AutoCast Detect of currently casting

I have set up my TV to pause if my phone rings.
I know I can pause chrome cast with autocast.
Can I check to see if currently casting to chrome cast, then pause chome cast only if casting?

 

Well at the moment if I'm watching TV via my set top box and my phone rings, Tasker sends a command to my IR blaster to pause the TV.
The reason I want to detect if Chrome Cast is being used, is so I can pause Chome Cast instead of the set top box.

 

Hi, any chance to Trap what's currently casting, avec if not with AC?

Thanx

 

Usually there is a notification that someone on your network is casting (with some media controls). You can react to that. However it only appears when the screen is on.
