For each media subtype in the array passed in to the
init(media method, the delegate receives sample buffers carrying data in its native format via the
native parameter if there is media data of that subtype in the media resource.
For all other media subtypes present in the media resource, the delegate receives attributed strings in a common format via the
strings parameter. See CMTextMarkup for the string attributes keys and values that are used in the attributed strings.
