  92 <p>
  93 This element encodes raw video into a Theora stream.
  94 <a class="ulink" href="http://www.theora.org/" target="_top">Theora</a> is a royalty-free
  95 video codec maintained by the <a class="ulink" href="http://www.xiph.org/" target="_top">Xiph.org
  96 Foundation</a>, based on the VP3 codec.
  97 </p>
  98 <p>
  99 The theora codec internally only supports encoding of images that are a
 100 multiple of 16 pixels in both X and Y direction. It is however perfectly
 101 possible to encode images with other dimensions because an arbitrary
 102 rectangular cropping region can be set up. This element will automatically
 103 set up a correct cropping region if the dimensions are not multiples of 16
 104 pixels.
 105 </p>
 106 <p>
 107 To control the quality of the encoding, the <span class="type">"bitrate"</span> and
 108 <span class="type">"quality"</span> properties can be used. These two properties are
 109 mutualy exclusive. Setting the bitrate property will produce a constant
 110 bitrate (CBR) stream while setting the quality property will produce a
 111 variable bitrate (VBR) stream.
