 = Stereo video support in an existing branch =

 

 Stereo caps have been proposed in a Google Summer of Code development branch (see [[http://gitorious.org/video3d/video3d]]).  One of the important points in choosing how to extend existing caps to support a way to specify whether the video stream was stereo or not was the fact that we don't want existing plugins to accept silently a stereo stream and treat it as normal stream, as the interpretation of a {{{width x height}}} buffer is totally different if the buffer is stereo or not.  Therefore, the addition of a field such as {{{"stereo=true"}}} or {{{"channels=2"}}} to existing video caps was not used.
