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

Gotham ?


In Frodo in fullscreen video playback, the codec information is split into 4 lines of text. In Gotham it splits into 6 lines.

  • 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

Samples from the screen above:
