Media Converter app
Note: the source repo of this app seems to be no longer actively maintained, while at least one newer version was released at Google Play. Looks like the app went closed-source, or the repo has moved without a pointer.
Media Converter is a robust Android application build on top of FFmpeg with clean UI. As it name, user can convert media file to other encoding format easily with preset commands. The app also can be extended, by allowing user to create their own command.
