ext/faad/gstfaad.c: Fix negotiation.
Original commit message from CVS: * ext/faad/gstfaad.c: (gst_faad_init), (gst_faad_srcgetcaps), (gst_faad_chain): Fix negotiation. * ext/librfb/gstrfbsrc.c: (gst_rfbsrc_handle_src_event): Add key and button events. * gst-libs/gst/floatcast/floatcast.h: Fix a minor bug in this dung heap of code. * gst-libs/gst/gconf/gstreamer-gconf-uninstalled.pc.in: gstgconf depends on gconf * gst-libs/gst/gconf/gstreamer-gconf.pc.in: same * gst-libs/gst/play/play.c: (gst_play_pipeline_setup), (gst_play_video_fixate), (gst_play_audio_fixate): Add a fixate function to encourage better negotiation, particularly between audioconvert and osssink. * gst/audioconvert/gstaudioconvert.c: (gst_audio_convert_chain): * gst/qtdemux/qtdemux.c: (qtdemux_parse_trak): Make some debugging more important. * gst/typefind/gsttypefindfunctions.c: Fix mistake in flash typefinding. * gst/vbidec/vbiscreen.c: Add glib header * pkgconfig/gstreamer-play.pc.in: Depends on gst-interfaces.
