I have a number of activities working that all assume everything is off in the beginning state. Once I have the TV, AVP, and amps on, I’d like to be able to simply switch my HDMI video sources without powering everything down and starting up again with a new Activity. In many cases, all I need to be able to do is send a command to the HDMI matrix switch to select a new input. However, in a couple of cases I also need to be able to power on the new video source video (e.g., watch a CATV source and want to watch a BluRay). I’ve tried a couple things but neither has worked satisfactorily.
I tried setting a new Activity to power on the new source and switch the matric switcher but as soon as I select the new Activity, it triggers the set of Stop actions that are defined for the first activity, so my TV, AVP, and amps all turn off.
I tried using Design to add a custom button for each video source. I have it working where the button can switch the matrix switcher and turn on the BluRay player but I don’t see a way to make the new video source the primary device so its controls show up on the iPad.
What is the best way to switch video sources without switching everything else off and on?
