GstTagXmpWriter — Interface for elements that provide XMP serialization

Functions

void	gst_tag_xmp_writer_add_all_schemas ()
void	gst_tag_xmp_writer_add_schema ()
gboolean	gst_tag_xmp_writer_has_schema ()
void	gst_tag_xmp_writer_remove_schema ()

GstBuffer *	gst_tag_xmp_writer_tag_list_to_xmp_buffer ()

Description

This interface is implemented by elements that are able to do XMP serialization. Examples for such elements are jifmux and qtmux.

Applications can use this interface to configure which XMP schemas should be used when serializing tags into XMP. Schemas are represented by their names, a full list of the supported schemas can be obtained from gst_tag_xmp_list_schemas(). By default, all schemas are used.

Functions

gst_tag_xmp_writer_add_all_schemas ()

void
gst_tag_xmp_writer_add_all_schemas (GstTagXmpWriter *config);

Adds all available XMP schemas to the configuration. Meaning that all will be used.

Parameters

config

a GstTagXmpWriter

gst_tag_xmp_writer_add_schema ()

void
gst_tag_xmp_writer_add_schema (GstTagXmpWriter *config,
                               const gchar *schema);

Adds schema to the list schemas

Parameters

config	a GstTagXmpWriter
schema	the schema to be added

gst_tag_xmp_writer_has_schema ()

gboolean
gst_tag_xmp_writer_has_schema (GstTagXmpWriter *config,
                               const gchar *schema);

Checks if schema is going to be used

Parameters

config	a GstTagXmpWriter
schema	the schema to test

Returns

TRUE if it is going to be used

gst_tag_xmp_writer_remove_schema ()

void
gst_tag_xmp_writer_remove_schema (GstTagXmpWriter *config,
                                  const gchar *schema);

Removes a schema from the list of schemas to use. Nothing is done if the schema wasn't in the list

Parameters

config	a GstTagXmpWriter
schema	the schema to remove

gst_tag_xmp_writer_remove_all_schemas ()

void
gst_tag_xmp_writer_remove_all_schemas (GstTagXmpWriter *config);

Removes all schemas from the list of schemas to use. Meaning that no XMP will be generated.

Parameters

config

a GstTagXmpWriter

gst_tag_xmp_writer_tag_list_to_xmp_buffer ()

GstBuffer *
gst_tag_xmp_writer_tag_list_to_xmp_buffer
                               (GstTagXmpWriter *config,
                                const GstTagList *taglist,
                                gboolean read_only);
