stream and handles things like typefinding, querying, seeking, and
different modes of operation (chain-based, pull_range-based, and providing
downstream elements with random access if upstream supports that). The tag
is stripped from the output, and all offsets are adjusted for the tag
sizes, so that to the downstream element the stream will appear as if
there was no tag at all. Also, once the tag has been parsed, GstTagDemux
will try to determine the media type of the resulting stream and add a
source pad with the appropriate caps in order to facilitate auto-plugging.

Background: cover art and other images in tags are usually stored as a
blob of binary image data, often accompanied by a MIME type or some other
content type string (e.g. 'png', 'jpeg', 'jpg'). Sometimes there is also an
'image type' to indicate what kind of image this is (e.g. front cover,
back cover, artist, etc.). The image data may also be an URI to the image
rather than the image itself.
In GStreamer, image tags are #GstSample<!-- -->s containing the raw image
data, with the sample caps describing the content type of the image
(e.g. image/jpeg, image/png, text/uri-list). The sample info may contain
an additional 'image-type' field of #GstTagImageType to describe
the type of image (front cover, back cover etc.). #GST_TAG_PREVIEW_IMAGE
tags should not carry an image type, their type is already indicated via
