Original commit message from CVS: Includes patch by: Paul Davis <paul at linuxaudiosystems dot com> * ext/jack/Makefile.am: * ext/jack/gstjackaudioclient.c: (gst_jack_audio_client_init), (jack_process_cb), (jack_sample_rate_cb), (jack_buffer_size_cb), (jack_shutdown_cb), (connection_find), (gst_jack_audio_make_connection), (gst_jack_audio_get_connection), (gst_jack_audio_unref_connection), (gst_jack_audio_connection_add_client), (gst_jack_audio_connection_remove_client), (gst_jack_audio_client_new), (gst_jack_audio_client_free), (gst_jack_audio_client_get_client), (gst_jack_audio_client_set_active): * ext/jack/gstjackaudioclient.h: Make an object to manage client connections to the jack server which we will use in the future to run selected jack elements with the same jack connection. Make some stuff a bit more threadsafe. Activate the jack client ASAP. * ext/jack/gstjackaudiosink.c: (gst_jack_audio_sink_allocate_channels), (gst_jack_audio_sink_free_channels), (jack_process_cb), (gst_jack_ring_buffer_open_device), (gst_jack_ring_buffer_close_device), (gst_jack_ring_buffer_acquire), (gst_jack_ring_buffer_release), (gst_jack_audio_sink_class_init), (gst_jack_audio_sink_init), (gst_jack_audio_sink_getcaps): * ext/jack/gstjackaudiosink.h: Use new client object to manage connections. Don't remove and recreate all ports, try to reuse them.
