Description (last modified by )
When the input of
gblur filter is resized in time, the
gblur would keep blurring just the original area (size).
In this example input is resized from 100x100 to 200x200 within 5 frames, however only 100x100 area is blurred in every frame.
Also tried with
gblur doesnt seem to have the option.
How to reproduce:
% ffmpeg -f lavfi -i color=size=200x200:rate=5:d=1 -i lines.png -filter_complex "setpts=N/5/TB,fps=5,tpad=stop_mode=clone:stop_duration=1,scale=iw+n*20:-1:eval=frame,gblur=10,overlay" -y out%%d.png
