Support for ATEM Upstream Keyers

[lukastheonly]

Hello
I use Tallyarbiter once per month and I love it! But most of my livestreams are virtual productions with greenscreen. To my knowlege tally arbiter only supports program and preview. But when I do Virtual Productions I leave one Media Player in program, switch the still in the media player and the key at the same time.

I think there would be two options in implementing this:

1. Choose a key in the GUI to monitor, if key is onair then light the tally
2. Expand the functionality of the program tally so that if a camera is onair because of a key, then also light the tally, as if the camera was on program. I think thats also how Software Control and Companion handle tally information.

It would be a great help, if this will get implemented some day. I think there are also other use cases for it. Forexample if some lyrics gets displayed on program with a greenscreen. Sometimes the media person is a bit worried wheter the key is still onair or not and therefore wheter he has to stay on a green image or if he can prepare the next part. If tally information would get implemented like i discribed above then I could just give a tally to the person responsible for lyrics and we are all set...

Btw. there are workarounds to get tally arbiter to work with a virtual productions, but it is very annoying, very tricky to use and involves using macros to change the preview to the onair camera and then rewrite the tally code to handle preview as program. Not ideal...
