I have issues when I try to run multiple videos at once. As soon as I load(not play) four videos, the log starts to fill up with the warnings below.
[2019-09-23 18:34:09.489]  [warning] DeckLink Duo 2 [4-4|1080p5000] late scheduled=276000* decklink=275961 [2019-09-23 18:34:09.503]  [warning] DeckLink Duo 2 [3-3|1080p5000] late scheduled=284000* decklink=283774
The Idea is ti run five videos at one with the batch feature in the NRK fork. The first four to a LED wall and the fifth to TV production.
When running three videos it can start succesfully but ends up with the warnings end drops frames.
The server runs win 10 1903 with NRK server 2.1.8
