-- CYCLE-VIDEO-ROTATE.LUA
-- Version: 1.0
-- Author: VideoPlayerCode
-- URL: https://github.com/VideoPlayerCode/mpv-tools
--
-- Description:
--
-- Allows you to perform video rotation which perfectly
-- cycles through all 360 degrees without any glitches.
--
-- -----------------------------------------------------------
function cycle_video_rotate(amt)
-- Ensure that amount is a base 10 integer.
amt = tonumber(amt, 10)
if amt == nil then
mp.osd_message("Rotate: Invalid rotation amount")
return nil -- abort
end
-- Calculate what the next rotation value should be,
-- and wrap value to correct range (0 (aka 360) to 359).
local newrotate = mp.get_property_number("video-rotate")
newrotate = (newrotate + amt) % 360
-- Change rotation and tell the user.
mp.set_property_number("video-rotate", newrotate)
mp.osd_message("Rotate: " .. newrotate)
end
-- Bind this via input.conf. Example:
-- Alt+LEFT script-message Cycle_Video_Rotate -90
-- Alt+RIGHT script-message Cycle_Video_Rotate 90
mp.register_script_message("cycle_video_rotate", cycle_video_rotate)
