This demo plays __media/oggs/clip.ogg__ (be sure to put one there before testing) and prints some benchmarking information.

!!!Legend
* __Frame number__ - the index of the currently displayed frame
* __Frames dropped__ - number of frames that couldn't be displayed to keep the video clip in sync
* __Video time__ - current time in seconds of the playing video
* __Decoding time__ - average time it took to decode the last frame,(in milliseconds)
* __YUV--RGB time__ - average time it took to decode YUV pixels to an RGB buffer
* __TexBlit time__ - average time it took to upload the current frame from RAM to the texture buffer on the display card
* __Time per frame__ - average number of milliseconds it takes to prepare one video frame
* __Max FPS__ - how many frames per second can be prepared (estimated)
* __Precached frames__ - how many frames are prepared in advance

!!!Code
The code is a modified and stripped down version of OGRE's CEGUI demo. It uses OGRE's sample framework headers.
The only demo relevant code is located in the ''ClipListener'' class and ''frameStarted()'' function.

* The demo loads __clip.ogg__ located in one of the resource locations.

!!!Material
* located in __demos/media/materials/scripts/Example.material__

As you can see, displaying a video in OGRE is as simple as putting a few lines in the material file. 
See ((TheoraVideoPlugin Materials|Material documentation)) for explanations of these parameters.
