get_features


Description:

[ Version ( since = "1.2" ) ]
public unowned CapsFeatures? get_features (uint index)

Finds the features in this that has the index 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 structures 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.

You do not need to free or unref the structure returned, it belongs to the Caps.

Parameters:

this

a Caps

index

the index of the structure

Returns:

a pointer to the CapsFeatures corresponding to index
