Using NodeJS to combine a png and mp3 to make a mp4-CodePudding

So I am trying to combine a mp3 file and png with nodejs to make a mp4 file. I tried searching for modules and such, but cannot find one.

CodePudding user response：

I do recommend using ffmpeg, by using this npm package https://www.npmjs.com/package/ffmpeg.

I think this answer would help you creating mp4 from png images and audio How to create a video from images with FFmpeg?

CodePudding user response：

You can use the fluent-ffmpeg package:

For example of how ot work, here is an example of resizing a mp4:

var ffmpeg  = require( 'fluent-ffmpeg' );
ffmpeg( path.join( toDirectory, newVideo._id   '.orig.mp4' ) )
      .size( '1024x576' )
      .fps( 25 )
      .videoCodec( 'libx264' )
      .videoBitrate( '1024k' )
      .output( path.join( toDirectory, newVideo._id   '.mp4' ) )
      .audioBitrate( '92k' )
      .audioFrequency( 48000 )
      .audioChannels( 2 )
      .run();

For creating a mp4 from image with sound (Not tested):

var ffmpeg  = require( 'fluent-ffmpeg' );

let newMp4 = ffmpeg();
newMp4
    .input("./test.png")
    .input("./another.png")
    .addInput('/path/to/audio.file')
    .save("./test.mp4")
    .outputFPS(1) // Control FPS
    .frames(2) // Control frame number
    .on('end', () => {
        console.log("done");
    });
