There were a couple strings containing \(. That is not a valid escape sequence in Python. The escape sequence was meant for GStreamer, and as such either the backslash should be doubled or a raw string must be used. This patch uses the latter for readability. Python 3.13 will print a warning when a invalid escape sequence in a string is found. As a drive-by fix, this patch fixes fixes whitespace issues in the file to make the Python linter happy.
