[FFmpeg-user] vidstabtransform separate x/y maxshift

[Vukovics Mihaly]

Hello Guys,

I am using vidstabdetect/transform a lot for stabilizing head mount 
camera. When you turn your head the filter tries to correct it, which is 
not so good in this case.
It would be nice to be able to control the maxshift vaule by x and y 
axis separately, thus x/y correction can be set differently or 
completely disable (set to 0).

BR,
Mihaly
