[FFmpeg-devel] [PATCH 0/2] Interpolation filter using nvidia OFFRUC Library

This filter implements frame rate down/upsampling using nvidia's
Optical Flow FRUC (Frame Rate Up Conversion) library. It's neat because
you get realtime interpolation with a decent level of quality. It's
impractical because of licensing.

I have no actual intention to merge this, as it doesn't even meet our
bar for a nonfree filter, and given the EULA restrictions with the SDK,
anyone who would want to use it can easily cherry-pick it into the
build they have to anyway. But I figured I'd send it to list as a way
of announcing that it exists.

How nice would it be if nvidia had sane licensing on this stuff?

I'll keep a branch at: https://github.com/philipl/FFmpeg/tree/fruc-me
