With VDR integration using the xineliboutput plugin the config looks like this for the most common deinterlace. I note that with VDR I had jerkiness and artifacts using this config, but when I switched the "cheap_mode" to =0 oth got much better. You should be able to adapt this config as they are standard parameters.
xineliboutput.Video.Deinterlace = tvtime
xineliboutput.Video.DeinterlaceOptions = method=Linear,cheap_mode=1,pulldown=none,framerate_mode=full,judder_correction=1,use_progressive_frame_flag=1,chroma_filter=0,enabled=1
