I'm confused by all of the new data. Can you summarize? You have tested with 2 different USB cameras: Lepton and c270. You have tested with 3 viewers: QGC, VLC, and ffplay. You have tested with 2 applications: voxl-uvc-server and voxl-streamer. Only one network connection: Microhard. Can you also try a MIPI camera instead of a USB camera? Then can you create a matrix saying which ones worked and which ones didn't?
