Future.png FUTURE Krypton FEATURE:
The codecinfo window/overlay normally contains information about the currently playing media, such as video and audio codecs, frame skips, decoding method, etc. Starting in Kodi v17 most of this information has been moved to a new window called PlayerProcessInfo.

Default keymaps will be adjusted to use this new window (i.e., the "o" key will automatically use the new window). Custom keymaps should change CodecInfo to PlayerProcessInfo

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).
