Hi all I just installed ffmpeg and I'm quite new to it. managed to combine/merge audio and video file, but now I want to combine 2 audio files and one video into one output file. audio files are: .wav video file is: .flv output is: .flv

currently i have this code, what should I add to it:

system("$ffmpegpath -i audio1.wav -i audio2.wav -i video1.flv -y output.flv");

thank you!

  • hi, to be honest this is a pretty old issue and we didn't get any help. we managed to make it work somehow, but surely not with 2 audio files combined. 1 video + 1 audio. I'll try to get a hold of the files and get back to you. – bboy Jul 09 '14 at 08:11
  • Okay Thanks.. I am trying it more if I am able to get the solution I will share my answer. – Ahmad Arslan Jul 09 '14 at 09:13

I think you have to use the option -map. Read this link, How to encode multi audio streams with different options at the same time with ffmpeg

Example:

ffmpeg -i merged-vobs.mpeg -map 0:0 -s 640x368 -f ogg -vcodec libtheora -r 25 -b:v 1200k -metadata:s:v:0 title= "Video Title" -acodec libvorbis -ar 48000 -map 0:1 -ac:a:0 6 -b:a:0 192k -metadata:s:a:0 title="Track1 Title" -map 0:4 -ac:a:1 2 -b:a:1 96k -metadata:s:a:1 title="Track2 Title" -async 1 -pass 2 -passlogfile "outputlog" "output.ogv"

found the project and this is my solution to it:

<?php
    $ffmpegpath = "ffmpeg.exe"; /////ffmpeg.exe path, I have it in the same folder
    $videoFile = "videoplayback.flv";
    $audioFile = "comment.wav";
    $targetVideo = "output.flv";

    //
    system("$ffmpegpath -i $audioFile -i $videoFile -y $targetVideo");
?>

let me know if it helps!
