/**
 * GstCapsFeatures can optionally be set on a GstCaps to add requirements
 * for additional features for a specific GstStructure. Caps structures with
 * the same name but with a non-equal set of caps features are not compatible.
 * If a pad supports multiple sets of features it has to add multiple equal
 * structures with different feature sets to the caps.
 *
 * Empty GstCapsFeatures are equivalent with the GstCapsFeatures that only
 * contain GST_CAPS_FEATURE_MEMORY_SYSTEM_MEMORY. ANY GstCapsFeatures as
 * created by gst_caps_features_new_any() are equal to any other GstCapsFeatures
 * and can be used to specify that any GstCapsFeatures would be supported, e.g.
 * for elements that don't touch buffer memory. GstCaps with ANY GstCapsFeatures
 * are considered non-fixed and during negotiation some GstCapsFeatures have
 * to be selected.
 *
 * Examples for caps features would be the requirement of a specific GstMemory
 * types or the requirement of having a specific GstMeta on the buffer. Features
 * are given as a string of the format "memory:GstMemoryTypeName" or
 * "meta:GstMetaAPIName".
