Weave Deinterlacing

Weave deinterlacing is the act of interleaving the lines of two temporally adjacent fields to form a frame for display. To disable deinterlacing for progressive streams, simply specify current as NVMEDIA_PICTURE_STRUCTURE_FRAME; no deinterlacing will be applied. Weave deinterlacing for interlaced streams is identical to disabling deinterlacing, as describe immediately above, because each ref NvMediaVideoSurface already contains an entire frame's worth (i.e., two fields) of picture data. Weave deinterlacing produces one output frame for each input frame. The application should make one NvMediaVideoMixerRenderSurface call per pair of decoded fields, or per decoded frame. Weave deinterlacing requires no entries in the past/future lists.
