Thank you!  Yeah, I don't know what was going on at my end, I just erased
everything, recompiled from scratch, and now it's working again.  I think some
stuff moved between packages and I was maybe getting weird symbol collisions.

Anyway, yeah so then I found that problem you spotted too:  in the unit tests
the resampler isn't always resetting the timestamp tracking info.  Was the
problem with the unit test or the element?  It looks to me like the unit test
isn't always preceding each test stream with a newsegment event, but I don't
know if that's a problem with the unit test or if the element is supposed to
deal with that.
