zoompan filter outputs shaky vidoe

Description

Adding a zoompan filter to an image with no panning works smoothly, however when panning the zoom to the center of the image, the result is a video with a shaky image.
I have used the same filter example as shown in the zoompan filter documentation.

This is the command line:

ffmpeg -y \
-i img.jpg \
-filter_complex "zoompan=z='min(zoom+0.0015,1.5)':d=125:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)'" \
-vcodec libx264 -pix_fmt yuv420p -r 25 -t 5 out.mp4

Below is the console output. I have also attached the full console output, input image and the output video.

Isn't this a duplicate of ticket #4298?
Please always test current FFmpeg git head before reporting an issue and please do not attach output files, they generally create confusion.

comment:2 Changed 2 years ago by jammy

I have tested the zoompan feature on git head with the same results.
Yes it seems as a duplicate of ticket #4298.
