• FFMPEG background music

  12 avril 2018, par Muhammad Sanaullah

  I am having a problem adding background music to concat videos, I read online using amerge and loop function can be possible, but i don’t have idea how i can achive that.

  My ffmpeg command, which is working, join video, add watermark, add intro and outro.

  /usr/bin/ffmpeg -i "/home/main/1515b7e4471944edce419f8e24f5c1a8::13.mp4" -i "/home/demo/intro.mp4" -i "/home/main/2b011d97e633049ec3c4605470cd8306::8.mp4" -i

• Doubts in the development of a music bot for discord, using DSharpPlus and ffmpeg

  21 avril 2018, par Vralago

  I have been making a bot for Discord, and recently I thought about adding the music system. Well I even understand how it works but also have some things that I’m not understanding how I should do it (I’m using the DiscordSharpPlus api), for example putting the music on pause (bearing in mind that ffmpeg continues to read the music).

  So I wanted to know if anyone can explain me or tell me how I should do it or how it works, given that it is my first time using ffmpeg and I do not know all the functions of the program.

  If it is necessary, there is the code where the ffmpeg is and the sending of data to the discord.

  public static async Task AddMusicFromYoutube(VoiceNextConnection vnc, CommandContext ctx, string url)
  
  {
  
      string fileName = "";
  
  
  
      if (url.ToLower().Contains("youtube.com"))
  
      {
  
          fileName = await DownloadFromYouTube(url);
  
          if (fileName == string.Empty) return;
  
  
  
          await ctx.RespondAsync($"Playing for **Youtube** -> `{url}`");
  
          await vnc.SendSpeakingAsync(true);
  
  
  
          var ffmpeg_pro = new ProcessStartInfo
  
          {
  
              FileName = "Libs/ffmpeg",
  
              Arguments = $@"-xerror -i ""{fileName}.mp3"" -ac 2 -f s16le -ar 48000 pipe:1",
  
              RedirectStandardOutput = true,
  
              UseShellExecute = false
  
          };
  
          var ffmpeg = Process.Start(ffmpeg_pro);
  
  
  
          Stream ffout = ffmpeg.StandardOutput.BaseStream;
  
  
  
          using (var ms = new MemoryStream())
  
          {
  
              await ffout.CopyToAsync(ms);
  
              ms.Position = 0;
  
  
  
              var buff = new byte[3840];
  
              var br = 0;
  
              while ((br = ms.Read(buff, 0, buff.Length)) > 0)
  
              {
  
                  if (br < buff.Length)
  
                      for (var i = br; i < buff.Length; i++)
  
                          buff[i] = 0;
  
  
  
                  await vnc.SendAsync(buff, 20); // Send PCM date for discord
  
  
  
                  //tentativa de parar a musica
  
                  if (Program.IsPuased)
  
                  {
  
                      while (Program.IsPuased)
  
                      {
  
                      }
  
                  }
  
              }
  
  
  
              ms.Close();
  
          }
  
          await vnc.SendSpeakingAsync(false);
  
      }
  
      else
  
      {
  
          await ctx.RespondAsync($"{ctx.Member.Mention}, por agora só aceito link's do Youtube!");
  
          return;

• ffmpeg : How to concat audio files and add background music in a single command ?

  1er mai 2018, par harishkumar329

  Need to concat audio files and add background music in a single command.

  Right now I use the following commands to do so,

  To concat :

  ffmpeg -i 1.mp4 -i 2.mp4 -i 3.mp4 -i 4.mp4 -i 5.mp4 -i 6.mp4 -i 7.mp4 -i 8.mp4 -i 9.mp4 -i 10.mp4  -filter_complex '[0:0][1:0]concat=n=10:v=0:a=1[out]'  -map '[out]' -strict -2 -y 10_final.mp4

  To add background music :

  ffmpeg -i 10_final.mp4 -i music.mp4 -filter_complex "[0:a]volume=1dB[a0];[1:a]volume=0.5[a1];[a0][a1]amerge=inputs=2[a]" -map "[a]" -ac 1 -ab 32000 -ar 22050 -strict -2 -y 10_with_music.mp4

  But his process is a quite time-consuming process as every time the file read/write happening to the output.

  Is there a way I can merge these two above commands to a single so that the command should be optimized.
