Mystery MacBookAir Locking

Options

Hello

I am connecting to a Macbook Air that is streaming a video feed.  I am using a HP Laptop running Windows.  The Macbook Air is streaming a live feed that needs to run continuous. Whenever I exit TeamViewer the live feed pauses and Macbook Air locks. 

I have disabled lock computer on exit in the local Teamviewer preferences at the top, as well as in the advanced connection preferences and set to "never".  I have turned off screenlock on the Macbook Air. 

When I connect with Teamviewer I am shown the lock screen on the Macbook Air. Once I login everything is great. Once I exit Teamviewer the Macbook locks and the live stream freezes.

Does anyone have any other suggestions?
