When using SSCASN Webcam or another webcam library, how can I avoid hardcoding constraints and make the code more robust?

Avoid hardcoding specific values for width, height, and frame rate. Instead, query the webcam's capabilities, if possible (though often limited). Provide a user interface where users can select from a range of supported resolutions. Use a fallback mechanism to choose default constraints if the user doesn't make a selection or if querying capabilities fails. Implement robust error handling to gracefully handle cases where the webcam is not available or cannot meet the selected constraints.
