From jagadish answer, i tried the command like this, this is worked for me.

-y -i /storage/emulated/0/images.jpg -i /storage/emulated/0/rec.wav -acodec aac -vcodec mpeg4 -s 480*320 -f mp4 -r 2 /storage/emulated/0/result.mp4"

Answer 2

I found the solution after applied lot of tricks.

public void myFunction(ShellCallback sc, String imgPath, String audioPath, String outPath) throws IOException, InterruptedException
    {

        Log.e("MyFunction","audioPath"+audioPath);
        Log.e("MyFunction","imagePath"+imgPath);
        ArrayList<String> cmd = new ArrayList<String>();

        cmd = new ArrayList<String>();

        cmd.add(ffmpegBin);
        cmd.add("-y");
        cmd.add("-loop");
        cmd.add("1");
        cmd.add("-r");
        cmd.add("1");
        cmd.add("-i");
        cmd.add(new File(imgPath).getCanonicalPath());
        cmd.add("-i");
        cmd.add(new File(audioPath).getCanonicalPath());
        cmd.add("-acodec");
        cmd.add("aac");
        cmd.add("-vcodec");
        cmd.add("mpeg4");
        cmd.add("-s");
        cmd.add("480x320");
        cmd.add("-strict");
        cmd.add("experimental");
        cmd.add("-b:a");
        cmd.add("32k");
        cmd.add("-shortest");
        cmd.add("-f");
        cmd.add("mp4");
        cmd.add("-r");
        cmd.add("2");
        File fileOut = new File(outPath);
        cmd.add(fileOut.getCanonicalPath());

        execFFMPEG(cmd, sc);
    }

I hope this may help others.Thanks!

Try with the below command it should work with multiple images Library - https://github.com/WritingMinds/ffmpeg-android-java

Here test$04d.png refers to series of images like test0001.png, test0002.png etc.. make sure that you have the same name image conventions for your images names

ffmpeg -r 1/5 -i /storage/emulated/0/Pictures/Screenshots/test%04d.png -c:v libx264 -vf fps=20 -pix_fmt yuv420p /storage/emulated/0/Movies/out.mp4

With Music file

ffmpeg -r 1/5 -i /storage/emulated/0/Pictures/Screenshots/test%04d.png -i /storage/emulated/0/Pictures/Screenshots/music.mp3 -c:v libx264 -vf fps=20 -pix_fmt yuv420p /storage/emulated/0/Movies/out.mp4

Good luck

   inputCode = new String[]{FileUtils.getFFmpeg(getApplicationContext()),
                "-y", "-r", "15", "-i", ImageListDirectory + "",
                "-i", Environment.getExternalStorageDirectory() + "/" + "MusuicFile.mp3", "-shortest",
                "-c:v", "libx264", "-pix_fmt", "yuv420p", "-c:a", "aac", Outputpath};

you can try this command.
