Video library | Playback | Codecinfo |
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
- Video codecinfo window as seen in stable Kodi v14.x and newer builds.
Information is split into 6 lines of text:
- Audio information - Demuxer
- Audio information - Player
- Video information - Demuxer
- Video information - Player
- General playback information C
- Windowing and System CPU information

Windowing information | Breakdown |
fps:24.00 | How many frames per second the user interface is rendering.
Note: NOT VIDEO FPS. In past versions of Kodi/XBMC (before v15) this value reported the estimated frames per second for the actual video itself, but was horribly inaccurate most of the time. Due to those inaccuracies, and various other code changes, the setting has been changed to only report what FPS the graphical interface (the buttons, menus, etc) is being rendered at. This doesn't actually mean anything for most users, but just understand that this no longer has anything to do with the video FPS. If you want to check if your video playback is working as it should, watch the skip and drop values. If those stay low, nothing to worry about. Increasing skip value means, that video frames cannot be rendered in time. If you even see dropping, then it's our last resort, as the system seems to be too slow to play that video and we told the decoder to throw away complete frames. |
