• 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')


  


• Merge (video and audio) with (background music) with ffmpeg

  9 mars 2021, par Sudesh

  I have video file input.mp4 that contain video and two audio source - speaking, and music.mp3 that contain background music. Now, I want to merge them.

  


  Here is the command that i use :

  


  ffmpeg -i input.mp4 -i music.mp3 -c:v copy -filter_complex "[0:a]aformat = fltp:44100:stereo,apad[0a];[1] aformat=fltp:44100:stereo,volume=1.5[1a];[0a] [1a] amerge[a]" -map 0:v -map "[a]" -ac 2 -y -shortest output.mp4


  


  input file
https://d9f35555a8b3e9044c8d-95c21efaab8093d23d4124e599a618ee.ssl.cf5.rackcdn.com/mub_audio/1e03dc67-5079-46d5-b692-d69bbb6ee3e3.mp4

  


  audio file
https://d9f35555a8b3e9044c8d-95c21efaab8093d23d4124e599a618ee.ssl.cf5.rackcdn.com/mub_audio/a6cab88a63eb11eb8d8b901b0efa6f1d.mp3

  


  you can check the output file here
https://d9f35555a8b3e9044c8d-95c21efaab8093d23d4124e599a618ee.ssl.cf5.rackcdn.com/mub_audio/6e6e79ef-a732-49d9-8317-4ba97c05a352.mp4

  


  The input file has a pause after every sentence. But in output, that pause duration doesn't have any background music.
What can be the reason ? what is the solution for it ?

  


• avformat/pp_bnk : treat music files as stereo

  13 novembre 2020, par Zane van Iperen

  avformat/pp_bnk : treat music files as stereo
  These files are technically a series of planar mono tracks.
  
  If the "music" flag is set, merge the packets from the two
  
  mono tracks, essentially replicating :
    [0:a:0][0:a:1]join=inputs=2:channel_layout=stereo[a]
