There is actually a playbin or decodebin blocking this fix. If the second pad
is added much later than the first the pipeline will stall in any case, no
matter what newsegment events are sent (Wim knows details ;) ).

Correct for the above example would probably be (only)
gst_event_new_new_segment(False, 1.0, GST_FORMAT_TIME, 0,
GST_CLOCK_TIME_NONE, 5 * GST_SECOND);


If all pads would be added almost at the same time (+- ~2 seconds) the above
would work. Also for gaps one has to send filler newsegment events every
second.

As this can't be done here the first thing to fix is decodebin/playbin to
handle late-added pads properly. I have a patch locally to fix the segment
handling of flvdemux that would work after the decodebin/playbin fix ;)
