You can use jcodec SequenceEncoder to convert sequence of images to MP4 file.

Sample code :

import org.jcodec.api.awt.SequenceEncoder;
...
SequenceEncoder enc = new SequenceEncoder(new File("filename"));
// GOP size will be supported in 0.2
// enc.getEncoder().setKeyInterval(25);
for(...) {
    BufferedImage image = ... // Obtain an image to encode
    enc.encodeImage(image);
}
enc.finish();

It's a java library so it's easy to import it into Android project, you don't have to use NDK unlike ffmpeg.

Refer http://jcodec.org/ for sample code & downloads.
