[FFmpeg-user] Noise generator for 360° video

[Michael Koch]

Does anybody have an idea how to make a noise generator for 360° video? 
I mean noise (clouds, waves) that looks similar in all directions of the 
sphere. If I use the new "perlin" source for making an equirectangular 
video, there are two problems:
1. The left edge doesn't fit to the right edge.
2. There are singularities at the poles.
