I did object and have NAK'd the patch currently.
Make the submitter submit a new version themselves and I'll approve it.
There was a new version submitted already, I just replied to the wrong one.

Will apply with some minor changes (some unused variables are still

It would be nice, yes, but I'm not sure there is actually that much need with
the current setup. The use-cases for the two as currently written don't really
overlap - CUDA is useful in the cases you describe with (possibly multiple)
high-power GPUs trying to squeeze as much performance as poss

The problem is not with the thumbnail filter at all. The problem is doing the
transfers from vidmem to sysmem or vice-versa. You will observe if we use a

I believe there were concerns on pushing the CUDA thumbnail filter and that is
possible to get similar performance using the normal thumbnail filter. The CUDA
thumbnail filter is useful for generating thumbnails on the hwaccel cuvid
pipeline, as it can directly operate on the video memory and gi

We have av_pixelutils_sad_fn which does SAD and has SIMD, there's no point
in reinventing the wheel.
I also don't see why this needs to be implemented with CUDA. You're not
even doing the SAD in CUDA. I bet it'll be just as fast if not faster in C
(unless you cheat somehow).
The point is to do

Without having done a full review on the code yet:
A new filter needs a libavfilter version bump(not 100%
