Last Sunday I posted, no results. Trying again. Use Windows 10 and have run streaming with camera on OBS. Camera suddenly doesn't show on OBS. Use Elagato cam link. Tried OBS update to 27.2.4 - no help. Have tried a bunch of options & tests - no results. Tested the cam link and results said its ok. When I plug in a HDMI cable direct and don't use Elegato, OBS suddenly recognizes the PTZ camera. What to do?
