The video shows widget discovery and communication across two instances of the player, on the same machine. I tested the same between a PC and a Mac. Other colleagues tested the same between a PC and a phone.
Warning: the video is quite large, so you should be prepared to switch to 1080p and full screen to see anything.
What is shown:
– starting a light bulb application from the Intel UPnP tools
– starting a GPAC player, with the “gui” widget manager and a specific light switch widget
– the light switch widget discovers the Intel light bulb and binds to it: clicking on the switch turns on and off the Intel light bulb, thus demonstrating the communication between a native application and a widget.
– another GPAC player is started and discovery and communication is demonstrated with two other widget pairs.
