* This element encodes raw video into a VP8 stream.
|
|
|
|
* <ulink url="http://www.webmproject.org">VP8</ulink> is a royalty-free
|
|
|
|
* video codec maintained by <ulink url="http://www.google.com/">Google
|
|
|
|
* </ulink>. It's the successor of On2 VP3, which was the base of the
|
|
|
|
* Theora video codec.
|
|
|
|
*
|
|
|
|
* To control the quality of the encoding, the #GstVP8Enc::bitrate and
|
|
|
|
* #GstVP8Enc::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
|
|
|
|
* variable bitrate (VBR) stream.
