TheoraVideoPlugin Player

From Ogre Wiki

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

material SimpleVideo

    pass
    {
      cull_software none
      cull_hardware none
      lighting off

      texture_unit
      {
        texture_source ogg_video
        {
          filename clip.ogg
          precache 50
          play_mode play
        }
      }
    }
  }
}

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