While the GNOME desktop environment already offers a few ways for users to stream to Chromecast, AirPlay, or Miracast devices, such as the VLC Media Player, Miracast support isn’t at its best right now due to the use of the H.264 or H.265 codecs, so Benjamin Berg has been trying to fix this problem with a new app. Meet GNOME Screencaster, a graphical tool that will allow you to stream your display to a Miracast device through a Wi-Fi connection. The app uses the NetworkManager utility and requires a Direct Wi???Fi connection to be established first, and an RTSP (Real Time Streaming Protocol) server.
