I'm developing an Android App that records screen video and audio.
I recorded these 2 files : mp3 audio file and mp4 video file(no sound).
Now I want to mix them and create a new mp4 video file(with sound).
From Android 4.3, Google suggests using the MediaMuxer class to mix stream audio and video. I have tried many times without success.
Any solution to resolve my issue with MediaMuxer API from Google?
Any help will be greatly appreciated.
