Contains various utility functions for plugins to parse or create vorbiscomments and map them to and from GstTagLists.
const gchar* gst_tag_from_vorbis_tag (const gchar *vorbis_tag);
Looks up the GStreamer tag for a vorbiscommment tag.
| vorbis_tag: | vorbiscomment tag to convert to GStreamer tag | 
| Returns : | The corresponding GStreamer tag or NULL if none exists. | 
const gchar* gst_tag_to_vorbis_tag (const gchar *gst_tag);
Looks up the vorbiscommment tag for a GStreamer tag.
| gst_tag: | GStreamer tag to convert to vorbiscomment tag | 
| Returns : | The corresponding vorbiscommment tag or NULL if none exists. | 
void gst_vorbis_tag_add (GstTagList *list, const gchar *tag, const gchar *value);
| list: | |
| tag: | |
| value: | 
GList* gst_tag_to_vorbis_comments (const GstTagList *list, const gchar *tag);
| list: | |
| tag: | |
| Returns : | 
GstTagList* gst_tag_list_from_vorbiscomment_buffer (const GstBuffer *buffer, const guint8 *id_data, const guint id_data_length, gchar **vendor_string);
Creates a new tag list that contains the information parsed out of a vorbiscomment packet.
| buffer: | buffer to convert | 
| id_data: | identification data at start of stream | 
| id_data_length: | length of identification data | 
| vendor_string: | pointer to a string that should take the vendor string of this vorbis comment or NULL if you don't need it. | 
| Returns : | A new GstTagList with all tags that could be extracted from the given vorbiscomment buffer or NULL on error. | 
GstBuffer* gst_tag_list_to_vorbiscomment_buffer (const GstTagList *list, const guint8 *id_data, const guint id_data_length, const gchar *vendor_string);
Creates a new vorbiscomment buffer from a tag list.
| list: | tag list to convert | 
| id_data: | identification data at start of stream | 
| id_data_length: | length of identification data | 
| vendor_string: | string that describes the vendor string or NULL | 
| Returns : | A new GstBuffer containing a vorbiscomment buffer with all tags that could be converted from the given tag list. |
