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 FPS AT ALL!!!. This is most likely of no value to the user. I wanted to remove it but there was protest by people not knowing what this is about. Actually this has been a cycle counter of the application's main loop which in many cases was almost equal to video FPS. After introduction of dirty regions some while ago this started more and more not to be the value it pretends to be. If you are not interested in fading control of labels or scrolling text, this is not of any interest to you. 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. |
