Hello! I'm very new to this and not a programmer (at least in this type of stuff), so please excuse me if I'm misunderstanding something huge. 
I have a rpi3b+ and 1 strip of WS2812B around my TV. My TV is Tizen, so there's no Hyperion app to grab anything put on the screen. I use a firestick 4k (no copyright content/DRM issues 
) and a nintendo switch. Am I able to use the android grabber app on the firestick AND my hdmi grabber for the switch with hyperHDR with the 1 set of LEDs on 1 rpi? (I could not get my LEDs to work with hyperion, only hyperhdr, something related to running root. I tried so many different ways and hyperhdr was the only one that worked.) I'm hoping I could do this rather than having to manually switch hdmi and lose cec/better output because of the capture card I got.
So far I can get the LEDs to work perfectly with the switch using the hdmi capture card and hyperHDR on the rpi. I turned the android grabber app on on the firestick and it did find hyperhdr, but the second I try to make a new instance on hyperhdr for the firestick, the LEDs start flickering and never do the rainbow effect for the app. I'm assuming they're competing and not meant to be used like this? Would the forwarding option in network services be a way of doing what I'm hoping to do? or should I just bite the bullet and get a new card/another way to run the LEDs
Thanks in advance for any help and feel free to tell me if im not understanding something!
