@sujoyu Thank you. Now I realized what’s wrong. Global is a global variable, but I don’t know why on some machines (maybe python version?) it works, but others will show name 'Global' is not defined.

@Muplex Pass the variable using function arg or just add global Global on the start of the functions (capture()andprocess()) may work. I will fix this soon.

Hi Muplex. The fixed example is following link. https://gist.github.com/sujoyu/ad36b2fef0f0e215d6ee1d093d925e63 I’m not a Python expert too. It may not be a best way.

Additionally, in my low spec but 2 cores ４threads machine, following code is faster than the original.

Change line 125

worker_num = cpu_count()

worker_num = cpu_count() - 1

- 1 indicates count of capturing process.
