@GST_CAPS_INTERSECT_ZIG_ZAG tries to preserve overall order of both caps
by iterating on the caps' structures as the following matrix shows:
|[
caps1
+-------------
| 1 2 4 7
caps2 | 3 5 8 10
| 6 9 11 12
]|
Used when there is no explicit precedence of one caps over the other. e.g.
tee's sink pad getcaps function, it will probe its src pad peers' for their
caps and intersect them with this mode.
@GST_CAPS_INTERSECT_FIRST is useful when an element wants to preserve
another element's caps priority order when intersecting with its own caps.
