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.
-Instead, the new caps use new mymetypes : {{{video/x-raw-{yuv,rgb,gray}-stereo}}}. The addition of the {{{"-stereo"}}} to the mymetype makes sure that existing plugins won't accept these caps. The new caps that are to replace {{{video/x-raw-{yuv,rgb,gray,etc}}}} could add something like {{{-full}}} during integration of these new caps in order to keep compatibility with existing plugins.

+ * GST_VIDEO3D_LAYOUT_ROW_INTERLEAVED:
+This might need need more variants as:
