mpv is free and open-source media player software based on MPlayer, mplayer2 and FFmpeg.

[7] It is cross-platform, running on ARM, MIPS, PowerPC, RISC-V, s390x, x86/IA-32, x86-64, and some other by 3rd party.

[8] The motive for the fork was to encourage developer activity by removing unmaintainable code and dropping support for very old systems.

[9] Since June 2015, the project's source code is in the process of being relicensed from GNU General Public License version 2 (GPLv2) or later to GNU Lesser General Public License version 2.1 (LGPLv2.1) or later to allow using mpv as a library in more applications.

This was intended to make interaction easier for new users and to enable precise and direct seeking.
