 The first thing you'll need to do is configure your MLB.tv username, password,

 mlbplay --init-config

 The program should ask you for your username and password, then try to find your
 media player (it just looks for mpv or vlc right now.). If it doesn't find it,
 you can enter the full path to whatever you're using. If your player worked with
 mlbviewer, it should work with mlbstreamer. It'll also ask you for your time
 zone so that game times are displayed properly.

 out, etc. The toolbar at the top allows you to select the output resolution and
 some other options.
