Merging 2 videos in android

I want to merge or mix 2 videos in android app. I tried using mp4parser but it is appending the video and I want to mix the frames. I want video to be mixed by 10 seconds from one video and 10 seconds from 2nd video.

Any piece of code would be appreciated.

You can use the mp4parser library to append videos. The problem is the limited documentation.

here is the link of mp4parser lib https://code.google.com/archive/p/mp4parser/

or

You can use ffmpeg which is providing amazing features to the users to compress, split, merge and all kind of video/ audio editing/compressing/trancoding,etc. Version 1.1 (ffmpeg fire flower) onwards concat demuxer has been added to it, This is working fine in my android application.
