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 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.
|
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.
|
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).
|
the type of ID3v2 user tag (e.g. "TXXX" or "UDIF") |
|
ID3v2 user tag to convert to GStreamer tag |
Returns : |
The corresponding GStreamer tag or NULL if none exists. |
const gchar * gst_tag_to_id3_tag (const gchar *gst_tag
);
Looks up the ID3v2 tag for a GStreamer tag.
|
GStreamer tag to convert to vorbiscomment tag |
Returns : |
The corresponding ID3v2 tag or NULL if none exists. |
gboolean gst_tag_list_add_id3_image (GstTagList *tag_list
,const guint8 *image_data
,guint image_data_len
,guint id3_picture_type
);
Adds an image from an ID3 APIC frame (or similar, such as used in FLAC)
to the given tag list. Also see gst_tag_image_data_to_image_buffer()
for
more information on image tags in GStreamer.
|
a tag list |
|
the (encoded) image |
|
the length of the encoded image data at image_data
|
|
picture type as per the ID3 (v2.4.0) specification for the APIC frame (0 = unknown/other) |
Returns : |
TRUE if the image was processed, otherwise FALSE
