ffmpeg两个音频，一个视频输出

Question

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!

Answer 1

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!
