Cleanup.png This page or section may require cleanup, updating, spellchecking, reformatting and/or updated images. Please improve this page if you can. The discussion page may contain suggestions.


Whilst XBMC is playing media on screen you can activate the codecinfo overlay O key on keyboard or Guide on remote. This normally appears as white text on a black background bar located near the top of the screen (dependent on the skin being used). The codecinfo overlay displays a number of real time variables describing detailed information on the codecs currently in use.

  • Audio information - provided by both the Demuxer and the Player
  • Video information - provided by both the Demuxer and the Player
  • General playback information C
  • Windowing and System CPU information
  • Sync to screen information
