gst/gstclock.*: deprecate old interface and disable functions that aren't in use anymore. Original commit message from CVS: 2004-01-13 Benjamin Otte <in7y118@public.uni-hamburg.de> * gst/gstclock.c: (gst_clock_class_init), (gst_clock_init), (gst_clock_set_speed), (gst_clock_set_active), (gst_clock_is_active), (gst_clock_reset), (gst_clock_handle_discont): * gst/gstclock.h: deprecate old interface and disable functions that aren't in use anymore. * gst/gstelement.h: * gst/gstelement.c: (gst_element_get_time), (gst_element_wait), (gst_element_set_time), (gst_element_adjust_time): add concept of "element time" and functions to get/set this time. * gst/gstelement.c: (gst_element_change_state): update element time correctly. * gst/gstelement.c: (gst_element_get_compatible_pad_filtered): This is a debug message, not a g_critical. * gst/gstpad.c: (gst_pad_event_default): handle discontinuous events right with element time. * gst/gstscheduler.c: (gst_scheduler_state_transition): update to clocking fixes. set clocks on elements in READY=>PAUSED. The old behaviour caused a wrong element time on the first element that started playing. * gst/schedulers/gstbasicscheduler.c: (gst_basic_scheduler_class_init): * gst/schedulers/gstoptimalscheduler.c: (gst_opt_scheduler_class_init): remove code that just implements the default behaviour. * gst/elements/gstfakesink.c: (gst_fakesink_chain): update to use new clocking functions * testsuite/clock/clock1.c: (gst_clock_debug), (main): * testsuite/clock/clock2.c: (gst_clock_debug), (main): update to test new element time. * gst/autoplug/gstspideridentity.c: (gst_spider_identity_getcaps): use _get_allowed_caps instead of _get_caps. This catches filtered caps correctly. * testsuite/debug/commandline.c: update for new GST_DEBUG syntax. * testsuite/threads/Makefile.am: disable a test that only works sometimes.
