Description
Contains various utility functions for plugins to parse or create vorbiscomments and map them to and from GstTagLists.
Functions
gst_tag_from_vorbis_tag ()
const gchar *
gst_tag_from_vorbis_tag (const gchar *vorbis_tag);
Looks up the GStreamer tag for a vorbiscomment tag.
gst_tag_to_vorbis_tag ()
const gchar *
gst_tag_to_vorbis_tag (const gchar *gst_tag);
Looks up the vorbiscomment tag for a GStreamer tag.
gst_vorbis_tag_add ()
void gst_vorbis_tag_add (GstTagList *list,const gchar *tag,const gchar *value);
Convenience function using gst_tag_from_vorbis_tag(), parsing
a vorbis comment string into the right type and adding it to the
given taglist list
.
Unknown vorbiscomment tags will be added to the tag list in form of a GST_TAG_EXTENDED_COMMENT.
gst_tag_to_vorbis_comments ()
GList * gst_tag_to_vorbis_comments (const GstTagList *list,const gchar *tag);
Creates a new tag list that contains the information parsed out of a vorbiscomment packet.
Returns
A GList of newly-allocated key=value strings. Free with g_list_foreach (list, (GFunc) g_free, NULL) plus g_list_free (list).

Returns
A new GstTagList with all tags that could be extracted from the given vorbiscomment buffer or NULL on error.
gst_tag_list_from_vorbiscomment_buffer ()
GstTagList * gst_tag_list_from_vorbiscomment_buffer (GstBuffer *buffer,const guint8 *id_data,const guint id_data_length,gchar **vendor_string);
