 Summary of the bug:
 How to reproduce:
 I have used both gyan.dev download of ffmpeg.exe and btbn download.
 btbn gives an error/warning "not enough transformations found" in the
 vidstabtransform step and produce an output file without stabilization.
 The exact same command works in the gyan.dev build with an stabilized
 output file.
 Names of downloads:
 btbn: ffmpeg-master-latest-win64-gpl.zip(2023-01-26)
 gyan.dev: ffmpeg-git-full.7z (2023-01-18)

 I believe it is file independ, input is from a GoPro 9.

 Commands:
 1) ffmpeg -i joined2.mp4 -vf
 vidstabdetect=shakiness=10:accuracy=15:mincontrast=0.200:stepsize=6:show=0:result=data.trf:tripod=0:result=data.trf
 -f null -
 2) ffmpeg -i joined2.mp4 -vf
 vidstabtransform=smoothing=25:crop=black:zoom=0:optzoom=0:interpol='bicubic':input=data.trf:tripod=0
 -c:v libx264 -crf 26 -r 25 -preset fast -pix_fmt yuv420p -y "deshaked.mp4"

 Error: vidstab
