So this is *your* aacparse as well and not GStreamer's, right? > 0:00:01.077222307 1989 0xaf5c8 INFO GST_EVENT > gstevent.c:591:gst_event_new_new_segment_full: creating newsegment > update 0, rate 1.000000, format GST_FORMAT_TIME, start > 0:00:00.000000000, stop 99:99:99.999999999, position 0:00:00.000000000 > > 0:00:01.078684857 1989 0xaf5c8 ERROR savsdec_aac > gstsavsdecaac.c:345:gst_savsdecaac_sink_event: dropping newsegment > event in format (null) It sees unlikely that the event has suddenly changed in between those two debug lines. More likely a programming / event parsing / debug log printing error in your aac decoder code. > 0:00:01.079197646 1989 0xaf5c8 WARN savs_aacparser > savs_aac_parser.c:1305:savs_aac_parser_push_frame: failed to push > buffer. reason: not-negotiated This is the actual error though. It means you either forgot to put caps on the buffers you are pushing out, or you put caps on it that are incompatible with the element downstream of your decoder. Cheers -Tim
