I have a Barlus Underwater Camera. The live video looks terrific when monitoring through the VMS software used to control and configure the camera. However, when selecting the camera as a Source in OBS, it takes maybe 10 seconds for the Preview to display the video. Then, after video is finally displayed, it runs for a few seconds, freezes, runs some more, etc. Camera is connected via wifi extender, upload speed at 15Mbps and bit rate at 8000. Along with VMS, video also plays well in VLC. Issue likely then something within OBS.
