Actually, it won't work with the current version because of an adb bug ("adb reverse" does not work over "adb connect"): https://issuetracker.google.com/issues/37066218

The solution would be to change the direction of the connection, and use "adb forward", but then scrcpy would try to connect before the server is started, so it would need to retry until connected (and the error would not be noticed on connect, but on first read, due to the tunnel).

Working over "adb connect" would be good, though.
