[FFmpeg-devel] [PATCH 0/3] CUDA implementation of yadif filter v2

This patch series adds a CUDA implementation of yadif so that we have a deinterlacing option when doing full GPU transcode or playback with nvdec and/or nvenc. The nvidia deinterlacer cannot be used with the nvdec decoder because an hwaccel cannot return more than one frame per input packet. (It do

I'm writing a cuda implementation of yadif, and while this obviously has a very different implementation of the actual filtering, all the frame management is unchanged. To avoid duplicating that logic, let's make it shareable. From the perspective of the existing filter, the only real change is in
