This is used - * during the format negotiation process to try to pick the best format to - * use to minimize the number of necessary conversions. Each filter gives a - * list of the formats supported by each input and output pad. The list - * given for each pad need not be distinct - they may be references to the - * same list of formats, as is often the case when a filter supports multiple - * formats, but will always output the same format as it is given in input. - * - * In this way, a list of possible input formats and a list of possible - * output formats are associated with each link. When a set of formats is - * negotiated over a link, the input and output lists are merged to form a - * new list containing only the common elements of each list. In the case - * that there were no common elements, a format conversion is necessary. - * Otherwise, the lists are merged, and all other links which reference - * either of the format lists involved in the merge are also affected. - * - * For example, consider the filter chain: - * filter (a) --> (b) filter (b) --> (c) filter - * - * where the letters in parenthesis indicate a list of formats supported on - * the input or output of the link. Suppose the lists are as follows: - * (a) = {A, B} - * (b) = {A, B, C} - * (c) = {B, C} - * - * First, the first link's lists are merged, yielding: - * filter (a) --> (a) filter (a) --> (c) filter - * - * Notice that format list (b) now refers to the same list as filter list (a). - * Next, the lists for the second link are merged, yielding: - * filter (a) --> (a) filter (a) --> (a) filter - * - * where (a) = {B}. - * - * Unfortunately, when the format lists at the two ends of a link are merged, - * we must ensure that all links which reference either pre-merge format list - * get updated as well.
