Which flutter_ffmpeg package do you use? Are you aware that x265 is only available in GPL licensed flutter_ffmpeg packages?

chinu999 commented 4 years ago

I am using the least flutter ffmpeg plugin (flutter_ffmpeg: ^0.2.10). And in flutter documentation it says it is using:- License LGPL 3.0 (LICENSE) GPL 3.0 (LICENSE.GPLv3)

There are 8 different packages coming with flutter_ffmpeg. You're using the default one. Can you install one of the GPL licensed packages? 1. Features section in README lists them and 2.1 Packages section explains how you can install a package.
