#### libmpv (video playback)
Deep Ocean plays video with libmpv (lib/<abi>/libmpv.so), a shared library the app loads at run time.
It is the "default" build of media-kit/libmpv-android-video-build v1.1.7, which is built WITHOUT any
GPL-only code (mpv -Dgpl=false, FFmpeg --disable-gpl --disable-nonfree --enable-version3). It contains:
