I own an Elgato Cam Link and never had that issue with my current setup. Can you please let me know which firmware version your OSSC is running on? Also, I know you probably do already, but do you have everything up to date? (OBS, Elgato Cam Link drivers, etc.) Are you capturing the Elgato Cam Link signal directly from OBS or are you using the Elgato Game Capture HD Software/Plugin? Sorry for all the questions but it’ll help with the trouble shooting 😀 Looked great nonetheless!
