Original commit message from CVS: * gst/playback/Makefile.am: * gst/playback/gstplayback.c: (plugin_init): * gst/playback/test7.c: (update_scale), (warning_cb), (error_cb), (eos_cb), (about_to_finish_cb), (main): Add playbin2. Added gapless playback example. * gst/playback/gstplaybasebin.c: * gst/playback/gstplaybasebin.h: * gst/playback/gstplaybin.c: (gst_play_bin_plugin_init): * gst/playback/gstqueue2.c: * gst/playback/test.c: * gst/playback/gsturidecodebin.c: (gst_uri_decode_bin_class_init), (pad_removed_cb): * gst/playback/gststreaminfo.h: Change email. * gst/playback/gstplaybin2.c: (gst_play_bin_get_type), (gst_play_bin_class_init), (init_group), (gst_play_bin_init), (gst_play_bin_dispose), (gst_play_bin_set_uri), (gst_play_bin_set_suburi), (gst_play_bin_set_property), (gst_play_bin_get_property), (gst_play_bin_handle_message), (pad_added_cb), (pad_removed_cb), (no_more_pads_cb), (perform_eos), (drained_cb), (unlink_group), (activate_group), (setup_next_source), (gst_play_bin_change_state), (gst_play_bin2_plugin_init): Added raw first version of playbin2. Does chained oggs and gapless playback fine. No support for raw sinks yet. No visualisations or subtitles yet. * gst/playback/gstplaysink.c: (gst_play_sink_get_type), (gst_play_sink_class_init), (gst_play_sink_init), (gst_play_sink_dispose), (gst_play_sink_vis_unblocked), (gst_play_sink_vis_blocked), (gst_play_sink_set_video_sink), (gst_play_sink_set_audio_sink), (gst_play_sink_set_vis_plugin), (gst_play_sink_set_property), (gst_play_sink_get_property), (post_missing_element_message), (free_chain), (add_chain), (activate_chain), (gen_video_chain), (gen_text_element), (gen_audio_chain), (gen_vis_element), (gst_play_sink_get_mode), (gst_play_sink_set_mode), (gst_play_sink_request_pad), (gst_play_sink_release_pad), (gst_play_sink_send_event_to_sink), (gst_play_sink_send_event), (gst_play_sink_change_state): * gst/playback/gstplaysink.h: Added Element that abstracts the sinks and their pipelines for playbin2.
