-- 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.
