Support on M/E 2

[LOGANO1]

Is it Possible to change the Code so it takes the Tally data of an M/E 2 Mixer from the ME2 and not the Main ME (ME1)

As I've only really worked with an ATEM mini I'm not entirely sure what you mean. Most likely because I'm not sure how M/E 2 works exactly.
I assume that all video inputs would go to both ME's. If so, I would assume that tally indication is pr. Input source, and not pr. ME. Indicating to the camera operator that they are live regardless of what ME they're live on.
Please correct me if I'm wrong.

Else, have you built some tally units already you can demonstrate your issue with?

It is possible to get Program and Preview on each M/E.
Your assumption is correct that all inputs are available to both M/Es
This is a code snippet that I used for a more simple program than yours. Mine was written for the M5 Atom, the coding is not pretty but it works.
Source 0 is M/E1 and Source 1 is M/E2. It should work similar for the large 4M/E units as well.

int ProgramTallyme2 = AtemSwitcher.getProgramInputVideoSource(1);
//delay(5);
int ProgramTallyme1 = AtemSwitcher.getProgramInputVideoSource(0);
// delay(5);
int PreviewTallyme2 = AtemSwitcher.getPreviewInputVideoSource(1);
// delay(5);
int PreviewTallyme1 = AtemSwitcher.getPreviewInputVideoSource(0);

if ((ProgramTallyme2Previous != ProgramTallyme2) || (ProgramTallyme1Previous != ProgramTallyme1) || (PreviewTallyme2Previous != PreviewTallyme2) || (PreviewTallyme1Previous != PreviewTallyme1))
{ // changed?
if ((ProgramTallyme2 == cameraNumber) || (ProgramTallyme1 == cameraNumber))
{ // only program, or program AND preview
fillDisplay(GRB_COLOR_RED);
// delay(5);
}

else if ((PreviewTallyme2 == cameraNumber && ProgramTallyme2 != cameraNumber) || (PreviewTallyme1 == cameraNumber && ProgramTallyme1 != cameraNumber))
{ // only preview
  fillDisplay(GRB_COLOR_GREEN);
 // delay(5);
}

else if (PreviewTallyme2 != cameraNumber && ProgramTallyme2 != cameraNumber && PreviewTallyme1 != cameraNumber && ProgramTallyme1 != cameraNumber)
{ // neither
  fillDisplay(GRB_COLOR_GREY);
 // delay(5);
}

In my case I use one M/E for my inhouse feed and the other M/E for my broadcast feed.
It may be beyond my programming skills but I would like to modify your code to be able to do 2 M/Es.

I like to use Grey (actually dark blue) instead of off when a camera is neither Program or Preview, but that is more a personal preference.

Any hints on modifying your code would be appreciated.
Thanks, Kent
