<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/tag/gsttagdemux.c">Provides a base class for demuxing tags at the beginning or end of a
|
|
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.
|
|
|
|
## Deriving from GstTagDemux
|
|
|
|
Subclasses have to do four things:
|
|
|
|
* In their base init function, they must add a pad template for the sink
|
|
pad to the element class, describing the media type they can parse in
|
|
the caps of the pad template.
|
|
* In their class init function, they must override
|
|
GST_TAG_DEMUX_CLASS(demux_klass)->identify_tag with their own identify
|
|
function.
|
|
* In their class init function, they must override
|
|
GST_TAG_DEMUX_CLASS(demux_klass)->parse_tag with their own parse
|
|
function.
|
|
* In their class init function, they must also set
|
|
GST_TAG_DEMUX_CLASS(demux_klass)->min_start_size and/or
|
|
GST_TAG_DEMUX_CLASS(demux_klass)->min_end_size to the minimum size required
|
|
for the identify function to decide whether the stream has a supported tag
|
|
or not. A class parsing ID3v1 tags, for example, would set min_end_size to
|
|
128 bytes.</doc>

Subclasses have to do the following things:

* In their base init function, they must add pad templates for the sink

pad and the source pad to the element class, describing the media type
|

they accept and output in the caps of the pad template.

* In their class init function, they must override the

|
|
GST_TAG_MUX_CLASS(mux_klass)->render_end_tag vfuncs and set up a render

#GST_TAG_PREVIEW_IMAGE) from the encoded image data and an (optional) image
|
|
type.
|
|
|
|
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
|
|
the special tag name.
|
|
|
|
This function will do various checks and typefind the encoded image
|
|
data (we can't trust the declared mime type).</doc>
