Codecinfo
|
Whilst XBMC is playing media on screen you can activate the codecinfo overlay O key on keyboard or Guide on remote. 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.
Current stable builds
- Video codecinfo window as seen in stable XBMC v12.x "Frodo" builds.
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
