-- Simple script for configurable TV out activation and/or deactivation on mpv playback
|
|
--
|
|
-- Intended to activate TV on mpv startup and deactivate TV on mpv close if TV is connected.
|
|
-- The script executes fully configurable shell sequences (e.g. xrandr on linux)
|
|
-- Can also be used for activating ambient lighting while watching etc ...
|
|
--
|
|
-- Note: There are implicit security issues due to a nature of direct execution
|
|
-- of command line tools without any sanitization ...
|
|
--
|
|
-- TV configurable options:
|
|
-- test ... check if TV is connected (result is non empty, exitcode 0)
|
|
-- on ... executed once on mpv player startup (TV ON)
|
|
-- off ... executed once on mpv player shutdown (TV OFF)
|
|
--
|
|
-- Note: xrandr seems to have problem turning off and on devices on single execution.
|
|
-- Therefore it is wise to split execution to multiple commands, for example:
|
|
-- problem : xrandr --output LVDS1 --off --output TV1 --auto
|
|
-- works ok: xrandr --output LVDS1 --off && xrandr --output TV1 --auto
|
|
--
|
|
-- To customize configuration place tv.conf into ~/.config/mpv/lua-settings/ and edit
|
|
--
|
|
-- Place script into ~/.config/mpv/scripts/ for autoload
|
