From the FFmpeg docs on images:

The following example shows how to use ffmpeg for creating a video from the images in the file sequence ‘img-001.jpeg’, ‘img-002.jpeg’, ..., assuming an input frame rate of 10 frames per second:

ffmpeg -i 'img-%03d.jpeg' -r 10 out.mkv

To actually run it from Android, look at the documentation for Runtime.exec().
