• Discord.py music bot doesn't play next song in queue

  10 mai 2019, par Lewis H

  This is my code for the bot I’m trying to create, it plays the music fine.

  ytdl_options = {
  
      'format': 'bestaudio/best',
  
      'restrictfilenames': True,
  
      'noplaylist': True,
  
      'nocheckcertificate': True,
  
      'quiet':True,
  
      'ignoreerrors': False,
  
      'logtostderr': False,
  
      'no_warnings': True,
  
      'default_search': 'auto',
  
      'source_address': '0.0.0.0' # using ipv4 since ipv6 addresses causes issues sometimes
  
      }
  
  
  
  
  
          # ffmpeg options
  
  ffmpeg_options= {
  
      'options': '-vn'
  
      }
  
  
  
  
  
  
  
  @bot.command()
  
  async def play(ctx, url:str = None): 
  
      queue = {} 
  
  
  
      channel = ctx.author.voice.channel    
  
      if ctx.voice_client is not None:  
  
          await ctx.voice_client.move_to(channel)
  
      elif ctx.author.voice and ctx.author.voice.channel:       
  
          await channel.connect()
  
  
  
      if not url:
  
          await ctx.send("Try adding a URL. e.g. !play https://youtube.com/watch?v=XXXXXXXXX")
  
  
  
      if ctx.voice_client is not None:
  
          vc = ctx.voice_client #vc = voice client, retrieving it
  
          ytdl = youtube_dl.YoutubeDL(ytdl_options)
  
  
  
  
  
          loop = asyncio.get_event_loop()
  
          data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url))
  
  
  
          if 'entries' in data:
  
              data = data['entries'][0] 
  
          svr_id = ctx.guild.id
  
          if svr_id in queue:
  
              queue[svr_id].append(data)
  
  
  
          else:
  
              queue[svr_id] = [data]
  
          await ctx.send(data.get('title') + " added to queue")
  
  
  
          source = ytdl.prepare_filename(queue[svr_id][0])
  
          def pop_queue():
  
              if queue[svr_id] != []:
  
                  queue[svr_id].pop(0)
  
                  data = queue[svr_id][0]
  
              else:
  
                  vc.stop()
  
  
  
          if not vc.is_playing():
  
              vc.play(discord.FFmpegPCMAudio(source, **ffmpeg_options), after=lambda: pop_queue())

  The next song downloads and queues it fine, but once the first song finishes, it doesn’t play the next one. I can’t figure out how to make it play after the first song has commenced. I have the after= set to remove the top item of the queue, but how do I get it to play again ? Thanks

• Using ffmpeg to stream to Facebook Live Video : with default webcam and mic

  16 septembre 2017, par suraj kiran

  i tried commands like this
  ffmpeg -i /dev/video0 -vf scale=320:240 -t 5400 -c:a copy -ac 1 -ar 44100 -b:a 128k -c:v libx264 -pix_fmt yuv420p -r 30 -g 60 -vb 2048k -minrate 2000k -maxrate 4000k -bufsize 4096k -f pulse flv "rtmp://live-api-a.facebook.com:80/rtmp/279340769232610?ds=1&s_l=1&a=AThKJag2wqGSJkDI"
  but all those resulted as streaming in ffmpeg but no video appears on facebbok.
  can anyone provide correct command for ffmpeg to stream with my webcam and mic. i prefer low quality video stream(about 360p) due to my poor network
