How to combine multiple mp4 files into one using android's MediaMuxer api?

Issue

I want to combine multiple mp4 fiels into one video. There is an MediaMuxer class in Android framework and it seems that can do that. But I didn't find any clear sample for that. Is it possible to combine multiple video files(containing both video and audio) using MediaMuxer? If so, Could you please provide me a clear sample? Thanks a lot.

Solution

According to the docs MediaMuxer supports multiple video/audio tracks just for mp4 format and only for api +26 and not earlier versions. Also Some good samples can be found here.
