Yes. When you click HLS, you get the HLS stream, which plays in a 3rd party player. It is currently the only way to view live
Blue Iris video in H.264 format in nearly any browser. You can even right click on the HLS stream in UI2 and it gives you the option to open it in a new tab, and what actually happens is it loads a little page called livestream.htm which I built specifically to load an HLS stream and nothing more.
Whereas when you use Chrome, canvas, and H.264 streaming, it uses an entirely different streaming method and player code.
