Caps
|
|
----
|
|
|
|
Caps are lighweight refcounted objects describing media types.
|
|
They are composed of an array of GstStructures.
|
|
|
|
Caps are exposed on GstPadTemplates to describe all possible types a
|
|
given pad can handle. They are also stored in the registry along with
|
|
a description of the element.
|
|
|
|
Caps are exposed on the element pads using the _get_caps() pad function.
|
|
This function describes the possible types that the pad can handle or
|
|
produce (see part-pads.txt and part-negotiation.txt).
|
|
|
|
Caps are also attached to buffers to describe to content of the data
|
|
pointed to be the buffer.
|
|
|
|
Various methods exist to work with the media types such as subtracting
|
|
or intersecting.
