Original commit message from CVS: * ext/mad/gstmad.c: (gst_mad_dispose), (gst_mad_sink_event), (gst_mad_chain): * ext/mad/gstmad.h: * gst/mpegaudioparse/gstmpegaudioparse.c: (gst_mp3parse_dispose), (gst_mp3parse_sink_event), (gst_mp3parse_emit_frame): * gst/mpegaudioparse/gstmpegaudioparse.h: Cache all events except EOS if we still have to send a NEWSEGMENT event. This will let TAG events be forwarded until after decodebin to an encoder for example as decodebin only links the pads after NEWSEGMENT. Fixes bug #518933.
