Original commit message from CVS: * sys/sunaudio/gstsunaudiomixerctrl.c: * sys/sunaudio/gstsunaudiosrc.c: Use the sunaudio debug category. * sys/sunaudio/gstsunaudiosink.c: (gst_sunaudiosink_finalize), (gst_sunaudiosink_class_init), (gst_sunaudiosink_init), (gst_sunaudiosink_set_property), (gst_sunaudiosink_get_property), (gst_sunaudiosink_open), (gst_sunaudiosink_close), (gst_sunaudiosink_prepare), (gst_sunaudio_sink_do_delay), (gst_sunaudiosink_write), (gst_sunaudiosink_delay), (gst_sunaudiosink_reset): * sys/sunaudio/gstsunaudiosink.h: Uses the sunaudio debug category for all debug output Implements the _delay() callback to synchronise video playback better Change the segtotal and segsize values back to the parent class defaults (taken from buffer_time and latency_times of 200ms and 10ms respectively) Measure the samples written to the device vs. played. Keep track of segments in the device by writing empty eof frames, and sleep using a GCond when we get too far ahead and risk overrunning the sink's ringbuffer. Fixes: #360673
