[FFmpeg-devel] [GSOC] [PATCH] avfilter: add panorama filter

[Eugene Lyapustin]

Hello,

This patch is a qualification task on 360 video filter.
I took a filter originally written by Paul B Mahol, and which was modified last year by another student. The filter had a lot of hardcoded conversions between formats, and it would be a pain to extend it with new ones. So I unified the remap calculation procedure. Now all formats only need functions to convert format coordinates to cartesian coordinates and vice versa. 

Regards,
Eugene Lyapustin
