 Summary: gst_caps_intersect() returns NULL for empty intersection
 
 gst_caps_intersect() returns NULL if the intersection is empty, even though
 NULL caps has the opposite meaning.  I suggest having it return
 GST_CAPS_EMPTY instead, and change other caps math functions to handle
 GST_CAPS_EMPTY properly.

+I don't think it's wrong. Basically, NULL as caps on a pad template or
+as a return value of _getcaps() means 'anything', but NULL as an
+intersection means 'nothing' - the combination of these still means
+'anything'.
+
+This is somewhat insonsistent, but it makes sense.
