gst/playback/gstplaybin2.c: Get the object data correct so that we can remove our channels correctly.
Original commit message from CVS: * gst/playback/gstplaybin2.c: (pad_added_cb), (pad_removed_cb), (no_more_pads_cb): Get the object data correct so that we can remove our channels correctly. * gst/playback/gstplaysink.c: (gen_video_chain), (gen_audio_chain), (gen_vis_chain), (gst_play_sink_reconfigure), (gst_play_sink_request_pad): Add option to disable async behaviour in the sinks when possible. This makes it possible to avoid an audio queue when dealing with visualisations. Add option to add a queue for the audio path. * tests/examples/seek/seek.c: (clear_streams), (update_streams), (main): Disable the vis checkbox to match the defaults of playbin2. Only get the stream info when we need to.
