@ -793,7 +793,14 @@ gst_caps_get_size (const GstCaps * caps)
* WARNING: This function takes a const GstCaps *, but returns a
* non-const GstStructure *. This is for programming convenience --
* the caller should be aware that structures inside a constant
* #GstCaps should not be modified.
* #GstCaps 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
* structure returned in the usual way, e.g. with functions like
* gst_structure_set_simple().
*
* You do not need to free or unref the structure returned, it
* belongs to the #GstCaps.
*
* Returns: a pointer to the #GstStructure corresponding to @index
