Original commit message from CVS: * gst/asfdemux/Makefile.am: * gst/asfdemux/asfpacket.c: (asf_packet_read_varlen_int), (asf_packet_create_payload_buffer), (asf_payload_find_previous_fragment), (gst_asf_payload_queue_for_stream), (gst_asf_demux_parse_payload), (gst_asf_demux_parse_packet): * gst/asfdemux/asfpacket.h: * gst/asfdemux/gstasfdemux.c: (gst_asf_demux_reset_stream_state_after_discont), (gst_asf_demux_push_complete_payloads), (gst_asf_demux_loop), (gst_asf_demux_setup_pad), (gst_asf_demux_descramble_buffer), (gst_asf_demux_process_chunk): * gst/asfdemux/gstasfdemux.h: New packet parsing code: should put halfway decent timestamps on buffers, and might even set the appropriate keyframe/discont buffer flags from time to time (and even if it doesn't, I'm at least able to debug this code); only used in pull-mode so far. Still needs some more work, like payload extensions parsing and proper flow aggregation, and stream activation based on preroll. Stay tuned.
