• avcodec/acelp_pitch_delay : Inline small functions only used once

  18 février 2021, par Andreas Rheinhardt

  avcodec/acelp_pitch_delay : Inline small functions only used once
  ff_acelp_decode_8bit_to_1st_delay3, ff_acelp_decode_4bit_to_2nd_delay3
  
  and ff_acelp_decode_5_6_bit_to_2nd_delay3 are all only used once (by
  
  g729dec) whereas ff_acelp_decode_9bit_to_1st_delay6 and
  
  ff_acelp_decode_6bit_to_2nd_delay6 are completely unused ; with the
  
  possible exception of ff_acelp_decode_4bit_to_2nd_delay3, these
  
  functions are so small that inlining them is appropriate ; and as long as
  
  ff_acelp_decode_4bit_to_2nd_delay3 is only called once, this is also
  
  true for it.

• Small discord bot with a set of working music commands, about 6 days ago the play function completely stopped functioning (more below)

  24 février 2021, par TheColoradoKid

  It is a small discord python bot for my server with various features, which had included music commands until they stopped out of the blue without showing any error for the problem.
It uses FFMpeg, and youtubeDl along with pytube to gather the song and store it locally to play it, I have pip updated all of these and they are definitely on the current versions as I have made sure of this online.
Any help or insight anyone could provide would be greatly appreciated. I'm sorry if the code is convoluted in the way it's written I'm still pretty new to coding and this is one of my first proper larger projects.

  


  If you need any information I'm happy to give what I can to help.

  


  Here is the code for the play command :

  


  @client.command()
async def play(ctx, *args):
    global queu
    #global autom
    if not args:
        voice = get(client.voice_clients, guild=ctx.guild)
        if not voice.is_playing():
            server = ctx.message.guild
            voice_channel = server.voice_client
            if queu:
                async with ctx.typing():
                    player = await YTDLSource.from_url(queu[0], loop=client.loop)
                    voice_channel.play(player, after=lambda e: print('Player error: %s' % e) if e else None)

                await ctx.send('**Now playing:** {}'.format(player.title))
                del(queu[0])
                # while autom == True:
                #     try:
                #         a = client.get_command('auto')
                #         await ctx.invoke(a)
                #     except:
                #         print('')
            elif not queu:
                await ctx.send("You can't play if there isn't anything in the queue\nIf auto mode was on it has now been disabled, to use it gain please add to the queue and run ``;auto on``")
                autom = False
    if args:
        global gueu
        search_keywords = ""
        print(args)
        for word in args:
            search_keywords += word
            search_keywords += '+'
        link = "https://www.youtube.com/results?search_query="
        link += search_keywords
        #print(link)
        html = urllib.request.urlopen(link)
        video_ids = re.findall(r"watch\?v=(\S{11})", html.read().decode())
        url = ("https://www.youtube.com/watch?v=" + video_ids[0])
        #print(url)
        queu.append(url)
        #print(queu)
        await ctx.send("``{}`` added to queue!\n If the song doesn't start please either let the current song end and run ``;play``/``;next`` again or run ``;next`` to play now".format(url))
        try:
            p = client.get_command('play')
            await ctx.invoke(p)
        except:
            print('failed')
