-- 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.
