 This is a feature request to add and enable Vulkan-based deinterlacing
 filters in ffmpeg.

 Some hardware-accelerated encoder implementations and their wrappers, such
 as NVENC on Turing and newer generation GPUs only support progressive
 encoding, which *will* implicitly break encoding workflows with *some*
 sources when a Vulkan-based filter pipeline is in use without a
 corresponding deinterlacer. Auto-inserting the {{{yadif}}} deinterlacer as
 a work-around to this could be sub-optimal (for performance reasons).

 The lack of a Vulkan-based deinterlacer would also break such Vulkan-based
 video encoding scenarios (when implemented) on such hardware.
