Benjamin Otte	d7c64c071b	gst/gstcaps.c: fix bug when converting from empty string. ... Original commit message from CVS: * gst/gstcaps.c: (gst_caps_from_string_inplace): fix bug when converting from empty string. * gst/gstcaps.c: (gst_caps_new_any), (gst_caps_new_simple), (gst_caps_new_full_valist), (gst_caps_copy), (gst_caps_copy_1): use gst_caps_new_empty to allocate a new caps. Only that function allocates memory for caps now. * gst/gstcaps.c: (gst_caps_remove_and_get_structure), (gst_caps_remove_structure): add ability to remove one structure (but not to header yet) * gst/gstcaps.c: (gst_caps_compare_structures), (gst_caps_simplify), (gst_caps_structure_figure_out_union), (gst_caps_structure_simplify), (gst_caps_do_simplify), * gst/gstcaps.h: add gst_caps_do_simplify that tries to simplify a caps in place. Deprecate old gst_caps_simplify function. * testsuite/caps/caps.h: add caps.h containing a common set of caps to test against. * testsuite/caps/sets.c: (check_caps), (main): use it. * testsuite/caps/.cvsignore: * testsuite/caps/Makefile.am: * testsuite/caps/simplify.c: (check_caps), (main): add test to check correctness and efficency of caps simplification.	2004-04-22 02:35:13 +00:00
Benjamin Otte	614b4d1627	gst/gstcaps.c: check for ANY caps before appending/unioning ... Original commit message from CVS: * gst/gstcaps.c: (gst_caps_append), (gst_caps_union): check for ANY caps before appending/unioning * gst/gstcaps.c: (gst_caps_is_subset), (gst_caps_is_equal), (gst_caps_structure_subtract_field), (gst_caps_structure_subtract), (gst_caps_subtract): * gst/gstcaps.h: add gst_caps_is_equal, gst_caps_is_subset and gst_caps_subtract to the API. deprecate gst_caps_is_equal_fixed * gst/gstpad.c: (gst_pad_try_set_caps): * gst/gstqueue.c: (gst_queue_link): s/gst_caps_is_equal_fixed/gst_caps_is_equal/ * gst/gststructure.c: (gst_structure_get_name_id): * gst/gststructure.h: add function gst_structure_get_name_id * gst/gstvalue.c: (gst_value_subtract_int_int_range), (gst_value_create_new_range), (gst_value_subtract_int_range_int), (gst_value_subtract_int_range_int_range), (gst_value_subtract_double_double_range), (gst_value_subtract_double_range_double), (gst_value_subtract_double_range_double_range), (gst_value_subtract_from_list), (gst_value_subtract_list), (gst_value_can_intersect), (gst_value_subtract), (gst_value_can_subtract), (gst_value_register_subtract_func), (_gst_value_initialize): * gst/gstvalue.h: add support for subtracting values from each other. Note that subtracting means subtracting as in set theory. Required for caps stuff above. * testsuite/caps/.cvsignore: * testsuite/caps/Makefile.am: * testsuite/caps/erathostenes.c: (erathostenes), (main): * testsuite/caps/sets.c: (check_caps), (main): * testsuite/caps/subtract.c: (check_caps), (main): add tests for subtraction and equality code.	2004-04-21 03:25:13 +00:00
