Я занимаюсь разработкой android phone remote control + VB.NET TCP server - mplayer. Я использую mplayer в режиме slave. Я посылаю команду из приложения для Android на VB.NET TCP сервер. Затем команда отправит в mplayer.
Я покажу некоторый код, который контролирует и отправляет mplayer нужные команды, но серверная часть еще не закончена. Кодирование еще не закончено, но я надеюсь, что оно вам пригодится.
