gst/mpegtsparse/: pat-info is now a signal not a GObject property that gets notified.
Original commit message from CVS: patch by: Alessandro Decina * gst/mpegtsparse/mpegtspacketizer.c: * gst/mpegtsparse/mpegtspacketizer.h: * gst/mpegtsparse/mpegtsparse.c: * gst/mpegtsparse/mpegtsparse.h: pat-info is now a signal not a GObject property that gets notified. pat-info, pmt-info now instead of passing a GObject as a parameter, pass a GstStructure. New signals: nit-info, sdt-info, eit-info for DVB SI information * sys/dvb/camconditionalaccess.c: * sys/dvb/camconditionalaccess.h: * sys/dvb/camdevice.c: * sys/dvb/camdevice.h: * sys/dvb/camswclient.c: * sys/dvb/camswclient.h: * sys/dvb/camutils.c: * sys/dvb/camutils.h: Cam code now uses the pmt GstStructure passed from mpegtsparse signals rather than the GObject. * sys/dvb/dvbbasebin.c: Use new signals in mpegtsparse and use GstStructures as per mpegtsparse's modified API.
