Adding watermark bitmap over video in android: 4.3's MediaMuxer or ffmpeg

Question

Here is my scenario:

• Download an avi movie from the web
• Open a bitmap resource
• Overlay this bitmap at the bottom of the movie on all frames

Answer 1

This is what worked for me:

ffmpeg -i input.avi -i logo.png -filter_complex 'overlay=10:main_h-overlay_h-10' -strict -2 output.avi

ffmpeg recommended the usage -strict -2 inorder to allow the usage of experimental codecs. without the inclusion, the accepted answer above fails to work.
