I was imagining that this was a fullscreen mode, given that you had no UI stacked under the video.
The thing about surfaces is that you can configure them as you like every frame. If you have a browser playing multiple videos, each video can be a subsurface, and then when you transition to a fullscreen playback with OSD, you can reconfigure your main surface to be playing the video, and add a single OSD subsurface on top in the right location. Your main surface can transition between being a UI layer and a video layer when it's needed.
