"RuntimeError: generator raised StopIteration" error message while processing

[DJTacki]

Dear excitoon,

I also would like to thank for your effort. Your project offers me exactly what i need to do. However, i got the following error message running on Win x64 Python 3.7.1 (Spyder IDE):

RuntimeError: generator raised StopIteration

Please let me know if i could provide additional information, and will thank you if you have the chance to look at my problem.

With further attempts to make it work, it seems that the issue is related with the Python3.7, as it is working just fine with Python3.6.

[excitoon]

Hi. It should work fine with Python 3.7. But this error looks strange for me. Is there any work to do for your file (at least one quiet region)? Can you give me a chance reproducing it providing your video file or fragment of it?

[DJTacki]

Sure, i was able to process the following video with 3.6.

[excitoon]

Fixed it. It was this thing: https://www.juandebravo.com/2018/11/09/python-37-stop-iteration/ . May I use your video for a public collection of tests?

[DJTacki]

Thanks for your work. It is not my video, i downloaded it from youtube as a sample, so i don't think it would be a wise step to use in publicly. Sorry for that.

[excitoon]

Okay, that's fine.
