#include <gst/tag/tag.h> guint gst_tag_id3_genre_count (void); const gchar* gst_tag_id3_genre_get (const guint id); GstTagList* gst_tag_list_new_from_id3v1 (const guint8 *data); const gchar* gst_tag_from_id3_tag (const gchar *id3_tag); const gchar* gst_tag_from_id3_user_tag (const gchar *type, const gchar *id3_user_tag); const gchar* gst_tag_to_id3_tag (const gchar *gst_tag);
Contains various utility functions for plugins to parse or create ID3 tags and map ID3v2 identifiers to and from GStreamer identifiers.
guint gst_tag_id3_genre_count (void);
Gets the number of ID3v1 genres that can be identified. Winamp genres are included.
| Returns : | the number of ID3v1 genres that can be identified |
const gchar* gst_tag_id3_genre_get (const guint id);
Gets the ID3v1 genre name for a given ID.
id : |
ID of genre to query |
| Returns : | the genre or NULL if no genre is associated with that ID. |
GstTagList* gst_tag_list_new_from_id3v1 (const guint8 *data);
Parses the data containing an ID3v1 tag and returns a GstTagList from the parsed data.
data : |
128 bytes of data containing the ID3v1 tag |
| Returns : | A new tag list or NULL if the data was not an ID3v1 tag. |
const gchar* gst_tag_from_id3_tag (const gchar *id3_tag);
Looks up the GStreamer tag for a ID3v2 tag.
id3_tag : |
ID3v2 tag to convert to GStreamer tag |
| Returns : | The corresponding GStreamer tag or NULL if none exists. |
const gchar* gst_tag_from_id3_user_tag (const gchar *type,
const gchar *id3_user_tag);
Looks up the GStreamer tag for an ID3v2 user tag (e.g. description in TXXX frame or owner in UFID frame).
type : |
the type of ID3v2 user tag (e.g. "TXXX" or "UDIF") |
id3_user_tag : |
ID3v2 user tag to convert to GStreamer tag |
| Returns : | The corresponding GStreamer tag or NULL if none exists. |
