename), after=after)


  


  using loop = asyncio.get_event_loop() and loop.create_task(queue(ctx)) made it finally work
took inspiration from this post

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

  


  was working just fine then it started to give me this error after a while.

• Pydub wma to mp3 fixing "library configuration mismatch"

  21 juillet 2020, par Rich

  Python novice, looking to change that.

  


  I am trying to convert a song from wma to mp3 while keeping the metadata on the song. Here is my code.

  


  #musicproject.py
import os
import glob
from pydub import AudioSegment

music_dir ='/mnt/c/renameproject'
extension_list = ('*.wma')

os.chdir(music_dir)
for extension in extension_list:
    for song in glob.glob(extension):
        mp3_filename = os.path.splitext(os.path.basename(song))[0] + '.mp3'
        AudioSegment.from_file(song).export(mp3_filename, format='mp3')


  


  The program finishes and the song is written as an mp3 in the same folder and plays just fine. Unfortunately all of the metadata has been stripped from the song. I get the following warning at the command line when I run the program. My theory on the problem is that there is a mismatch between pydub and ffmpeg as far as the metadata library goes so pydub is feeding in something that ffmpeg doesn't understand so it pukes. I have absolutely no idea what steps to take to fix it from here. Any breadcrumbs would be appreciated. Thanks.
