MKPlayer customization

The @mediakind/mkplayer-customui-plugin lets you build and customize playback interfaces on top of Bitmovin Player UI V3.

Previously, MKPlayer supported a basic ui: true | false flag to show or hide the default playback UI. The MKCustomUI plugin extends this by enabling full layout, control, behavior, and styling customization.

What you can do

  • Build MKPlayer’s default-style UI

  • Create fully custom playback UIs

  • Configure UI behavior through uiConfig

  • Use responsive UI variants for mobile and browser layouts

  • Style playback controls using CSS class overrides

  • Apply UI updates dynamically at runtime based on screen size, app state, and user context
