I've searched using the forum and google direct, have found no mention of Miracast. (Understandably, as it's usually a wifi-direct connection that ignores existing networks.)
However, there is a "[Miracast over Infrastructure] protocol. https://github.com/MicrosoftDocs/windows-itpro-docs/blob/master/devices/surface-hub/miracast-over-infrastructure.md seems to be a good intro. (It's not MS Surface specific.) The use case is I'd like to be able to "cast" from a device (desktop) plugged in via ethernet to an OpenWRT router/device, to another device (especially an Xbox One), without having to install a wifi adapter.
Has anyone has any experience with or looked into this?
