How to Use Multiprocessing to Optimize Python Barcode Reader

Previously, I demonstrated how to use OpenCV and Dynamsoft Barcode SDK to build a Python barcode reader. There’s one problem that when barcode decoding takes a long time, the webcam video didn’t play smoothly. I also tried multithread but failed to tackle the issue either due to the Python GIL(Global Interpreter Lock). Now I’m inspired by multiprocessing which is the recommended way to break through the bottleneck.

How to Package and Distribute Python Barcode SDK to PyPi

Previously, I wrote an article sharing how to build Python barcode extension using C/C++ with Dynamsoft Barcode Reader SDK. If Python developers want to use the extension, they have to make it by themselves. It is a little bit inconvenient. A better way is to package the extension and distribute it to PyPi. Then developers could directly install the extension using pip commands.
