ECP docs on launch say “Launches the channel identified by appID. You can follow the appID with a question mark and a list of URL parameters to be sent to the application as an associative array, and passed tyto the RunUserInterface() or Main() entry point.”
but don’t explain that at all, like how to expose the parameter names.
I suspect something like http://RokuIP:8060/launch/appid?voice-command=“play WWOZ”
because via voice command I can indeed get it to launch via “play WWOZ on tunein “
p.s. is there not a parameter value available for keypress/VolumeUp. Possibly something like ?value=5 to increase by 5. If I use keypress it does one notch (too little) and if I do keydown/keyup it does 20 (which is too much)
