There's a very easy solution for this, There's a precompiled library for android, as below https://github.com/WritingMinds/ffmpeg-android-java Simply include this as a gradle project in your code and add few methods as per their documentation and you are done with FFMPEG commands in android. This library is not very updated and have some missing features but still its good to use for many simple tasks.
