gst/qtdemux/: Add X-QT depayloader that will eventually share code with the demuxer.
Original commit message from CVS: * gst/qtdemux/Makefile.am: * gst/qtdemux/gstrtpxqtdepay.c: (gst_rtp_xqt_depay_base_init), (gst_rtp_xqt_depay_class_init), (gst_rtp_xqt_depay_init), (gst_rtp_xqt_depay_finalize), (gst_rtp_quicktime_parse_sd), (gst_rtp_xqt_depay_setcaps), (gst_rtp_xqt_depay_process), (gst_rtp_xqt_depay_set_property), (gst_rtp_xqt_depay_get_property), (gst_rtp_xqt_depay_change_state), (gst_rtp_xqt_depay_plugin_init): * gst/qtdemux/gstrtpxqtdepay.h: * gst/qtdemux/qtdemux.c: (gst_qtdemux_base_init), (gst_qtdemux_loop_state_header), (gst_qtdemux_loop), (qtdemux_parse_moov), (qtdemux_parse_container), (qtdemux_parse_node), (gst_qtdemux_add_stream), (qtdemux_parse_trak), (qtdemux_audio_caps): * gst/qtdemux/qtdemux.h: * gst/qtdemux/quicktime.c: (plugin_init): Add X-QT depayloader that will eventually share code with the demuxer. Make new plugin entry point with quicktime releated stuff.
