From what I can see, you were pulling 1 full resolution source (VidH) and 1 low resolution source (VidL) channel thru Bridge, then it appears a second low resolution source starting being pulled (VidL went from 1ch to 2ch) and then it exited shortly after.

I also notice that despite VidL being 1 or 2 channels, I don't see any matching bandwidth (0kbit/s).

What are the NDI sources and what is application/device pulling the NDI connections?
