In vidstabtransform filter the zoomspeed option does not work

Reported by: Tom Steck Owned by:

Summary of the bug: I try to stabilize various videos and I am checking different vidstabtransform options. I can confirm that optzoom=2 option works (dynamic zoom) but the zoomspeed option doesn't.

First I stabilized video with zoomspeed = 0.01 (min value), then I stabilized the same video with zoomspeed = 5 (max value). Finally I compared two videos with kdenlive "difference" transition and there was no difference (black screen). Therefore, my conclusion is that zoomspeed option doesn't work.

How to reproduce:

% ffmpeg -i input -vf vidstabtransform=input=input.xml:interpol=bicubic:smoothing=100:optzoom=2:zoomspeed=5 -vcodec libx264 -level 4.2 -preset veryslow -tune film -crf 23 -an output
ffmpeg version N-77953-gcc83177
built with gcc 5.2.0 (GCC)

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

I checked again and it works!
My mistake I guess.
