This is done, because there might be some special conditions for the
player to work. For example on fc2live a websocket has to be open while
the player is running. The SiteUI can handle these cases transparently.
Since the JavaFX integrated browser does not work reliably for recaptcha and in general does not behave like standard browsers, I now use an external browser for the logins. The dependency to javafx-web has been removed.
The external browser is based on electron, which uses chromium as internal browser. The implementation can be found at https://github.com/0xboobface/ctbrec-minimal-browser
The browser is a minimal browser, which only shows the web page content without any other controls. It is launched by ctbrec in a new process and remote controlled over a socket connection. I first tried to control it via
stdin/stdout, but it turns out, that stdin is not supported by electron on windows.
Add synchronized modifier to the login methods, so that only one thread
at a time tries to login. All the following threads then should be able
to use the session cookies
