Dear community,
with your great support I coded a perceptual-hash-hanger-finder for digitized super8-films.
I got the hangerfinder working in pycharm.
I created an exe with pyinstaller - but outside of pycharm a new pyqt window is opened again and again.
I guess that I have to hide the hangerfinder behind:
if __name__ == "__main__":
to avoid this Behave.
I'm trying to achieve the following:
When the button "button_HF_Start" is clicked, it is checked, if a film, which is to be checked for hangers, is marked with x in excel.
If the film was marked, the hangerfinder starts examining the frames in folder and when this is done, the timestamps are written to excel.
Then the script ends.
Now I'm a bit confused, because I'm not sure how I have to rearrange my script.
I have a big request (and know it takes a lot of effort):
Could you please show me how I have to rearrange my code?
That would be great, because it was much work for you and me and this is the final step (rearrange the script and creating an exe).
Thanks a lot for your help!! I will be very thankful.
this works in pycharm:
