Using the MediaPlayerElement on WebAssembly head requires adding the Uno.WinUI.MediaPlayer.WebAssembly package to the MyApp.Wasm project.


The Uno.WinUI.MediaPlayer.WebAssembly package version must use the same version as the other Uno.WinUI.* packages in your project.


When using UWP APIs and the Uno.UI.* packages, you'll need to install the Uno.UI.MediaPlayer.WebAssembly package instead.


Using the MediaPlayerElement on the Skia+GTK head requires adding the Uno.WinUI.MediaPlayer.Skia.Gtk package to the MyApp.Skia.Gtk project.


The Uno.WinUI.MediaPlayer.Skia.Gtk package version must use the same version as the other Uno.WinUI.* packages in your project.


When using UWP APIs and the Uno.UI.* packages, you'll need to install the Uno.UI.MediaPlayer.Skia.Gtk package instead.

Skia+GTK on Linux

The MediaPlayerElement support is based on libVLC, and needs the system to provide the appropriate libraries to work properly.

You'll need to install the following packages (Debian based distros):

sudo apt-get install libvlc-dev libx11-dev vlc libgtk2.0-0 libx11dev

Skia+GTK on Windows

Running the MediaPlayerElement requires adding the VideoLAN.LibVLC.Windows package to your application.

Future improvement

  • React to audio focus changes (pause/stop playback or reduce audio volume)
  • Subtitles support
  • Languages support
  • Buffering of next playlist element when using MediaPlaybackList
  • Cast to device
  • Playlist for Wasm
  • Download option

Known issues
