preview / program tally info during transitions

[PeterMaes]

• I'm submitting a ... [ ] bug report [ ] feature request [ ] question about the decisions made in the repository [x] question about how to use this project

• Summary I am trying to get the real tally info of this module, but could not find the right info so far. During transitions the tally info is showing a red indication on the Preview button (in Atem Software Control). I am using state.video.ME[0].programInput and state.video.ME[0].previewInput to get program and preview state. But during transition these values do not represent the right info. Below the info I have logged (timestamp in front) Immediatly after sending the AutoTransition action I got an event that repeats the previewInput state. To me it seems this is wrong, but maybe I am missing some details here.

1586875643417 state.video.ME[0].programInput= 2 1586875643419 state.video.ME[0].previewInput= 1 1586875652282 KeyPress= AUTO/CUT 1586875652322 state.video.ME[0].previewInput= 1 --- transitions is happening here --- 1586875654302 state.video.ME[0].programInput= 1 1586875654303 state.video.ME[0].previewInput= 2

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)

The events being emitted here are a direct representation of what the atem is sending to the library. The preview & program inputs get swapped at the very end of the transition (you can prove this by hot cutting preview and program during a running transition). Atem Software Control must be changing the colour when it knows that it is in a transition (another property we have defined somewhere)

Perhaps you are after the listVisibleInputs function? https://nrkno.github.io/tv-automation-atem-connection/globals.html#listvisibleinputs This is designed to give the same preview & program state as seen on the multiviewer, and handles transitions, keyers and supersources.

Thanks for your quick and helpfull reply. Indeed this is the function I was looking for !

state.video.ME[0].inTransition (works for both auto transition and manually running the t-bar)
