GstIndex Generate indexes on objects GstIndex is used to generate a stream index of one or more elements in a pipeline. #GstIndexFactory The basic element of an index. @type: @id: A group of related entries in an index. @groupnum: @entries: @certainty: @peergroup: The certainty of a group in the index. @GST_INDEX_UNKNOWN: accuracy is not known @GST_INDEX_CERTAIN: accuracy is perfect @GST_INDEX_FUZZY: accuracy is fuzzy The different types of entries in the index. @GST_INDEX_ENTRY_ID: This entry is an id that maps an index id to its owner object @GST_INDEX_ENTRY_ASSOCIATION: This entry is an association between formats @GST_INDEX_ENTRY_OBJECT: An object @GST_INDEX_ENTRY_FORMAT: A format definition Specify the method to find an index entry in the index. @GST_INDEX_LOOKUP_EXACT: There has to be an exact indexentry with the given format/value @GST_INDEX_LOOKUP_BEFORE: The exact entry or the one before it @GST_INDEX_LOOKUP_AFTER: The exact entry or the one after it Get the number of associations in the entry. @entry: The entry to query Get the flags for this entry @entry: The entry to query Get the i-th format of the entry. @entry: The entry to query @i: The format index Get the i-th value of the entry. @entry: The entry to query @i: The value index An association in an entry. @format: the format of the association @value: the value of the association flags for an association entry @GST_ASSOCIATION_FLAG_NONE: no extra flags @GST_ASSOCIATION_FLAG_KEY_UNIT: the entry marks a key unit, a key unit is one that marks a place where one can randomly seek to. @GST_ASSOCIATION_FLAG_LAST: extra user defined flags should start here. Get the format of the format entry @entry: The entry to query Get the key of the format entry @entry: The entry to query Get the description of the id entry @entry: The entry to query Function to filter out entries in the index. @index: The index being queried @entry: The entry to be added. @Returns: This function should return TRUE if the entry is to be added to the index, FALSE otherwise. Function to resolve ids to writer descriptions. @index: the index being queried. @writer: The object that wants to write @writer_id: A pointer to the id that has to be assigned to this writer @writer_string: A description of the writer. @user_data: user_data as registered @Returns: TRUE if an id could be assigned to the writer. The GstIndex object @Returns: @index: @Returns: @index: @Returns: @index: @groupnum: @Returns: @index: @certainty: @index: @Returns: @index: @filter: @user_data: @index: @resolver: @user_data: @index: @writer: @id: @Returns: @index: @id: @format: @Returns: @index: @id: @flags: @format: @value: @Varargs: @Returns: @index: @id: @key: @type: @object: @Returns: @index: @id: @description: @Returns: @index: @id: @method: @flags: @format: @value: @Returns: @index: @id: @method: @flags: @format: @value: @func: @user_data: @Returns: @entry: @entry: @format: @value: @Returns: Is emited when a new entry is added to the index. @gstindex: the object which received the signal. @arg1: The entry added to the index.
