title: How to run FFMPEG commands from android
body: <p>I am new with ffmpeg, so what I want is to run the ffmpeg commands through my native C file.I had seen some example which said to pass the command in the <code>main()</code> function of <code>ffmpeg.c</code> file. I am doing the same but I am getting <code>undefined reference to 'main'</code>. How can we run basic ffmpeg commands in android?</p>
