• Streaming ffmpeg output directly to dispatcher

  4 novembre 2020, par PP_Hyperion

  I'm trying to play music with my discord bot and I want to use ffmpeg to specify the start of the music, which works perfectly fine, but I can only download the music with ffmpeg and then play it. I want ffmpeg to process it and then also stream it to play the music.

  



  Here is the code I use to download and then play the music :

  



  message.member.voiceChannel.join().then((con, err) => {
    ytPlay.search_video(op, (id) => {
        let stream = ytdl("https://www.youtube.com/watch?v=" + id, {
            filter: "audioonly"
        });
        let audio = fs.createWriteStream('opStream.divx');

        proc = new ffmpeg({
            source: stream
        })
        proc.withAudioCodec('libmp3lame')
            .toFormat('mp3')
            .seekInput(35)
            .output(audio)
            .run();
        proc.on('end', function() {
            let input = fs.createReadStream('opStream.divx');
            console.log('finished');
            guild.queue.push(id);
            guild.isPlaying = true;
            guild.dispatcher = con.playStream(input);
        });
    });
})


  



  Is it possible to do what I want and if yes how ?

  


• ffmpeg - video with looped audio

  5 septembre 2013, par mete7

  I have image 14 image files(jpg) and 1 audio file(mp3). I generated a video from images with FFMPEG using that code :

  ffmpeg -r 1/3 -i img%d.jpg nomusic.avi

  The video is 42 seconds (14*3=42). And than i want to add music so i used this code :

  ffmpeg -r 1/3 -i img%d.jpg -i loop1.mp3 -y withmusic.avi

  The problem is my music file is 10 second longer so the music goes in the 10 second of video. I want to make the music looped during the video.

  NOTE : I use Win7

• Adding background audio in FFMPEG, but quieting it if there is sound in another channel

  9 septembre 2021, par Connor Bell

  I'm appending several videos together with FFMPEG. Some of these videos have accompanying audio, and some do not.

  


  I'd like to add music in the background, and have found out how to do so from here. However, I'd like the background music to be (let's say 80%) quieter if there is already audio in that video. Note that all videos have a null audio track, so just checking for the existence of an audio track isn't sufficient.

  


  My current process is :

  


  

  • Take source videos, add a null audio source and upscale (The null audio source is required for ffmpeg-concat to work due to a bug, I think)

  


  • Combine the videos using ffmpeg-concat

  


  


  Preferably, adding the background music should be the third step, as splitting the background music prior to combining the videos sounds more complex, but I may be wrong.
