dof not working when stitching

[laurenchen0631]

dof algorithm will show an error on video1 on my macbook m1 Ventura.

My python version is 3.11.0, and downgrading 3.9.5 doesn't work as well.

For some input, the dof stitching will create the vertically inverted image.

Have you ever tried calling fillBackground instead of fill_background, maybe this issue will not happen on that case
The root cause might be python stitch library cannot find the common place to stitch after we do background extraction ...

[studentBC]

a quick work around should be unmark line 104 and replace it like
sampleBG = [ frames[i] for i in range(0, frame_count, 10) ]
that should solve your problem and let you focus on developing new features first

[laurenchen0631]

I would just use some workable algorithm when I develop it for now.
Btw, I updated the issue description.

[studentBC]

For your workaround, change line 101 and 104 it shall works well

As for output upside down problem, we will work on it
