| Value | Meaning |
|---|---|
| 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()). |
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.
