Comment (by Michael Koch):

 Replying to [comment:8 Saul Baker]:

 > I genuinely feel that the previous behaviour was more applicable to use
 cases of the filter, certainly in that repo example and Michael's book
 code it's the most direct and standardised expression of how to manipulate
 the filter - incremental stateful adjustment simply seems like the wrong

 If it doesn't work any more in FFmpeg, you can do the same thing with
 DaVinci Resolve and the "KartaVR" plugin. You can define keyframes and set
 the rotation angles, and it does also interpolate the angles between the
 keyframes. I don't know if it works with the free version.

 By the way, my approach for spherical stabilization with FFmpeg is now
 also broken. But that doesn't matter, because the spherical stabilizer in
 DaVinci Resolve is much better.
