I think one way to handle screensaver blocking could be to at start run
an external command that manages the blocking, and possibly kill the
external command on exit or run other command then.

The XDG standard have one command: xdg-screensaver suspend windowid that
blocks sceensaver and power management as long as windowid exists.
There is an other command to resume it on same windowid if windowid is
not going away.

It should be possible to write special scripts where the xdg commands do
not exist.

This way mplayer do not need to run a heartbeat command or do some other
operations now and then to simulate activity. Instead just one command
at start and possible one at exit.
