Interfacing with a BlackMagic ATEM mixer
Has anyone interface OpenLP with a BlackMagic ATEM mixer? Our OpenLP PC feeds into an ATEM mixer together with camera feeds. Due to covid we cannot have a live service so all our songs are via lyric videos. What would be really helpful would be able to program up the Service so that when a video file ends, OpenLP would tell the ATEM mixer to make the switch to the next video input. This ought to be possible in a number of ways since there is a published API for the ATEM. Alternatively there are means to control the ATEM via MIDI controls. Before I start looking at this, I was wondering whether anyone has done it before?
Thanks

Paul, did you get this running?
XAPBob, funny you should bring this up since I was revisiting this again last night and had forgotten about my post here!
Sadly the answer is no which is a real shame. Part of me thinks it ought to be possible with either MIDI or OSC calls. I current use of SCS to play lyric videos and to send OSC commands to atemOSC for our livestream. However, I am trying to prepare for being back in church with live services again.
Another thought would be to somehow run commands from OpenLP (eg javascript) to send the OSC messages. However, I can't work out how to do that either!
Any input gratefully received since sadly it looks as if we will be going either to ProPresenter or Proclaim.
@Wilts01 I'm afraid that there's no way currently for OpenLP to do this. Even within OpenLP, there's no broadcast signal to other parts of OpenLP when a video ends.
If you are willing to get your hands dirty, it shouldn't be too difficult to add it to OpenLP, since the code to catch the end of the video is there, we'd just need to broadcast it somehow.
@raoul Thanks for the update. Sadly my coding skills are very limited otherwise I would have looked at helping out.
