ext/alsa/gstalsa.c: start clock on PAUSED=>PLAYING, not later
Original commit message from CVS: 2004-01-31 Benjamin Otte <in7y118@public.uni-hamburg.de> * ext/alsa/gstalsa.c: (gst_alsa_change_state), (gst_alsa_start): start clock on PAUSED=>PLAYING, not later * ext/alsa/gstalsasink.c: (gst_alsa_sink_check_event): extract correct time for different discont formats (gst_alsa_sink_get_time): don't segfault when no format is negotiated yet, just return 0 * ext/ogg/gstoggdemux.c: (gst_ogg_demux_src_event), (gst_ogg_demux_handle_event), (gst_ogg_demux_push), (gst_ogg_pad_push): handle flush and discont events correctly * ext/vorbis/vorbisdec.c: (vorbis_dec_event), (vorbis_dec_chain): handle discont events correctly
