When MPV is killed externally, non-daemon threads block on I/O operations and Python's interpreter shutdown waits for them indefinitely. Setting daemon=True allows Python to exit cleanly without waiting for these threads.

Summary
WindowsSocket,UnixSocket, andEventHandlerthreads daemon threadsProblem
When MPV is killed externally (e.g., Cmd+Q on macOS), the non-daemon threads block on I/O operations (
socket.recv(),queue.get()) and Python's interpreter shutdown waits for them indefinitely. This causes applications using this library to hang for minutes until MPV fully exits.Solution
Setting
self.daemon = Trueon all internal threads allows Python to exit cleanly without waiting for these threads to finish.
