Image overlay on video using ffmpeg android

I am trying to add image overlay on video using ffmpeg library but didn't succeed.

I tried sample using ffmpeg , https://drive.google.com/file/d/0B2aT0QoEmtuaN0VJZ2Z4ODY3T2s/view

and referred this link as well to overlay image on video, http://ksloan.net/watermarking-videos-from-the-command-line-using-ffmpeg-filters/#comment-9793 but getting error.

Below is my logcat error for reference:

You can use an ffmpeg Android wrapper and the regular ffmpeg command line syntax, which is very well supported and documented, to achieve this - bearing in mind that video processing on a mobile device is a heavy CPU user so may be slower than you would like and may also impact battery usage.

The following is a well supported ffmpeg wrapper:

You can add the image with ffmpeg using a command like this:

ffmpeg -i inputVideo.mp4 -i yourImage.png -filter_complex "overlay=5:5" -codec:a copy outputVideo.mp4

See this answer for more examples of placing the image - i.e. top left, bottom right etc: https://stackoverflow.com/a/10920872/334402
