TagList

this this(GstTagList* gstTagList, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Creates a new empty GstTagList.
this this(string str): Deserializes a tag list.
this this(void* varArgs): Just like gst_tag_list_new(), only that it takes a va_list argument. Useful mostly for language bindings.

Functions

addValist void addValist(GstTagMergeMode mode, string tag, void* varArgs): Sets the values for the given tags using the specified mode.
addValistValues void addValistValues(GstTagMergeMode mode, string tag, void* varArgs): Sets the GValues for the given tags using the specified mode.
addValue void addValue(GstTagMergeMode mode, string tag, Value value): Sets the GValue for a given tag using the specified mode.
foreach_ void foreach_(GstTagForeachFunc func, void* userData): Calls the given function for each tag inside the tag list. Note that if there is no tag, the function won't be called at all.
getBoolean bool getBoolean(string tag, bool value): Copies the contents for the given tag into the value, merging multiple values into one if multiple values are associated with the tag.
getBooleanIndex bool getBooleanIndex(string tag, uint index, bool value): Gets the value that is at the given index for the given tag in the given list.
getDate bool getDate(string tag, Date value): Copies the first date for the given tag in the taglist into the variable pointed to by @value. Free the date with g_date_free() when it is no longer needed.
getDateIndex bool getDateIndex(string tag, uint index, Date value): Gets the date that is at the given index for the given tag in the given list and copies it into the variable pointed to by @value. Free the date with g_date_free() when it is no longer needed.

getIntIndex bool getIntIndex(string tag, uint index, int value): Gets the value that is at the given index for the given tag in the given list.
getPointer bool getPointer(string tag, void* value): Copies the contents for the given tag into the value, merging multiple values into one if multiple values are associated with the tag.
getPointerIndex bool getPointerIndex(string tag, uint index, void* value): Gets the value that is at the given index for the given tag in the given list.
getSample bool getSample(string tag, Sample sample): Copies the first sample for the given tag in the taglist into the variable pointed to by @sample. Free the sample with gst_sample_unref() when it is no longer needed. You can retrieve the buffer from the sample using gst_sample_get_buffer() and the associated caps (if any) with gst_sample_get_caps().
getSampleIndex bool getSampleIndex(string tag, uint index, Sample sample): Gets the sample that is at the given index for the given tag in the given list and copies it into the variable pointed to by @sample. Free the sample with gst_sample_unref() when it is no longer needed. You can retrieve the buffer from the sample using gst_sample_get_buffer() and the associated caps (if any) with gst_sample_get_caps().
getScope GstTagScope getScope(): Gets the scope of @list.
getString bool getString(string tag, string value): Copies the contents for the given tag into the value, possibly merging multiple values into one if multiple values are associated with the tag.
getStringIndex bool getStringIndex(string tag, uint index, string value): Gets the value that is at the given index for the given tag in the given list.
getStruct void* getStruct(): the main Gtk struct as a void*
getTagListStruct GstTagList* getTagListStruct(bool transferOwnership): Get the main Gtk struct
getTagSize uint getTagSize(string tag): Checks how many value are stored in this tag list for the given tag.
getUint bool getUint(string tag, uint value): Copies the contents for the given tag into the value, merging multiple values into one if multiple values are associated with the tag.
getUint64 bool getUint64(string tag, ulong value): Copies the contents for the given tag into the value, merging multiple values into one if multiple values are associated with the tag.
getUint64Index bool getUint64Index(string tag, uint index, ulong value): Gets the value that is at the given index for the given tag in the given list.
getUintIndex bool getUintIndex(string tag, uint index, uint value): Gets the value that is at the given index for the given tag in the given list.
getValueIndex Value getValueIndex(string tag, uint index): Gets the value that is at the given index for the given tag in the given list.
insert void insert(TagList from, GstTagMergeMode mode): Inserts the tags of the @from list into the first list using the given mode.
isEmpty bool isEmpty(): Checks if the given taglist is empty.
isEqual bool isEqual(TagList list2): Checks if the two given taglists are equal.
merge TagList merge(TagList list2, GstTagMergeMode mode): Merges the two given lists into a new list. If one of the lists is %NULL, a copy of the other is returned. If both lists are %NULL, %NULL is returned.
nTags int nTags(): Get the number of tags in @list.
nthTagName string nthTagName(uint index): Get the name of the tag in @list at @index.
peekStringIndex bool peekStringIndex(string tag, uint index, string value): Peeks at the value that is at the given index for the given tag in the given list.
removeTag void removeTag(string tag): Removes the given tag from the taglist.

toString string toString(): Serializes a tag list to a string.

Static functions

copyValue bool copyValue(Value dest, TagList list, string tag): Copies the contents for the given tag into the value, merging multiple values into one if multiple values are associated with the tag. You must g_value_unset() the value after use.
exists bool exists(string tag): Checks if the given type is already registered.
getDescription string getDescription(string tag): Returns the human-readable description of this tag, You must not change or free this string.
getFlag GstTagFlag getFlag(string tag): Gets the flag of @tag.
getNick string getNick(string tag): Returns the human-readable name of this tag, You must not change or free this string.
getType GType getType(string tag): Gets the #GType used for this tag.
isFixed bool isFixed(string tag): Checks if the given tag is fixed. A fixed tag can only contain one value. Unfixed tags can contain lists of values.
mergeStringsWithComma void mergeStringsWithComma(Value dest, Value src): This is a convenience function for the func argument of gst_tag_register(). It concatenates all given strings using a comma. The tag must be registered as a G_TYPE_STRING or this function will fail.
mergeUseFirst void mergeUseFirst(Value dest, Value src): This is a convenience function for the func argument of gst_tag_register(). It creates a copy of the first value from the list.
register void register(string name, GstTagFlag flag, GType type, string nick, string 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.
registerStatic void registerStatic(string name, GstTagFlag flag, GType type, string nick, string blurb, GstTagMergeFunc func): Registers a new tag type for the use with GStreamer's type system.
