2018-11-02libavfilter/vf_yadif: Make frame management logic and options shareablePhilip Langdale
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 introducing a function pointer for the filter() function so it can be specified for the specific filter.
