RTSP Stream Matrix Using OMX Player.

I have been using the attached script for many years now to display 1 RTSP stream at a time with OMX Player on a Raspberry PI. The script will recheck the RTSP stream every 60 seconds for connectivity and if connectivity is lost it will reconnect it. This project is for a script to be created to do the exact same task, except displaying 4 RTSP streams at a time in a matrix (Quad) display format with each window being displayed at the following locations on the screen. RTSP Stream #1 - 0 0 960 540 RTSP Stream #2 - 960 0 1920 540 RTSP Stream #3 - 0 540 960 1080 RTSP Stream #4 - 960 540 1920 1080 Finish project should include a complete script to preform the above task and install script to configure rasperry pi (weezy-rasbian) for any additional packages needed to make script function properly.
