[GStreamer (GNOME Bugzilla)]

So in addition to 

+ * It helps pipeline negotiation when the exporter is the upstream element
from
+ * the importer point of view.

It is useful to force dmabuf usage in order to avoid any conversion between
exporter and importer. The elements that cannot handle this caps feature will
just put themself in passthrough mode (videobalance, videoscale, videoconvert
...)
Same idea as between omxvideodec and glimagesin when using memory:EGLImage.

For example if the exporter is gstvaapidecodebin and importer is glimagesink
then the decoder may want to set GST_CAPS_FEATURE_MEMORY_DMABUF to ensure to
terminate the pipeline if importation fails.
