I can't find an example how to make the Xmap and Ymap files with ffmpeg.
In the wiki the files are made with a C program which is difficult to
This example is from the documentation of the displace filter:
ffmpeg -i INPUT -f lavfi -i nullsrc=s=hd720,lutrgb=128:128:128 -f lavfi
-lavfi 'displace' OUTPUT
However for the remap filter we need only one 16-bit value per pixel.
Not three 8-bit RGB values. How can this be created with ffmpeg?
