Constructors
gst_tag_list_new
GstTagList * gst_tag_list_new (const gchar * tag, ... ...)
Creates a new taglist and appends the values for the given tags. It expects tag-value pairs like gst_tag_list_add, and a NULL terminator after the last pair. The type of the values is implicit and is documented in the API reference, but can also be queried at runtime with gst_tag_get_type. It is an error to pass a value of a type not matching the tag type into this function. The tag list will make copies of any arguments passed (e.g. strings, buffers).
After creation you might also want to set a GstTagScope on the returned taglist to signal if the contained tags are global or stream tags. By default stream scope is assumes. See gst_tag_list_set_scope.
Free-function: gst_tag_list_unref

gst_tag_list_copy
GstTagList * gst_tag_list_copy (const GstTagList * taglist)
Creates a new GstTagList as a copy of the old taglist. The new taglist will have a refcount of 1, owned by the caller, and will be writable as a result.
Note that this function is the semantic equivalent of a gst_tag_list_ref followed by a gst_tag_list_make_writable. If you only want to hold on to a reference to the data, you should use gst_tag_list_ref.
When you are finished with the taglist, call gst_tag_list_unref on it.
Parameters:

gst_tag_merge_use_first

Parameters:
GValue to copy from
gst_tag_register
gst_tag_register (const gchar * name, GstTagFlag flag, GType type, const gchar * nick, const gchar * blurb, GstTagMergeFunc func)
Registers a new tag type for the use with GStreamer's type system. If a type with that name is already registered, that one is used. The old registration may have used a different type however. So don't rely on your supplied values.
Important: if you do not supply a merge function the implication will be that there can only be one single value for this tag in a tag list and any additional values will silently be discarded when being added (unless GST_TAG_MERGE_REPLACE, GST_TAG_MERGE_REPLACE_ALL, or GST_TAG_MERGE_PREPEND is used as merge mode, in which case the new value will replace the old one in the list).
The merge function will be called from gst_tag_list_copy_value when it is required that one or more values for a tag be condensed into one single value. This may happen from gst_tag_list_get_string, gst_tag_list_get_int, gst_tag_list_get_double etc. What will happen exactly in that case depends on how the tag was registered and if a merge function was supplied and if so which one.
Two default merge functions are provided: gst_tag_merge_use_first and gst_tag_merge_strings_with_comma.
Parameters:
name
–
the name or identifier string
flag
–
a flag describing the type of tag info
type
–
the type this data is in
nick
–
human-readable name
blurb
–
a human-readable description about this tag
func
(
[allow-none])
–
function for merging multiple values of this tag, or NULL
gst_tag_register_static
gst_tag_register_static (const gchar * name, GstTagFlag flag, GType type, const gchar * nick, const gchar * blurb, GstTagMergeFunc func)
Registers a new tag type for the use with GStreamer's type system.
Same as gst_tag_register, but name, nick, and blurb must be static strings or inlined strings, as they will not be copied. (GStreamer plugins will be made resident once loaded, so this function can be used even from dynamically loaded plugins.)
Parameters:
name
–
the name or identifier string (string constant)
flag
–
a flag describing the type of tag info
type
–
the type this data is in
nick
–
human-readable name or short description (string constant)
blurb
–
a human-readable description for this tag (string constant)
func
(
[allow-none])
–
function for merging multiple values of this tag, or NULL

GST_TAG_FLAG_IS_VALID
#define GST_TAG_FLAG_IS_VALID(flag) (((flag) > GST_TAG_FLAG_UNDEFINED) && ((flag) < GST_TAG_FLAG_COUNT))

gst_tag_list_is_writable
#define gst_tag_list_is_writable(taglist) gst_mini_object_is_writable (GST_MINI_OBJECT_CAST (taglist))
Tests if you can safely modify taglist. It is only safe to modify taglist when there is only one owner of the taglist - ie, the refcount is 1.
Parameters:
taglist
–
gst_tag_list_make_writable
#define gst_tag_list_make_writable(taglist) GST_TAG_LIST (gst_mini_object_make_writable (GST_MINI_OBJECT_CAST (taglist)))
Returns a writable copy of taglist.
If there is only one reference count on taglist, the caller must be the owner, and so this function will return the taglist object unchanged. If on the other hand there is more than one reference on the object, a new taglist object will be returned (which will be a copy of taglist). The caller's reference on taglist will be removed, and instead the caller will own a reference to the returned object.
In short, this function unrefs the taglist in the argument and refs the taglist that it returns. Don't access the argument after calling this function. See also: gst_tag_list_ref.
Parameters:
taglist
(
[transfer: full])
–
a writable taglist which may or may not be the same as taglist

GstTagMergeMode
The different tag merging modes are basically replace, overwrite and append, but they can be seen from two directions. Given two taglists: (A) the tags already in the element and (B) the ones that are supplied to the element ( e.g. via gst_tag_setter_merge_tags / gst_tag_setter_add_tags or a GST_EVENT_TAG), how are these tags merged? In the table below this is shown for the cases that a tag exists in the list (A) or does not exists (!A) and combinations thereof.
