In the previous week, I successfully completed modifying and testing the GUI, ensuring that it works as intended. My goal this week was to tackle the issue I was facing while subscribing to the webcam node.

To ensure there were no issues with the RADI container, I placed my webcam test scripts within the container. By accessing the container through the entrypoint /bin/bash, I checked their functionality using two separate terminals. Since bash doesn’t support a GUI interface, I printed the pixel values of the input webcam feed as shown below:

With this test, I confirmed that the container had no issues. In the follow line exercise, we had been using a separate camera.py script that subscribes to the webcam node and obtains the feed. I decided to omit it altogether and include the entire functionality within the HAL.py file. Below is the updated version of the HAL.py file:

When running the exercise, I obtained the webcam feed perfectly, as seen in the video below:
