• how to fade in and out background music when speech play and fade out audio at the end and mix them together using ffmpeg

  3 avril 2019, par Harshil Dholakiya

  I am using below command in my project to mix background music with my speech audio and background music slow down volume level when speech play :

  ffmpeg -y -i speech.mp3 -stream_loop -1 -i music.mp3 -filter_complex "[0:a]asplit=2[sc][mix];[1:a][sc]sidechaincompress=threshold=0.01:ratio=5[bg];[mix][bg]amix=inputs=2:duration=first:dropout_transition=0[final]" -map [final] finalAudio.mp3

  i want to add this two filter to audio :

  1) Fade-in effect to background music for 1.5 sec when speech arrive and fade-out effect when speech is finish for 1.5 sec. speech.mp3 has more than one speech and silence in between speech.

  2) Fade out effect at the end of audio for 1.5 sec.

  can anyone help me to achieve both of above filter using ffmpeg with my above command ?

• My own music bot randomly stops when playing a song, no errors, just like the song has ended

  18 avril 2019, par Stasio

  I made a discord music bot but there is one problem :
  When i play something it works perfectly for a moment but then sometimes music ends in the middle of the song just like the song has ended.
  When there are some songs in queue and this bug happens the bot starts playing another song from the queue. Im using ffmpeg, ytdl-core, simple-youtube-api,
  opusscript. What do u guys think about it ? I don’t think that this problem is caused by my code cuz this error happens randomly, sometimes 3 songs in a row are played normaly and sometimes it crashes in the middle of the 1 song, so he starts playing the next song in queue.

  const arg = msg.content.split(' ');
  
  const searchString = arg.slice(1).join(' ');
  
  const url = arg[1] ? arg[1].replace(/<(.+)>/g, '$1') : '';
  
  const serverQueue = queue.get(msg.guild.id);
  
  
  
  let command = msg.content.toLowerCase().split(' ')[0];
  
  command = command.slice(PREFIX.length)
  
  
  
  if (command === 'play' || command === 'p') {
  
  msg.delete()
  
  const voiceChannel = msg.member.voiceChannel;
  
  let emoji = msg.guild.emojis.find(x => x.name === "2Head")
  
      if (!voiceChannel) return msg.channel.send('Nie jesteś nawet na kanale głosowym zjebie ' + emoji);
  
      const permissions = voiceChannel.permissionsFor(msg.client.user);
  
      if (!permissions.has('CONNECT')) {
  
          return msg.channel.send('Nie mam permisji zeby sie polaczyc ;/');
  
      }
  
      if (!permissions.has('SPEAK')) {
  
          return msg.channel.send('Nie moge mowic odmutujcie mnie : )');
  
      }

          const playlist = await youtube.getPlaylist(url);
  
          const videos = await playlist.getVideos();
  
          for (const video of Object.values(videos)) {
  
              const video2 = await youtube.getVideoByID(video.id); 
  
              await handleVideo(video2, msg, voiceChannel, true); 
  
          }
  
          return msg.channel.send(`✅ Playlist: **${playlist.title}** has been added to the queue!`);
  
      } else {

          } catch (error) {
  
              try {
  
                  var videos = await youtube.searchVideos(searchString, 1);
  
                  var video = await youtube.getVideoByID(videos[0].id);

        console.error(err);
  
        let emoji = msg.guild.emojis.find(x => x.name === "autism")
