Whilst Kodi 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.

Note: The codecinfo screen is not entirely accurate for some of the reported data, due to the fact that the codecinfo screen itself will reduce performance on low powered devices (i.e., Raspberry Pi, some Android/ARM boxes).


Current stable builds

Helix
Video codecinfo window as seen in stable Kodi v14.x and newer builds.

Information is split into 7 lines of text:

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