Simple producer/consumer system using python threads to convert a video to grayscale.

Producer Consumer Lab

For this lab I implemented a trivial producer-consumer system using python threads where all coordination is managed by counting and binary semaphores for a system of two producers and two consumers. The producers and consumers will form a simple rendering pipeline using multiple threads. One thread will read frames from a file, a second thread will take those frames and convert them to grayscale, and the third thread will display those frames. The threads will run concurrently.

How to run

Run the following command:

$ python3 ExtractAndDisplay.py

ExtractAndDisplay.py

This file loads a series of frames from a video contained in 'clip.mp4', converts them to grayScale, and displays them with a 42ms delay.

First the video is broken down into frames. Each frame will be extracted in the method extractFrames(), and then it will be converted to grayscale in the method convertFrames(). After being converted, it will be displayed in a video in the method displayFrames().
