-- This script cycles between deinterlacing, pullup (inverse
|
|
-- telecine), and both filters off. It uses the "deinterlace" property
|
|
-- so that a hardware deinterlacer will be used if available.
|
|
--
|
|
-- It overrides the default deinterlace toggle keybinding "D"
|
|
-- (shift+d), so that rather than merely cycling the "deinterlace" property
|
|
-- between on and off, it adds a "pullup" step to the cycle.
|
|
--
|
|
-- It provides OSD feedback as to the actual state of the two filters
|
|
-- after each cycle step/keypress.
|
|
--
|
|
-- Note: if hardware decoding is enabled, pullup filter will likely
|
|
-- fail to insert.
|
|
--
|
|
-- TODO: It might make sense to use hardware assisted vdpaupp=pullup,
|
|
-- if available, but I don't have hardware to test it. Patch welcome.
