get_features
Description:
Finds the features in this at index, and returns it.
WARNING: This function takes a `const GstCaps *`, but returns a non-const `GstCapsFeatures *`. This is for programming convenience -- the
caller should be aware that features inside a constant Caps should not be modified.
However, if you know the caps are writable, either because you have just copied them or made them writable with gst_caps_make_writable
, you may modify the features returned in the usual way, e.g. with functions like
add.
Parameters:
| this |
a Caps |
| index |
the index of the structure |
Returns:
|
a pointer to the CapsFeatures corresponding to |
