GstPadLinkCheck

The amount of checking to be done when linking pads. @GST_PAD_LINK_CHECK_CAPS and @GST_PAD_LINK_CHECK_TEMPLATE_CAPS are mutually exclusive. If both are specified, expensive but safe @GST_PAD_LINK_CHECK_CAPS are performed.

> Only disable some of the checks if you are 100% certain you know the link > will not fail because of hierarchy/caps compatibility failures. If uncertain, > use the default checks (%GST_PAD_LINK_CHECK_DEFAULT) or the regular methods > for linking the pads.

Values

ValueMeaning
NOTHING0

Don't check hierarchy or caps compatibility.

HIERARCHY1

Check the pads have same parents/grandparents. Could be omitted if it is already known that the two elements that own the pads are in the same bin.

TEMPLATE_CAPS2

Check if the pads are compatible by using their template caps. This is much faster than @GST_PAD_LINK_CHECK_CAPS, but would be unsafe e.g. if one pad has %GST_CAPS_ANY.

CAPS4

Check if the pads are compatible by comparing the caps returned by gst_pad_query_caps().

NO_RECONFIGURE8

Disables pushing a reconfigure event when pads are linked.

DEFAULT5

The default checks done when linking pads (i.e. the ones used by gst_pad_link()).
