See https://github.com/mpv-player/mpv/issues/7983

mpv doesn't call KDSKBMODE ioctl, so input remains under VT control but
not visible due to video showing on top. One can still control mpv via
stdin(4) using a keyboard but keybindings would be limited by termios(4).
For example, Ctrl+S would pause playback after a few seconds instead of
taking a screenshot.

SDL2 probably has a bug. SDL1 uses vgl(3) instead of KDSKBMODE directly.
