Whilst XBMC is playing media on screen you can activate the codecinfo overlay O key on a keyboard. 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.

1 Current stable builds

Helix

  • Audio information - Demuxer
  • Audio information - Player
  • Video information - Demuxer
  • Video information - Player
  • General playback information C
  • Windowing and System CPU information
