I just installed a new security cam system, and one of the things it allows me to do is to stream full quality RTSP streams. I would love to have a small window in the corner of my TV (a la PIP) to view my security camera (So when I am home and waiting for a package, I can see the delivery person).

Is there anything that supports this functionality today? I downloaded VLC because the desktop app does this, but the Android TV version seems very limited.

Any suggestions?
