title: Combine an image into audio file and make a video file in android programmatically
body: <p>I gone through the tutorial of ffmpeg library to combine the image into audio file.</p>
  
  <p>This is looking very complex and getting error with environment value is null.</p>
  
  <p>I researched a lot but didn't find any solution.</p>
  
  <p>Is there any way in Android to merge an image and an audio file to make a video?</p>
