I want to develop a slide-show kind of app that could be casted to smart TV, similar to showing a PowerPoint slide show. Standard Miracast solution via the Connect app does not work nicely since the phone resolution does not match the high resolution of the TV; not to count the fact that there is no way to hide the navigation bar with TryEnterFullscreenAsync. The images could be quickly rendered from vector sources. So my question is whether there is a way to generate MP4 on the fly.
