* multiple of 16 pixels in both X and Y direction. It is however perfectly
* possible to encode images with other dimensions because an arbitrary
* rectangular cropping region can be set up. This element will automatically
* set up a correct cropping region if the dimensions are not multiples of 16
* pixels.

* #GstTheoraEnc::quality properties can be used. These two properties are
* mutualy exclusive. Setting the bitrate property will produce a constant
* bitrate (CBR) stream while setting the quality property will produce a
