| 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 substracting |
| or intersecting. |
