In vidstabdetect filter the shakiness and the stepsize options do not work

[Tom Steck]

Summary of the bug: I try to stabilize various videos and I am checking different vidstabdetect options.

First I stabilized video with shakiness=1 and stepsize=1 (min values), then I stabilized the same video with shakiness=10 and stepsize=6 (max value). Finally I compared two videos with kdenlive "difference" transition and there was no difference (black screen). Therefore, my conclusion is that shakiness and stepsize options do not work.

How to reproduce:

% ffmpeg -i input -vf vidstabdetect=shakiness=1:stepsize=1:result=video.xml -f null out.null
ffmpeg version N-77953-gcc83177
built with gcc 5.2.0 (GCC)
ffmpeg-20160119-git-cc83177-win64-static.7z

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

[Carl Eugen Hoyos]

Please test current FFmpeg git head and please provide the command line that allows to reproduce the issue together with the complete, uncut console output to make this a valid ticket.

I opened ​​http://ffmpeg.zeranoe.com/builds/ and downloaded ffmpeg-20160219-git-98a0053-win64-static.7z - git-98a0053 (2016-02-19). I don't know how to compile FFmpeg on my Windows 10.

First I stabilized the video with the shakiness=1
I am using Python 2.7 to run first psutil.Popen(step1), where step1 is a list:
['ffmpeg', '-i', 'Young16sec.mp4', '-vf', 'vidstabdetect=shakiness=1:stepsize=5:result=Young16sec.crf25.xml', '-f', 'null', 'out.null']

and for psutil.Popen(step2) step2:
['ffmpeg', '-y', '-i', 'Young16sec.mp4', '-vf', 'vidstabtransform=input=Young16sec.crf25.xml:interpol=bicubic:smoothing=100:optzoom=2:zoomspeed=0.25:maxshift=10:zoom=0,unsharp=5:5:0:5:5:0', '-vcodec', 'libx264', '-level', '4.2', '-preset', 'veryslow', '-tune', 'film', '-crf', '25', '-an', 'Young16sec.crf25.mp4']

For the second stabilization I set shakiness=10
Step 1:
['ffmpeg', '-i', 'Young16sec.mp4', '-vf', 'vidstabdetect=shakiness=10:stepsize=5:result=Young16sec.crf25.xml', '-f', 'null', 'out.null']

Step 2:
['ffmpeg', '-y', '-i', 'Young16sec.mp4', '-vf', 'vidstabtransform=input=Young16sec.crf25.xml:interpol=bicubic:smoothing=100:optzoom=2:zoomspeed=0.25:maxshift=10:zoom=0,unsharp=5:5:0:5:5:0', '-vcodec', 'libx264', '-level', '4.2', '-preset', 'veryslow', '-tune', 'film', '-crf', '25', '-an', 'Young16sec.crf25.mp4']

Below is the entire console output from stabilizing the same video file using two different shakiness settings.
