Re: [FFmpeg-devel] [RFC] Proposal for improved remap filter
I am sure there are multiple ways to achieve this. My current idea is to teach/enhance swscale to perform the basic logic for it. In that sort of design it would be able to reuse most of the existing, highly optimized filtering functions - as well as all of its to, and from, planar format conversion logic. But I am also open to pursing other ideas if people think that would be better than an swscale-based design.

[FFmpeg-devel] [RFC] Proposal for improved remap filter
The general feature provided by the remap filter is important in a number of use cases. Lens distortion/correction is one that has been discussed previously. But it is also a key feature in processing video material intended for Virtual Reality and 360 degree playback. These workflows employ non-linear reprojections of the frame in order to deliver video that can be played back by VR-based (head mounted display) players. The current implementation of the remap filter isn't well suited for this task primarily because it is missing high-quality filtering logic similar to what is available in swscale. I would like to propose that this be addressed, and would like to either join or lead an effort to do so.
